Hi guys!

I'm having a little problem using my solo switch. I've tried setting the knobs to LOOP ON and FOOTSWITCH (and I've also tried every possible position for every knob.) and the sound of my amp changes to very treble-ish and the volume drops down to ridiculously low. It sounds like a 10W amp, not a dual rectifier. Even when cranked it's still quieter than the loop off and channel volume at 9:00. So the solo switch actually works but the overall sound isn't normal when the loop is switched on.

When the fx-loop is bypassed the amp works just fine but when I try using the solo-switch, the problem occurs, and as we know the fx-loop must be switched on to use the solo-switch.
The tubes are about a year old so I don't think they are causing the problem.
Is there something I'm missing? Any ideas?

Thanks, didn't know this existed

You're welcome! I found that forum when I bought my Roadster. Awesome info on Mesas. I learned about cathode follower circuits thanks to your post!
