well,
i own a CryBaby, the GCB95 model...should be the original CryBaby...
Hmm.. it sounds bad on humbuckers, secondly, it thins and thrash out ur sound...the bass gets lower, but the treble becomes higher...i used it both as a filter and as a wah.
but is sounds aboslutely nice on fenderr os squire guitars....well..as long as its a all single-coil guitar, it definitely sounds nice...
i like the CryBaby sound, it makes you wanna go wah wah wah on your mouth too when u are playing with it...but i just have to figure out the settings on the amp to use it properly...
