The GT BASS is a 300w all tube Bass Guitar head powered by 4 KT-150 Power tubes and 3 12AX7 Pre-Amp tubes and is Hand Built in TEXAS. It features a simplistic classic design with massive power that will push an 810 cabinet to pure thunder. This amp provides a warm, precise, and transparent tone with unmatched clarity thanks to being built around premium Mundorf and Takman Audiophile grade components, Toroidal transformers, and Mil-Spec control pots. Like the 200w Dynamo GTS Guitar amplifiers that first debut in 2011 NAMM show, the GT BASS carries over DNA in its design for power and clarity driven by a F-2b/1x style tube pre-amp with a classic TMB circuit after listening to input from a variety of Bass Players to build the ultimate Bass rig.
