Slight thread derailment, but rather than start a new one - I'm getting some problems at high levels with my Laney Nexus bass head seemingly vibrating in sympathy with the matching 1x15" cab it sits on a producing a low-level crackling noise with the very lowest notes.
I'm aware that it's probably a dodgy joint on a circuit board somewhere but there's a LOT of board real estate in there; do you think that isolating head from cab as muc as is possible (Gramma pad, hockey pucks, rubber feet, whatever) might help? When I can afford to and don't need the head for a bit I'm planning to get it into Laney for a service, but as a stop-gap?
