Latley I've noticed that when I play my Deluxe Fat Strat through my scxd I've been hearing a high pitched ringing sound in the backround. I've only noticed it on some of the cleaner channels on the scxd. I even hear it on channel 8 and 10 with the gain on 4 or 5. I've changed the tubes in the amp awhile back but I don't think that would be the problem.

My guitar has single coil Tex-Mex pups in the neck and middle position and a DiMarzio super distortion humbucker in the bridge. I've noticed the ringing sound on all 3 pickups. The sound starts to go away when I turn the volume on the guitar down. But I was hoping that there would be another way of solving this problem.

Does anyone have any suggestions? Thanks-Mike

Sounds like a microphonic tube to me.

Hi Pasloade74, if you can do it safely, you could try this.

Hope this helps.

I have not worked on a Super Champ XD I am going to have to get hold of one and look inside because there is something of interest. What is the tube compliment of V1,2,3?

Got it from the schematic.

I see thats what they say for the AC fitments V1,2,3 curious if that was correct. I don't do as much repairs on Hybrid Amps most times they are not worth the cost to fix unless just a tube or a pot. I was looking at the schems.
OK. I should have looked at the controls on the amp. I see what they are doing theres V-1A and V-1B 12AX7 Getting sleepy and I have two amps to fix and return this weekend and this has nothing to do with ether. Got a Vox and a Budda here.

I did swap out the tubes awhile back. I installed an electro-harmonic power tube and 2 ruby tubes 6v6. I don't think its a microphonic tube problem. It sounds fine with a distortion pedal. It only rings when I play a chord on a clear sounding channel or voicing. When the chord rings out and the volume dies down, so does the ringing sound.

I guess I'll try it with another guitar. That should narrow it down. I can also put the origional tubes back in as well.

The odds are astronomically against all three pickups being bad at the same time especially with two different models at that. You can rule them out as your complaint describes more of a sympathetic vibration originating somewhere else.

Not knowing anything about a SuperChamp XD I am assuming there are some built in effects since you mention as many as 10 channels and refer to some as being cleaner. Exactly what do you mean by "cleaner"? Do you mean clean or not? Many people mistakenly believe a signal is considered clean simply if there's no distortion even though it's dripping wet with chorus, flange, reverb and the like. That's not clean. Clean is dry. No processing. Nothing. In my experience heavy mixtures of reverb chorus and compression can exhibit the ringing you describe under certain conditions. Play the amp clean. I mean clean. If the ringing disappears you have your problem isolated. Let us know.

Got a mid '60s Alamo and a Marshall TSL-122 in for repair myself. What model of Budda needs fixing?

I think if it was a microphonic tube you would have been able to tell. Very easy to distinguish.

It's prolly not tubes or any of the basic amp parts if it's only audible on some channels. If it's a problem intrinsic to the actual amplifier section of the unit it will very likely be noticeable on all channels not just 8 and 10.
