so the subject of a blend knob came up a few times today while i was browsing and it made me wonder about it a bit. would adding a blend pot be the same as adding a blend pot to say.. a jazz bass? or any bass with two pickups? i got parts to put together a true bypass pedal that i wanted for some of the cheaper effects i had laying around. i was wondering if i wired a blend pot like the ones used on basses would do the same in a pedal? to me it seems like theres no reason it shouldnt.. but is that all a blend knob in a pedal is? or is there some kind of buffer needed?
