There are a couple of things I am going to try to make the Tele w/G20 quieter.

I am going to try an APC 4-blade 13.8x10 and also a J'Tec Snuffler on the exhaust stack. This will cut down on the power, obviously, but the G20 has way more than enough oomph as is.

A couple of RCU searches and Google searches did not reveal any previous combinations such as this, so the results should be at least interesting. We have one of the Radio Shack noise meters at the field, so I will be able to make some "before" and "after" measurements.
