hi! i play both bass and guitar, so i'd like to mod my gcb95 to play with bass too (switchable). is this possible? with how much cost/effort? i will have to change the modifying pot (or is it a cap??) anyway, cause it's rather scratchy. maybe i'll do the bypass mod too... or is it then easier (or cheaper) to get a true-bypass guitar and bass wah? thanks for input, enjoy your day! ciao, georg.
