Fishman Fission Bass Pedal
This pedal really is Great! I'm not totally blown away because I can't get the stability I was looking for on the higher notes (I get a warbling sound) but I think I'm just asking it to do some things it just can't. Like, taking a hot signal and adding a lot of distortion. In my case, the pedal seems to be a bit more stable,tone wise, with my passive basses. A strong attack on the strings also seems to help, the stability issue, no matter what effect I'm using. It's a lot of fun to play rhythm and lead guitar parts on my bass.
I bought a JamMan looper pedal to go with it an now I'm laying down some loops that sound like an entire band with several different bass lines. My first efforts are Jazz/Rock fusion. It's a blast.
