Hand-built in the UK Custom Shop, the CTM-300 delivers 300 watts of all-valve power through six KT88s and a five-valve preamp, offering everything from smooth ’60s warmth to roaring ’70s growl and modern punch. Housed in rugged marine-grade birch ply with heavy-duty handles, it features Deep, Mid Shift, and Bright switches, a user-adjustable bias with dual-function VU meter, and individually fused tubes for easy maintenance. With a tube-driven DI and front-mounted FX loop, the CTM-300 combines vintage character with modern reliability - built for bassists who demand uncompromising tone and power.
