Sadowsky Semi-Hollow

Hollow-body enthusiasts check out our latest find...this excellent condition Sadowsky Semi-Hollow built in Brooklyn NYC in 2010. Roger Sadowsky has built a rock solid reputation over the decades as a top repairman and excellent builder. He describes his Semi-Hollow model as "an instrument that could produce a tradition jazz tone, yet have the ability to function at much higher volume levels without feedback."

The chambered lightweight spruce center block is part of the magic, it keeps the guitar super lightweight while preventing unwanted feedback. In the neck position with the tone rolled back, nice jazzy sounds are easy to achieve. Crank up the tone knob, flip to the bridge or middle position for some nice brighter sounds. In our research it seems these are pretty rare to find with a factory installed Bigsby. The Bigsby is nice to have to dial in more of your "Gretsch-style" tones with subtle whammy dips.

These are not cheap guitars, the current price tag new is $5,600.00. Here's a great chance to grab a hard-to-find top not quality semi-hollow, offered at $3,499.00 in the original hardshell case.

The specs:

Taylor DDX Doyle Dykes Sig. Model

We remember selling these new back in 2011, the Taylor DDX sig. model has to be one of the easiest-playing steel string acoustics we've encountered. A great choice for someone jamming with others, the wood combo of the Sitka spruce and laminate maple has a bright cut-through the mix tone. A slimmer neck profile, 1-11/16 inch nut width, and super low action add up to a very slick playing guitar.

A few play marks throughout, there's some finish bubbling on the headstock but this seems to be a known issue with this era Taylors. The full gloss black is certainly a stand-out look. $799.00 in Taylor softshell case.

The specs:

  • Grand Auditorium Body with Venetian cutaway
  • Solid Sitka spruce top
  • Arched laminate maple back and sides
  • Full gloss black finish
  • Cream binding
  • Black/white purfling/li>

  • 1-11/16 inch nut width
  • Doyle Dykes signature headstock (some finish wear)
  • Chrome tuning machines
  • Taylor ES-T pickup system
  • Volume/bass/treble controls
  • Very good condition
  • Taylor softshell case included

Taylor 552-ce

Sometimes it can be frustrating if you're searching for a 12-string acoustic that most choices are bigger shapes: Dreadnaughts, Jumbos, etc. Here we have a super comfortable Taylor Grand Concert model, the 552-ce. With the shorter scale and 12-fret to body shape, it's about as petite for a 12-string as you're likely to find.

While most 12's are better for strumming away, this particular model excels for fingerstyle playing. Nice even balance of volume between the lows through highs. Taylor's are known for their brighter, cut-through tone and on a 12-string it comes through even more. Plug in with the Expression 2 system and emphasize a bit more of the bass and warmth with the touch of a knob. Overall in excellent condition with very minimal play wear. Asking $2,299.00 in the Taylor hardshell case.

The specs:

  • Made in El Cajon, CA
  • Grand Concert 12-fret body shape with cutaway
  • Solid cedar top
  • Solid tropical mahogany back and sides
  • V-Class bracing
  • Tortoise pickguard/li>
  • Tortoise binding
  • Gloss body
  • Mahogany neck
  • Ebony bridge and fingerboard
  • Century inlays
  • Satin neck finish
  • 24.8 inch scale
  • 1-7/8 inch nut width
  • Taylor ES-2 pickup system
  • Vol/bass/treble controls
  • Excellent condition
  • Original Taylor hardshell case included

Vintage 1969 M.G. Contreras Classical

Manuel Contreras Sr. was a Madrid native who excelled in guitar building both at the Ramirez workshop and his own. This particular example has an unsigned label, so it was likely made by one of his staff luthiers under his guidance.

The guitar is in fantastic condition. It was well-loved and cared for by a local resident who adored it and even made some reel-to-reel recordings with it. Now that the tone woods are well-seasoned, it projects beautifully. Anyone in the market for a vintage Spanish-made classical guitar needs to come check this one out.

This is a consignment instrument, and the seller has recently reduced the asking price to $3,499.00 including the original case - an exceptional value.

The specs:

  • Label reads: Constructor de Guitarras Calle Mayor, 80 Madrid, 1969
  • Indian rosewood back and sides
  • Spruce top
  • Ebony fretboard
  • Rosewood bridge
  • 656 mm scale
  • 52 mm nut width
  • Lacquer finish
  • Photo of original owner meeting Mr. Contreras with guitar
  • Original hardshell case included
  • Excellent condition

Fender American Standard Precision Bass

A classic bass has just arrived in the Attic! Get that familiar fat and punchy low-end tone with this excellent condition made in 2010 American Standard P-Bass.

The 3-tone sunburst finish is always a familiar and popular color choice, and paired with the maple neck and fingerboard it adds a bit more 'attack' to the sound. The one volume and one tone control keep things easy and straightforward.

One small finish ding on the back, otherwise in excellent-plus condition. Offered at $1,199.00 in the Fender hardshell case.

