Forgot to add that the I also replace the crappy reverb tank with a MOD tank because the wires in the Fender tank kept breaking. For some reason the reverb foot switch no longer works.

I have a cream board Blues Jr. and I did the Billm mods including the standby switch, replaced the input jack and built a new pine cab for it. Has the original Fender speaker in it and 15 watts is more than enough for me. The mods did a great deal to open up the tone of the amp but I’m not real happy with it when I try to make it crunchy so I rely on pedals. Wondering what improvements have been made for the newer III and IV versions as far as tone and build quality. Has anyone done a comparison of them?

I’ve gigged with these and Pro jr’s for years and never had an issue. And as for volume concerns, if these aren’t loud enough for some guys, they have a band volume issue and not an amp issue. The list of nationals using these in pairs or otherwise is endless, and not short on tone hounds either. Using Twin reverbs in pairs instead of two of these and a few pedals is total overkill and must crush the audience, which if you really care about sound isn’t funny for those that have to listen to it.
