wacky willies is definately the best, but there is place called radar electronics, i think it's radar, anyway. a while ago somebody told me about a place near the river on the east side, called j-something, maybe. also, if you ever find yourself at berbati's, talk to dave hite, the soundguy there. he is a wealth of information on low tech tweaks, a good friend of mine, and he's been asking "what does this do?" for longer than i've been alive.
