Hi all, hope its OK to revive this ancient thread. I recently purchased a 1979 butterscotch Artist RD and all of the above comments apply - awesome beast !
It has 4 Gibson 'speed control' - type knobs. The 2 that control the active bass / treble boost / cut circuitry are unusual, in that the numbers go 5 - 0 - 5 instead of the usual 0 - 10 ! Does anyone know of a source of replacements for these as one of mine has a fracture in the perspex (OK, I am a pedant). Perhaps they were unique to these RDs... - thanks, Chris
