A couple of months ago I picked up an LSC (50/100w version), yesterday I noticed the gain in the 2nd channel is quite weak compared to what it was prior. I've checked the V1 and V2 tubes swapping with a new tube one at a time and nothing changed. In addition I cleaned all input jacks when I first brought it home. Any ideas? Thanks in advance.

Did you change your EQ?

Keep in mind that all EQ settings and gain are related. Especially the treble.

High treble settings will also increase the perceived "gain" in your signal.
 
No EQ changes. Previously with the drive at 2 o'clock and the gain at 3 o'clock the "gain / distortion" was smoother, more saturated if you will. Now it's as if the amp is just past the edge of breakup, there's overdrive but not what it used to be if this makes sense.

I'll put a call into Mesa on Monday as well.

Thanks,
Scott
 
Did you switch the drive/clean to clean by mistake? On clean, it is almost like channel one.... Drive adds another gain stage and makes the drive knob work to add more gain. The presence also makes a big difference. It can make notes crisp or smooth with sustain
 
I'm not to familiar with the LS series, but you may want to read this:
