I finished modding my Epiphone Valve Jr. head yesterday, installing BitMo’s Trio modifications. The amp now has a beautiful mid-range presence, has dropped is muddy bottom-end (especially before noon on the volume), and sounds like a much more high-end tube amp.
The new knob on the left adjusts tone (and works very well), and if you pull it out will give your signal a nice boost.
The toggle between the input and volume knob acts as a voicing switch; low-gain (very clean!), mid-gain, and high-gain (almost Matchless-like).
If you have one of these heads sitting around, do yourself the favor of getting the BitMo Trio mod kit and believe me when I say that you will not be sorry. It’s my main amplifier now. And when combined with BitMo’s 10-uattor, I can play at bedroom levels or line-out to ProTools.
