This is where I was after playing a Fender Twin II for about 5 years. Got tired of crappy pedals (the mid/late 80s weren’t the golden age of stompboxes) and constantly not being impressed with my tone. That’s when I bought my Mesa/Boogie. It touted 3 channels (that was an amazing feat for the time) and promised to simplify and perfect my sound, which it did. The clean channel is beautiful with tons of headroom, ch2 has great crunch and takes dirt pedals like a champ, and ch3 is pure Boogie with blistering gain. I never played the Twin at a gig again. In fact, it was sold to a Russian collector a few years ago and remains as the only piece of gear (other than pedals) I’ve ever sold. Zero remorse. Moral of the story: if you’re not 120% happy with how you sound, change things up drastically until you are.
Here are a couple of examples of tone settings I’ve used with my Fenders:
First, the Twin II...
Then the Bassman...
Master was usually at about 5, so it was loud!
