Great sounding dependable amp.

This amp has a phantastic clean sound and a great, saturated and rich singing lead sound when the gain is maxed and the bass is turned down. It is a bit less perfect for crunch sounds in my opinion. The cleans are not as deep as a blackface Fender, but more stable and in the same ballpark. The reverb sounds classic and great. It is hard to believe that the amp has a hybrid design (solid state preamp, 2 x 6L6 tube power amp, 12AX7 preamp-tube driven lead channel); to me it sounds and feels like my all-tube amps. It takes pedals very well. The amp is loud and is able to cut through an 8 piece band with a Hammond organ and a horn section. The sound also does not get lost in an open air setting. I have been gigging with the amp for 35 years, and it is highly dependable, lightweight and easy to carry. It sounds great both with humbucker and single-coil equipped guitars. If you are a player who is happy with one great clean and one great lead sound, this is the amp for you.
