I had a revelation this week that all of you may or may not know about already. But since I don't have a solo switch any longer having sold my Stiletto and DR, & I need something to raise the volume for solos, on dirty channels I found boost pedals before the amp just hit the front end harder, and add some distortion and a little volume but not like the Mesa solo switches did which simply increased volume. Well, I have a Boss eq in the loop and it does quite a job of raising the volume with the level set just about flat. Duh...
