Home-Built Custom 12-String Bass

Custom built by Matthias "12stringbassman" Haydn in Germany in 2005.
Matthias states, "The body shape is my own design."

 

This 12 is neck through, one-piece flamed maple. Ebony fingerboard, 34" long scale with 26 frets. The angled headstock is jointed to the neck with a dovetail groove and has a binding made of the same piece of ebony as the fingerboard.

Electronics: There are two Kent Armstrong soap-bar humbuckers, balance and volume pots, and the two other pots are treble and bass tone controls.

Matthias told us, "As a special feature there are two cigarette burns under the E-strings. After doing that I quit smoking... ;-)"

 

The body wings are made of American walnut and flamed maple.
The bass was finished with linseed oil, tung oil, orange-oil and Carnauba wax.

 

The piece of the fingerboard with frets # 23-26 is removable
with three screws  for access to the two truss rod nuts.

 

The bridge and tailpiece are self-made of 5mm-thick brass (approx. 7/32")
with a sustain block and 8 individual adjustable string saddles.

 

The XLR connector is used for powering the electronics from the preamp's power supply.

 

The headstock is a copy of the Dean Rhapsody 12-string bass headstock.
"I took the pic from your web site... :-)" writes Matthias.

Kluson tuning machines and a brass nut.

Thanks Matthias!
