The quest for a solid-state guitar amplifier that accurately and reliably emulates a tube amp ends with the Peavey TransTube Series. TransTube technology emulates the sound and feel of tube amplifiers through a special design that took three U.S. Patents to cover. The TransTube preamp tailors the gain level for the desired amount of drive and the power amp responds with natural compression that increases with the amp's volume. The result is a line of amplifiers with widely ranging dynamics and natural "grit," just like a real tube amp.
