Hello GR55 owners.
I play a strat with GK3 pickup.
I just bought a GR55 to replace my Boss GT5/Roland GR20 Combo (nothing wrong with these older machines except their signs of old age).
Imagine my Horror  :o when testing it after setting up the GK pickup and getting no PCM signals from either PCM1 or PCM2!  :'(
I almost contacted the seller to complain bitterly, I checked every darn parameter, factory resetted the unit, searched the web for clues etc....
FINALLY I decided to also try the 13-pin GK cable delivered with the unit to see if it was good or faulty....guess what?
YES ! the PCMs kicked in at once, my new synth started to behave like a new synth !  ;D

Moral of the Story: the older cables may be inappropriate for the newer maschines even if they still work fine for the older units!
