I have this "wing" bass that I made (see avatar), it's tuned up an octave, I call it my stumpy bass. I bought a whammy pedal to drop it an octave (and do many other things). I use the whammy a lot more than I thought I would even with my regular sized basses. When my band goes into jam mode, I'll often record the bass line into the looper, then use the whammy to add some crazy dynamics to the mix. I use it with the wing bass as well, but my complaint is that I can't see what mode the whammy pedal is in without leaning way over and I often accidentally hit the selector knob with my foot while manipulating the pedal. Getting the whammy back to the correct mode requires putting fingers on the knob which really kills the mood. All this to say I somehow had to justify a new pedal. The real wing basses have an option to embed a Nano Pog, I looked into those pedals and they are over $200, while I'm sure it's a nice pedal (I never played through one) I couldn't see spending that much on dedicated octave pedal. I found this Donner pedal that was smaller and seemed to have pretty good reviews. I've only got a few minutes with the Donner, but it definitely produces a more natural sounding bass note than the whammy does. Next is to see if I can make room inside the stumpy so I can embed it inside. I'd hard wire it so it has a single switch on the bass to turn it on - essentially octave drop only. For $45 I guess that's worth the effort, I'd feel bad doing that to a $200 pedal. I'll update this thread if I go forward with the embed.