The specs:

  • Made in Corona, CA in 2010

Martin JC-40 Jumbo

The great gear just keeps arriving weekly here at The Minor Chord! Used Martins are always very popular with our customers, and they go fast. This model JC-40, built in 1993, is certainly one of the rarer models to come through the Attic.

The jumbo body delivers plenty of volume with a boomy bass response. The larger oval soundhole pushes a bit more air as well. Nice to have the cutaway for access up the neck. Martin's 40-Series appointments are tastefully done with the black/white purfling and abalone hexagon fingerboard inlays. Gold tuning machines round out the bling, and there's an active under-saddle pickup for plugged-in performance.

There are a few smaller play-wear marks but overall this guitar is in very good/excellent condition. Asking $2,799.00 including the Martin hardshell case.

The specs:

  • Made in Nazareth, PA in 1993
  • Jumbo body size with cutaway
  • Solid Sitka spruce top
  • Large oval soundhole
  • Solid Indian rosewood back and sides
  • Black pickguard
  • Cream binding

Fender American Standard Stratocaster

Another very clean Strat has arrived to the Attic! The American Standard Stratocaster has long been a Fender mainstay. American-made with quality parts, a great feel, and that sweet expressive sound, the American Strat is a versatile workhorse.

This guitar, along with the 1981 Martin D-28 we recently sold, was from the same owner who kept both in simply amazing condition - especially for a gloss black finish guitar, which typically shows wear and marks. This one is in excellent-plus shape.

Save some money off the new price and get a beautiful guitar that's got 21 years of some broken-in mojo. Asking a very fair $1,199.00 in the original Fender hardshell case.

The specs:

  • Made in Corona, CA in 1999

  • One volume, two tone controls

Gibson SG Modern

Sometimes a customer buys a new instrument, then realizes shortly afterwards that it wasn't what they were looking for. Here's an example and a great opportunity to get a brand new, harder-to-find Gibson model. The SG Modern is certainly a head-turner featuring its AA figured maple top in the Blueberry Fade finish. The ebony fingerboard is a nice extra feature making for even smoother playing than the legendary SG already is.

Because of the wood scheme on this guitar, the tone is a bit brighter than a standard mahogany model. Plenty of volume with the dual Burstbucker Pro humbuckers, they both can be coil-tapped with the push/pull volume knobs for an even brighter and more snappy sound. This would be a great choice for a lead guitar player in a band, easy and quick access up to the 24th fret. Barely a mark on it, in excellent/near mint condition. $1,799.00 in the Gibson case with all original paperwork and case goodies included.

The specs:

  • Made in U.S.A. 2021
  • Thin dual cutaway SG body style

We're always on the lookout for used Taylors, and here's a like-new 214ce-K SB. We often say that Taylor's 100 and 200 series guitars are an excellent choice for getting that Taylor sound and easy playability at a more affordable price point.

This particular instrument features layered koa back and sides, and a solid Sitka spruce top in the Shaded Edgeburst finish. A stand-out looking acoustic for sure, and the Grand Auditorium body is a great shape for both strumming and fingerstyle playing.

Very affordable at only $149.00.

Sigma 000M-15+

Sigma guitars have been around since 1970, sometimes being built under the Martin family of brands. Here is a newer Sigma model. The 000 body size is a go-to for comfort with a good balance of sound for strumming chords and a fitting shape for fingerstyle playing. The solid mahogany top yields a generally warmer tone than the brighter spruce, especially as it breaks in over time. In excellent condition, asking $399.00 with hardshell case included.

The specs:

  • 000 body size
  • Solid mahogany top
  • Mahogany back and sides

Larrivee certainly picked a gorgeous set of wood for this guitar, looks awesome with the maple binding as well. This instrument was extremely well-cared for by it's original owner. Barely a mark on it, it setup beautifully for lights. Nice low action and a sound that is far warmer and punchier than one would expect from the smaller size body.

Vintage 1977 Ampeg B-15N Portaflex

It has been a while since our last Ampeg Portaflex model was in the Attic. We are very pleased to offer to our bass customers this very nice 1977 B-15N. Featuring 30 watts of all tube power, accept no substitute for the real deal tone.

The previous owner really went the extra mile to make this particular amp rock solid. The speaker was replaced with a 15 inch premium Altec 421-8H which was what Ampeg offered as the official upgrade at the time. The fiberglass insulation was upgraded to a modern polyester fill, the gasket was replaced and improved, and the latches are genuine replacements as well. The previous owner even made a bag to house the power cord so when the amp is flipped and put away, the cord doesn't damage the back of the speaker.

Many famous bass players have used this exact model amp, and countless legendary tracks have been recorded with it. Motown legend James Jamerson and the Band's Rick Danko are just a couple that quickly come to mind. Overall in very good condition, rock solid, fully functional and ready for it's next bass journey! $1,499.00.

