Hey, I got myself great Tweed Princeton clone with 10" G10C/S - 75 inside a while ago, great amp, sweet cleans, super responsive to the touch BUT I cannot get it to overdive naturally, ever. I play telecaster with classic vintage output Callahan Pickups. Even when I dial it to the max and hit strings hard its still super clean and SOOOO LOUD. Why is that? Is it because this amp architecture doesnt allow it to overdrive and naturally its super clean amp (I dont think so, I never played vintage one but saw a few videos and they were able to overdrive it quite nicely)? Or maybe speaker is too efficent? I was wondering if putting Jensen P10R-F inside would help with that?
