Hi, again. This is an Ibanez Sb-7 synth bass pedal (I know you already knew that). I haven't used it much, so I thought I'd see if anyone to buy or trade for it. It's got the knobs that click into the case so you don't bump them when you're stomping it on. They pop up when you press on them. It has three seetings, auto-wah, synth 1 and synth 2. Auto-wah is, well, an auto-wah. Synth 1 is a warm, overdriven EV filter/autowah (I've never figured out the difference) sound. Synth 2 is a little more extreme, more distorted, opens up more. Add to that the slow and fast decay rates, sensitivity, frequency, and resonance knobs, and you've got a very versatile pedal. Sounds cool on its own, but it is quite a chameleon, and can add something interesting to just about every other effect (distortion, flange, and wah are especially good compliments). I have in the past had some trouble using a power adaptor with it. Sometimes, the sound will cut out. I think the power jack is loose. I've never had any trouble using batteries, though. This, obviously, effects the value, but not by much. It would pretty easy/cheap to fix. I will of course consider offers and trades accordingly. I'll look into how much these go for on EBay, but make me an offer. I'd also be interested in trades. Whatever sort of pedal or goody of relatively equal value you have, let me know. Sound samples! Thanks for looking!
