A bit off topic but it relates to fret buzz/clank in a way.
At the studio we rehearse at there is a a 4x12 which sits on another cab. Both hard wired together. One of the 12. Inch drivers is majorly buggered. It buzzes a lot. Horrible sound from that cab. The thing is, when the band are playing its not audible at all.
Now i don’t obsess too much about a little buzz when fretting. It’s not audible at all with the band, but having the action to my liking does make a difference
Dave. I had a JCB for a while last year. Really nice bass and i loved its unique tone, but it felt very uncomfortable to play sitting down, which is how I practice at home. It wasn't the neck dive, but the edge of the body digging in to my forearm.
