Wizard MC: loud popping noise when switching channels...

[Jack71]

Anyone else have this issue with their Modern Classics? It does it whether I'm switching channels using a pedal or manually with the push-pull pot. The pop switching from the dirty channel to the clean is MUCH louder than when going from the clean to the dirty but it does it either way. It's pretty unusable for a live gigging situation, imo. I don't remember my Metal doing this. Also, with the Metal, the foot-switching capability didn't work unless the push-pull pot was in the "out" position. With the Modern Classic it's the opposite. But I don't think that has anything to do with the noise.

I really hope this is not normal. This amp sounds way too damn good to be rendered useless for live shows.

I know of them to make some noise upon switching channels, just the nature of the beast in this case. PM your contact info, I'll call wizard monday morning, and we'll see what we can do. 50 or 100 watt? Not really important, but just wondering which beast you got! Hopefully, I can talk to rick or one of the guys and get this resolved.

It's normal with the type relay he uses. The Metal uses a different relay and is not as noticeable. The footswitch does work backwards from the Metal too, that is also normal.

The MC is my main live amp and the pop is no big deal at all when playing with the band. For the most part, it's easy to get a nice clean using the gtr volume and pickup selection. With all the stage noise the popping won't be a big deal.

George, any idea why he uses that paraticular one in the MC's? I'll have a MC here soon.. Just wondering.

He told me he went with a heavier duty relay than in the Metal. I've had a few times where my Metal wouldn't change channels in certain clubs. It was due to the electric supply being too low. He knew what it was right away when I mentioned it to him. The MC switching has never had any problems in those same clubs...there is a pop like Jack said, but I don't notice it at gigs at all....you get Mikey's?

I see.. Nah, I'm getting one sent from a friend to me to try out.

No I have not had one of those, but mine is a small logo. Gary has one. I'd like to snag a 6L6 Metal sometime.

Like George said thats what I have. 1995 model I believe.

Hmmm, well, if you guys say so, I'll give it a try at the next gig. I don't channel switch much anyway because I don't use the clean channel a lot. I still have to grab a single button foot-switch because the dual button one I have with the stereo jack doesn't work.

Kind of off topic here but, what's the normal bias range for the Modern Classic? I've got JJ E34L's in mine right now which are 30 watt max tubes so, assuming a plate voltage of around 509v, 70% dissipation should be around 41 ma's according to the standard formula. My tubes are running at around 36-37 ma's right now, however, the bias pot has no more upward range! Am I missing something here?
