Switchblade delivers the full spectrum of sonic goods from spanking clean to a raging scream. It is the multi-specialist from funk, rock and pop to metal. Catering to players across all genres, its four channels and three independent effect sections serve up the widest range of sounds we have ever combined in a single amp. Programmable potentiometers enable settings to be stored in 128 memory slots, and the included MIDI board affords easy access to these presets at the touch of a button. Simply dial in and save your tone – building a sound library has never been so easy.
All Switchblade models are also available with TSC, a built-in tube technician. It automatically biases the amp to extend tube life, shuts down defective tubes to get you through the gig, and indicates ratings to make tube selection an exercise in convenience. TSC even lets you operate EL34 and 6L6GC tubes simultaneously.
Available since 2006, Switchblade amps with and without TSC have won a loyal following across all genres. Many regard it as the most significant advance in tube amps made in the first decade of this century.
