Hey guys
I have several L2000's....
One of them has a very bad HUM,

and I really dont wanna mess with it. It's an '07 I think... I just know there is an issue - because my other L2000's dont do this... I already had one tech look at it, where I got it, and they said there isnt anything wrong with it...

but they are trippin'....
so my question to you guys: Are the any GOOD g & l tech's I could send the bass to, to have this issue nailed down and fixed? My local area stinks for good guys that know what they are doing.
all opinions welcome
thanks guys
