Mid 2000’s Fender Blues Junior cream board. I did a bunch of the Billm mods that were designed to get rid of the boxiness that the stock amp has. It has Twin tone stack mod, upgraded tone caps, stiffened power supply caps, upgraded output transformer, adjustable bias, MOD reverb tank, probably a couple more I dont remember right now. Original output transformer and reverb tank will be included and both work fine.
Sounds great! I bought this amp new and took great care of it. No nicks or rips in the tolex or grill cloth. It is my first tube amp but I got another amp recently and I need to downsize on amps.
