My warwick buzzes to much. What could it be?

I recently bought a warwick stage 1 and have notice that it buzzes to much. Its not really a growl but a buzz. At first I thought it was the battery , then the action, then the strings. After changing and fixing all the of the those things I still had the same problem. So I took it a guitar repairmen in houston so he could see if he could fix. He said that its the characteristic of preamp or something is wrong with it. Does anybody got any on what could it be?

Is it an electrical "humming" sound. Does it get a lot worse if you turn the treble up? Does it get quieter when you touch the strings and louder with your hand off of the bass? Could be a grounding issue, or just a noisy preamp.

You haven't been descriptive enough. This could be trivial to fix, or it could mean some $$$.
 
It's not a Buzz-ard is it?:D

Seriously does the 'buzz' come and go as you move around, particularly in a circle?

Also, what type of amp are you using and how do you, set the bass (particularly the treble) and the amp (particularly the gain, and treble/presence side)
 
The buzz gets worse when I turn the volume up. It sound like if it has a built in overdrive. I've tried on an ampeg, swr, hartke, fender, and aguilar amp. And it has the same problem on all of them.
 
its a volume buzz, its not fret noise, and its not high freq treble noise. It literally sounds like if the bass has some overdrive, but not in a cool growly way like your typical warwick sound. It gets worse when I turn the volume up. I've tried it on many different amps already. So I know its not the amp. I also plugged it directly into a PA system at a church that I play at sometimes, so it has nothing to do with the amp at all. It doesnt make a difference if i turn the treble, bass, mids up or down. The sound is still there regardless.
 
If it leaves the Warwick factory, then it's nothing less than perfect. Maybe it could have been messed with before you bought it?

Wow, so Warwick has never had a factory defect get out into the public? They must spend hundreds of thousands on QC every year, and have at least 20 people hand checking every single mass produced bass that they make.:rolleyes:
 
What is a gain trimpot and what can I do to fix it?

Gain trimpots are located in the control cavity, either on the circuit board or preamp module, whichever the bass has. Not all active basses have them, but a lot of them do. Where are you located? Have you tried your local distributor, or contacted Warwick?

The Warwick forum may be worth a try too. http://forum.warwick.de/?katID=14571&cl=EN
 
Maybe I should clarify a little....I've had nothing but problems with warwicks, very similar to what you're describing. It could be several issues, mechanical (but you said it's not) and electronic issues have always been a problem, I could never get a decent sound of of it....lots of "buzzing" as you describe it.
 
Your bass' gain trimpot is not often located on an amp :D I mean if your bass' preamp has a gain trimpot, it may be the issue.

The "Stage I" basses were quite "high-end" when released - I think they are very likely to have trim pots - but then what kind of guitar/bass tech wouldn't look in the control cavity for this...:eyebrow: ?