Fender Joe Strummer Telecaster

Perhaps London is calling on you to check out this awesome limited run Fender Joe Strummer Telecaster. Modeled after his famous beat up 1960's Tele, Fender gave this one the road worn body, neck, and aged parts. A vintage-style feeling and sounding Tele, the neck is super smooth from the worn in finish and the single coils are nice and bright.

This guitar was only made for a couple years and is already climbing in value and has become more collectible. We remember selling this model new at the store back in 2007. Offered at $1,299.00 in the original hardshell case.

Almansa 401-1/2 Half Size Classical

It can be difficult to find a good step-up classical guitar for the young player. Most small classical guitars in this country are starter instruments with laminated tops. The improving young classical player requires a guitar with a solid top for better tone and a higher level of workmanship for responsiveness.

The Almansa 401-1/2 is just such an instrument. Crafted in Spain with a solid red cedar top, this guitar has a short 544mm scale and slightly narrower 48mm nut width. That means it will fit the younger player comfortably but still deliver satisfying tone.

This guitar was originally purchased at The Minor Chord and has had one local owner. That player later graduated to an Almansa 'Senorita' (7/8 size) guitar and traded their 1/2 size model. It's in excellent condition. Offered at $399 with a padded gig bag.

The specs:

  • Made in Spain
  • 544mm (21.4 inch) scale
  • 48mm (1.88 inch) nut width
  • Solid red cedar top
  • Layered mahogany back and sides
  • Open-pore (satin) finish
  • Indian rosewood fingerboard
  • Binding around top
  • Gig bag included

Vintage Squire by Fender 80's Telecaster Japan

It's been a little while since our last made in Japan vintage Fender has come through. This mid 80's telecaster is in great shape and should make someone looking for a tele very happy. Only a couple very minor marks, it looks almost new. The black finish with the maple neck and fingerboard is a solid visual look. Twang away with the two single coils, slimmer neck profile on this one. All original $699.00 including a hardshell case.

The specs:

  • Made in Japan ca. 1984-87

Michael Kelly ST-AB4 'NA'

We've had a few Michael Kelly used instruments come through the Attic, here we have an excellent condition steel string acoustic bass. It's nice to have the option to be heard unplugged if you're just sitting around jamming or songwriting. The Fishman Classic 4 pickup system is now out of production but it does the job well with plenty of E.Q. tweaking if need be. With the cost and size of an upright bass, give this affordable more manageable ST-AB4 some thought. Offered at $399.00 in a hardshell case.

The specs:

  • Made in Korea
  • Acoustic steel string bass
  • Solid spruce top
  • Mahogany back and sides
  • Cream binding

Common problems with used instruments

We see a lot of used instruments at The Minor Chord and a few common issues seem to show up in many of them. If you are thinking of buying an instrument on the private market, make sure you can spot these common flaws.

Lifting bridges

Most bridges on acoustic guitars are simply glued to the guitar top. If the glue joint starts to separate you are looking at a dangerous guitar. Six steel strings exert a huge tension on the bridge, and if it suddenly comes loose it can seriously injure anyone nearby. The staff at The Minor Chord has seen this happen - so we always inspect the bridge of an acoustic guitar before restringing it.

Piece of paper under a lifting bridge

Piece of paper under a lifting bridge

If you can slip a sheet of paper under the bridge of your guitar (see picture) you should relax the string tension immediately and bring the instrument to us for inspection.

An experienced luthier can remove a bridge and reglue it, but the time and labor involved makes the process too expensive for beginner and intermediate guitars.

High action

The distance between the strings and the fingerboard is called the action height. If the action is too high the guitar becomes hard (or even impossible) to play because it takes too much effort to press a string against the fingerboard. In addition, the guitar will probably not play in tune because each string has to be stretched so much (which raises its pitch) as it is pressed down.

Proper action height depends on two factors: The alignment of the neck and the height of the saddle (the point at which the strings rest on the bridge).

Electric and steel-string acoustic guitars usually have a truss rod running down the neck that can be used to adjust neck alignment. Classical-style guitars with nylon strings typically do not have a truss rod, and the only way to realign the neck is for a luthier to remove, shim and reinstall the neck - a major operation. The same operation is required on electrics or steel-string acoustics if the truss rod doesn't have enough available play to achieve the needed adjustment.

Saddle height is easily adjusted on electric guitars using a very small allen-head wrench. The saddles on acoustics and classical nylon strings may simply lift out of the bridge and can be shaved or shimmed to achieve the correct height. If these adjustments cannot bring the action height to a playable level, an expensive neck reset is required.

A low action height is desirable for easy playing but the action cannot be lowered so much that the strings start buzzing against the frets. Inexpensive guitars tend to have uneven frets, which means that the action height cannot be brought very low at all. Resetting or dressing the frets can even them up but it is a time consuming and expensive process, worthwhile only for valuable guitars.

All of these adjustments related to action height are fussy and interrelated. It's best to leave them to an experienced luthier, which means it is usually not economical to rescue an inexpensive guitar having these problems.
