After testing the LPB 2ube Preamp in the back of a Fender Stage 185, I have to tell all of this masterpiece.

Respectively, it turned this amp into a tube amp. As well, adding to the mix the English Muff’n with the 12AY7’s
to give it an additional drive channel if you will.

Specs:
I set the preamp section in the amplifier (effects loop) to -16dBv and an additional offset gain of -9db. Then, I pushed it all back up with the LPB 2ube, sometimes chained, and sometimes just one side. Giving a massive gain responsibility to the LPB 2ube.
Then of course using the English Muffn’ gets a sort of Vox head sound for the OD channel.

Oh the Velvet!
