Problems...

Over the Christmas period, I've played a few gigs with my new amp and some issues have developed which I'm currently trying to fix. Once they're all sorted, I've got some new mods that I want to try out such as replacing the tone stack with something which will give a little more control.

The problems that I've noticed are as follows:
1. If someone plugs into the same socket/extension lead as me, I can "hear" them plugging in through my speaker (not really a huge problem since it only happens before and after a gig)
2. I was playing in gig that was run on generators and I found my amp was more noisy than usual. Also if my hands were close to my strings but not actually touching them I got a high pitched noise from my amp which went away if I actually touched the strings or moved my hands away (the proximity thing makes me think that it might be some weird capacitance thing...). This turned out to be so much of a problem that I couldn't use my amp for the gig and had to DI instead :(
3. A little more recently I've started to get some crackling sounds on low notes. I'm hoping that this turns out to be a dry solder joint, but I'm not hopeful because of the fact that the problem has developed over time and sounds like it's gradually getting worse...

Today's job is to poke around inside my amp checking for dry joints and then to check continuity and voltages at various points to see if I can track down any of the issues.

I'll update once I make any progress!
