Found this digitech pedal for about $125 blue metal case looks like the digitech whammy but with modulation effects an XP series. I think its new but old stock very old stock any one got any info on them are they any good, useful effects? I already have a Korg ax1000g and ax1b for my bass would this give me something they don't? Just the usual questions as well is it true bypass? Analog/digital? Thanks in advance.
