Selling my THD Bivalve 30 Amp. In excellent cosmetic and working condition. Never gigged. Built-in THD hot plate attenuator. Can change out all kinds of tubes, and self-biasing. A lot of amp for the $$$. Price is firm at $650. A really good deal for this amp. Local pick-up in Annapolis. Will consider trades. but will be pretty selective (guitars, basses, amps; vintage stereo equipment; trade value around $750....a nice Fender tweed bassman combo would do the trick).
