I recently picked up a Mesa F-30, which I'm really enjoying except for one thing. I find the overdrive channel, especially with a reasonable amount of gain, to get a bit muddy and lose definition on the notes. I've tried eqing, which helped a bit, but by no means solved the problem.

I guess what I'm looking for is some kind of pedal that will give the amp a little more gain, and an overall 'tighter' sort of sound. Thanks
