I've got a Carvin BR610 that's been my mighty steed for nearly a decade now. It's been a solid amp, but for the last year or two it's been buzzing something awful. It's to the point that it can't be used for recording and sound men are muting my DI send in between songs. I've gone through and checked that all of the ribbon cables are connected snugly, because I know that you can lose the ground connection if some of them are inserted improperly, but to really suss out the issue, I feel like a tech will need to spend significant time with the amp and schematics, chasing away any potential ground loops and making sure all ground points are making solid contact. I really like the tone of this amp and have come to identify it as "my tone" but feel like I'll be looking at a $200 or greater bill to really get it into shape plus bench time, and then it's still going to be a frayed, rat fur mess with exposed wood. In the opinion of TalkBass, does this seem worthwhile or should I start looking around at alternatives and relegate this one to the practice room?
