Alright, I've got several older Boss Japan(?) pedals hanging around just collecting dust. The pedals I have are: CE-3 Chorus CS-3 Compressor Sustainer BF-2 Flanger FZ-2 HyperFuzz FT-2 Dynamic Filter I know a number of people out there offer (DIY?) mods / parts upgrade kits. Do you recommend certain mods or kits over others? I see Monte Allums, Fromel, Analogman, Keeley. Who else should I consider? Or, should I just leave them all stock and wait for the archeologists to arrive in a few years? The pedals are all pretty clean with barely any nicks or scratches. Thanks, -bEn r.
