We are guitarist and we need something like perhaps Dual tracking or metronome, looper synchronizing etc.
just my two cents, while I fully respect your opinion, as a pro guitar player: delays are part of a musician creation process...metronome or similar makes the kpa a gadget thing not a pro thing as it is now.
this of course doesn't mean your request isn't legit. it is indeed! but then what would the kpa become?
as mentioned...just my two cents
