We get to ask a lot,
“With my 1970 JMP cranked, how is it not going to get turned into a Fender sounding amp, though a power amp that’s got 6L6s in it?”.
The answer is that in the guitar amplifier, the power amp stage is designed to behave in a certain way. Like that guitar amps that you’re familiar with, Fenders behave a certain way and they just happen to have 6L6’s. Marshalls behave in a certain way they just happen to have EL34s.
This (the Power Station) is a more neutral Power Amp, its purpose is just to recreate the sound that came out of your amp and send that to the speaker, not add its own coloration. Of course, you can add a little bit of coloration on the extremities (using the presence and depth controls)… but that doesn’t give you a completely different tonal stew. It’s job is not to do that.
Watch Joe compare a JMP circuit amp with and without the Power Station, does it sound like a 6L6 amp?
