Hello fellow Tbassers. I own a Tech 21 VT Bass distortion pedal. However I'm dissatisfied with the absence of a blend control. Does anybody know the cost of such a modification, if I take it to a technician and he adds a blend knob? I'd prefer an answer in euros if possible. I'm from Greece, but I doubt I'll find someone Greek here who can tell me the exact cost in Greece. Thanks in advance!
