The Varsity Reverb is a 15 watt class A tube amp that runs off of two EL84s and two 12AX7s to give it a nice bright rounded tone that has a ton of color and harmonics. The 12AX7s help give it a nice bright rounded American tone while the EL84s give you all the harmonics you need. Pair that with a tube driven 4 spring long pan reverb this this is amazing for any aplication. The NFB switch applies negative feedback to open up your tone and cleans it up. Really widens the response. This is a Varsity with a special Cathedral front which looks amazing.
