Greetings,

I need to replace a Vetta II Combo amp master volume pot.  Can I order the pot from Line 6, or get specs for it, so I can buy one?  Better yet, can I replace the stupid, pain-in-the-butt linear pot with a logarithmic (audio) pot?  That is what should have been in it from day one.

My wife has a Vetta II Combo Amp with what appears to be a faulty or dirty volume pot.  She'll be playing along at a low level (practicing in the bedroom) when the volume will suddenly spike to maximum.  It only took a couple occurances of that to make her afraid to use it.  I'm concerned that it may blow the speakers.  I have been unable to reproduce her experience, but have been able to make it better for her by quickly moving the master volume from min to max a couple dozen times.  I fooled around with it for a while and was able to get a minor spike while not touching the knob, to get no change while turning the knob, to get minor spikes while turning the knob, and the like.

Before I open the thing up and attempt to repair the pot, I want to know if I can buy a replacement.  Replacing it would be better than tring to fix it.

I'm a electrical engineer who has been repairing and replacing pots in devices since I was a kid fixing the neighbors pong and Atari controllers.  I hate the things, sure they are cheap and get the job done most of the time, but they are horribly imprecise and inevitably prone to nasty failures.  I've converted most everything that I presonally use or design to Hall or optical sensors for many years.  Once I get her amp fixed, I may see if there is a suitable Hall sensor out there for next time...

Thank you
