This is my main head for my Jazz rig. This head takes 6L6 tubes, and is 70 watts. This amp has an amazing, warm tone. The head has always given me a clear, crisp tone. But remember that this head is old, and will not give you a bright tone. I find this amp is made especially for jazz players, or even blues players. I used to pedal all my overdrives through it to play Pop/Punk, but later found out that this amp sounds the best when just played straight. I use this for my cleans in my studio, because this amp hits my ideal tone right on the money. I recommend this amp to anyone looking for a straight, warm clean amplifier. The only thing I would get done to this amp is get it serviced, It's had some miles put on it.
