From the manual...
The Twin Tube Classic is designed for years of solid performance. One of the secrets is the duo of type 6021 tubes. These sub-miniature triodes represent the pinnacle of tube technology advancement. The 6021s were designed and manufactured to meet the MIL-E-1 spec for reliability under conditions of severe shock, vibration and temperature. They provide extremely long service life with virtually no tendency towards microphonics (see USA Department of Defense Standards, Test Methods for Electron Tubes). Also, unlike some “tube” stomp boxes that only use the tubes as a clipping diode, the Twin Tube Classic employs a 100% vacuum tube signal path with a high voltage power supply. This allows the tubes to operate to their fullest potential and provides the most gain and the smoothest tone. The result is the classic tube sound, smooth distortion, and low order harmonics you expect from a great tube preamp.
