Yes, it's just like what Jerry Garcia did with his Twin Reverb in his setup.
I do notice that when patched directly into a Fender power amp 9exactly as if it were a single combo, there seems to be more drive than I would expect. Seems odd due to the exact same circuits just in two pieces.

Thanks!

Is your HT close to what is expected @ twins?

Amazing work!!!

Yes, the HT is exactly the same as the Twin.
I used a Dumbleator (Tube effects loop) as an attenuator and the sound was amazing.

Ran it through a complete Jerry setup. Replaced the Big Twin Reverb on it's side with this.
Sounded great and lost the weight... Jerry would have been proud.

Every time I read "Turlet", I can't help but think of the place where a Redneck goes to relieve himself...  :laugh:
