Just curious what happenes in the preamp section regarding the valves when the fat switch is engaged.<br /> I think on many two channel amps the lead channel brings in the v2 or v3 or both but curious how you add gain on a single channel blues junior.<br /> thanks.

Thanks Modal, <br /> I knew 12ax7's are two tubes in one glass and now I know it's v2 mp that steps up the gain similar to a two channel amp.<br /> <br /> Now> One more question is v3 the phase inverter and reverb tube?<br />

My understanding is the reverb tank is driven by solid state amplifiers. The Blues Junior doesn't have tube driven reverb.<br /> <br />
