Well now I’m curious. I primarily play at home and church and use a 68 Custom PRRI. I love the amp, it is super responsive, and I trust that the amp will work with regular maintenance years from now. But, power scaling on the Tone Master line is really cool. I got to play through the Super Reverb Tone Master locally at a store and was impressed. I’m not sure it felt as warm and responsive as the Princeton but then again I was in a store, different guitar, setting, etc. The overdriven tone was amazing and it was also something shiny and new that weighed so much less than the real thing. Now if they made a Bassman Tone Master, I’d buy immediately. In the interim though, I’m considering selling the PRRI and picking up the Tone Master. anyone else made the switch?
