I had an amp problem with hum, and I posted here and got a lot of suggestions for things to try to redcuce/eliminate it. I've done most of those, and have pretty much eliminated the problem. Most of it was caused by one of those 'one-spot' type of power supplies - once I switched to the power plus 2, most of the hum problems went away. I am also now running my amp and pedals through a furman power conditioner. Although that did not seem to affect the hum, it does appear to be making everything function more consistently from location to location.
I have one weird humming problem still. Whenever I click on my effects (either my sparkle drive or deja vibe) I will here a momentary BUZZ while it is switching. But ONLY if I have not grounded the strings of my guitar (by palm muting them). If I have my hand on the strings, no switching BUZZ.
To me this points to a ground problem... but where? In the guitar, in the circuit I am plugged into, in the amp, or in one of the effects?
It's not that big a deal, normally when playing it does not even come up, I only discovered it while switching effects on and off with the guitar on the guitar stand after re-ordering some effects, otherwise I might not have noticed it at all. However, if it is a ground problem, I would like to find and fix it.
Thanks for any help.
