I have a Blues Jr Tweed v3 which I have hardly played. Today I spent a few minutes with it and got some decent fuzzy blues sound out of it. You have to turn all three tone controls up to 8-10, the regular volume to 10, the fat on, and then adjust the master volume. Just letting you know, it sounds much hotter (yeah it hums, but if you are playing you'd never hear it.) I believe what you will hear is the proper and best tone this amp is capable of. Used a Strat, forgive me, lol. Sounds so much better this way like a real amp. Honestly I'm not much impressed with the regular clean tones from it, and think it was intended to be run all out. It has a great punch when used as noted above. To my ears it sounds somewhat like what a great vintage tube amp should sound like, but it's own thing. Really enjoy it. The reverb unfortunately sounds way too springy above 3. I may have to move some tubes around, like put the reverb tube into V1 or something. I haven't tried any tube swapping at all on it, I'm sure that would change it up a bit. But I'm more than satisfied with the hot tone. Have a good one, and if you haven't run it all out, you're going to love it.
