Ashdown CTM-100 Custom 100w Bass Valve Amp Head

Meet the CTM-100, a powerhouse 100W all-valve bass amplifier that marries the timeless sonic essence of classic valve heads with contemporary construction and reliability. Designed to withstand the rigors of the road, this amp resides in a robust 18mm marine-grade birch ply cabinet, complete with heavy-duty flip-style handles and an internal fan to ensure optimal cooling during extended performances. Crafted with the finest components, the CTM-100 guarantees years of trouble-free operation, night after night.

At its core, the CTM-100 boasts a classic five-valve preamp configuration and a fully loaded power section featuring 2 x KT88 output valves, making it more than capable of delivering its commanding tones at small to medium-sized gigs with unwavering consistency. Its tonal versatility is unparalleled, spanning from the mellow '60s bass tones to the growling '70s-style bass and, further still, to the thick and powerful modern sound. A range of tone controls, along with Deep, Mid Shift, and Bright switches, allows for precise fine-tuning to suit any musical context.

The CTM-100's passive tone circuit offers a wide spectrum of musical sounds, with highly interactive controls providing the ability to dial in the exact tone you desire. In fact, cranking the pots all the way opens up even more possibilities.

One standout feature is the user-adjustable bias for both output valves, reducing costly trips to the tech and extending the life of your amp. This feature can be easily accessed through the dual-function VU meter on the front panel. Furthermore, each output valve is individually fused and user-replaceable without removing the unit from its case, and the meter also indicates valve or fuse failure.

For studio or stage use, the CTM-100 offers a tube-driven, transformer-derived DI output with an isolated ground for maximum sonic purity and consistent output. Additionally, the front-mounted effects loop is also valve-driven, ensuring your tone is preserved to the fullest.
