If I roll off volume pot on guitar while using channel 3 or use a low output guitar I get a fuzzy kind of distortion that becomes dominant in the amp sound, and not in a good kind of fuzz way.
so I replaced the tube in the Revolt with a Jan 5751 and not only did the fuzzy problem go away but the characteristic ‘less gain’ nature of that tube has improved everything about the Revolt for my taste anyway. And fear not, even with that ‘lower gain’ tube you can still get ridiculous excess gain from channels 2 and 3.
Channel 3, before the tube swap, even when I hit the input hard enough to avoid the fuzzy problem was too much gain and too noisy so I didn’t ever use it. Now it is excellent!
Channel 1 is basically the same as it was before just slightly lower volume but now I can raise the volume on that channel to compensate and find I don’t necessarily need the boost engaged to get a nice sound. The boost still adds some gain and accents some high mids like before but I don’t feel I have to have it on all that time just to use the channel.
Channel 2 is unchanged other than I think I raise the gain pot ever so slightly to get it to where it was before the swap.
Channel 2 was always the reason I knew I’d keep Revolt in spite of the problem fuzz on channel 3 and the Channel 1 needing the boost just to get a decent voice from it.
4 screws on the bottom, carefully flip the bottom over carefully protecting the ribbon connectors and support the small vertical board the tube socket is mounted to while replacing the tube. Takes about ten minutes.
Now my Revolt Guitar has gone from almost perfect to everything I hoped it would be.
