full rosewood neck that hardly ever bends or detunes and brings sustain without boomy bass
extremely sophisticated CNC routed headstock with magnetic covers
custom modified Gotoh string clamping machine heads: just insert the string and start winding it up. Here is Rolf’s video manual
this bridge would work well in other guitars. the principles are:
legendary piezo pickup that mechanically and electrically separates strings well and detailed reproduction of the complete string vibration
simply push button and string is locked and plays like any other guitar.
push the button and the string and let the button go. the string has two more frets and is tuned in D so you can play the common drop D chords, but nothing changes for playing the higher frets. only the E needs to be pressed.
a specially designed FET preamp avoids attack problems of the common OPAMP circuits. separate amplification improves quality of the piezo pickup because when switched parallel to mono, one is a charge for the other.
very similar to original, but for 4 strings. switchable priority to make only the lowest played string be processed, so there is only one bass note!
4xAA holds up to 10 times more energy than a 9V block, for a similar price.
still, the guitar consumes quite a lot (it runs for a few hours) so we recommend to use rechargeable accumulators.
unfortunately some of the accumulators like Monacor are slightly thicker than the normal batteries and most of the accus. DO NOT PUSH THEM INVARDS! they may not come out easily!
the eneloop and sistech and many others work well.
with all the GK controls in the instrument any Roland or BOSS hexaphonic equipment can be connected. with the BOSS GR-10, each string can be treated in a computer!
or you can use the connector simply to feed the instrument or use the controls in some other way…
first 1 or 2 digits = year + 2 digits = month + 2 digits = continuous number
so it starts in 2005 with 50301 and Rolf’s ends 2011 with 111245. after his death, Heinz+Matthias mounted the parts stock up to 160752 (the 12 string)
