Post by: LooseChange on March 28, 2012, 08:01:18 am: 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.

Sounded great and lost the weight... Jerry would have been proud.

Sock Turlet board is done and installed.

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