Hey everyone, so got my first upright bass about two weeks ago (Christopher DB102T since I figure someone will ask). Got it for a fantastic price with a lot of accesories including a pickup. Have been doing a lot of research on bass related topics over the past few months so I've read up on the fact that many piezos need a preamp of roughly 1megaohm input impedance to really sound worthwhile, and mine definitely does need something because plugging it in sounds horrible right now. I play electric bass (amongst quite a number of other string instruments) and I might have the opportunity to pick up a Boss GT-6B for really cheap here in a few weeks. Reading up on the specs it has an input impedance of 1MOhm, so any reason that I couldn't use this multi-effect unit as a preamp for a while? Don't foresee myself seriously playing live as a doubler any time in the near future, so I don't have a need to be amplified. I do have a need for something like the Boss, so I figure it would be nice to know if I could use it for the upright as it would make a dual-investment just in case some of my buddies want to get together and jam regardless of my poor intonation. Here's the info from Boss if you need it by chance: http://www.bossus.com/gear/productdetails.php?ProductId=239 Also on another, possibly important, note, as it might also be the source of the poor sound I am getting, I can't really figure out what the pickup on the bass is, doesn't look like anything else I've come across on the market. It is just a small silver disc mounted to the middle of the bridge (not in the wings or under the foot or anything, just smack dab in the middle) and it leads out to a rather short thin cable which ends in a male 1/4". The cable is short enough though that I surely am going to need to female-female coupler to be able to send it to a longer cord, or to a close-by preamp, as when plugged in I'm right up against my amp. It honestly looks like it might be a homemade radioshack pick-up, figured I'd ask though as it might sound familiar to someone. Heh, makes me realize how little I know about instrument electronics. Thanks everyone, been lurking here on the forums for a long time, the search button is my best friend, but couldn't bring anything up regarding using a multi-effect unit as a preamp.
