I cheat and use the Brit Super just so I can get it to clean up. You can tweak it to sound like a Plexi and there's headroom. A treble bleed helps too. The Brit Super has been my go to Marshall since I started with the AX8.
Yea, earlier this week I got everything dialed in at home playing along to the mp3 songs for this weeks service.
At practice Thursday night and my tone was SO treble heavy I couldn't believe it.
In my case I was using the 50W 6CA7. The main culprit was the bright capacitor. Default is 4999 pF.
I had to turn it down to 80 to make it useable.
To make sure the FOH wasn't sending me a poorly EQ'd tone I did an A/B comparison this morning.
AX3 Direct out to my in ears vs. the monitor send to the ME-1. The sound was just the same.
I made it through the service but I was not comfortable with the tone, and it affected my playing.
This is with my Tremonti. It doesn't have a treble bleed. Back at home, I tried a strat with a treble bleed, but the pickups were not right for the tone I am going after.
I also tried the gain enhancer on the Dynamics tab for output compression.
While I could get some difference in tone, it seems like its going to take a while for me to understand how to go back and forth to get it working properly for me, if I can.
All that to say maybe a treble bleed on the Tremonti will be a step in the right direction.
