Great 100 Watt Combo from 1973. Similar to a Fender Twin Reverb but in my opinion better! The tone stack is Fendery but has an additional Mid control Stack that is separate and much more effective. Massive Reverb! The Reverb Tank is driven from an EL84 directly with no transformer.. massive sound.. really good (and I have recently repaired several Fender Twins but prefer this! A great amp and can be had very reasonably.
