THD BiValve 30 Guitar Amp HeadTHD
For sale is a great tube amplifier head from THD. This model is the Bi-Valve, the bigger brother to the very popular UniValve but with two output tubes instead. As with the UniValve, this amplifier is self biasing and can accept nearly any tube combination between the preamp or power tubes, giving you almost endless tube combinations to experiment with. Tonally this amplifier goes from sweet and subtle cleans to massively aggressive overdrive with thick and rich low end. It's built-in Hot Plate power attenuator allows for full output distortion at almost any volume, and the unique combination of THD's touch-sensitive input circuit and the wonderfully active and reactive tone control make for a front-end that really responds to subtle and not-so-subtle changes in the signal. Currently this amplifier has a set of Russian Electro-Harmonix 6v6gt power tubes that have a nice classic American tone to them. Cosmetically the amplifier is in great condition, with very little sign of play or wear. Included with this amplifier is a carry case and tube retainers. This is a great studio amplifier, with tons of tonal versatility and an excellent gigging amplifier as well.
