My 2 cents...

Both of the guitarist in my band play with low wattage amps.

One uses a two amp setup a 65 Deluxe Reverb & Egnater Renegade set to the 18 watt setting the Fender is clean and the Egnator is dirty.crunch, distorted.
The other guy uses Bogner Alchemist 2x12 (clean&crunch) and Orange Amplifiers Dual Terror in to a Marshall 1960 4x12 cab. (dirty.crunch, distorted).

That is one of the reasons I want a tweaker or supersonic 22 after hearing how good their low wattage gear sounds.

I like both setups a lot all of it is low wattage gear or set low as in the renegade and we have more than headroom to get the job done and then some. This weekend we are playing a rather large venue so I here they are pulling out the dual/triple rectifiers and some type of Marshall head and want me to bring my Deville 410. Sounds like its going to be a ear plug show for me.
