With a classic five valve preamp configuration and a fully-loaded power section consisting of 4 x KT88 output valves, the CTM-200 is easily up to the job of delivering its powerful tones at small to medium-sized gigs night after night. From mellow 60s bass tone to growling 70s-style bass, straight through to thick and powerful modern tone, the CTM-200R covers a huge range of sonic ground. Hit the Mellow button to engage smooth, warm, clean tones or punch it out to dial-in pure valve overdriven growl. Standard tone controls give you a wide range of uber-musical sounds, while Deep, Mid Shift, and Bright switches let you fine-tune your tone to the situation. The EQ section is a passive tone circuit - meaning if all controls are at zero there will be no sound through the amp. All the controls are highly interactive, giving you the possibility to dial in exactly what tone you want. Dont be scared to dial the pots all the way to get the most from the controls. Saving and time consuming trips to the Tech and keeping your amp sounding better for longer, the CTM-200R features user adjustable bias for both output valves which can be set by engaging the bias mode of the dual function VU meter on the front panel. Each output valve is individually fused and user replaceable without removing the unit from its case meter also indicates valve or fuse failure. To get your tone direct to the desk in the studio or on stage, the CTM-200R features a valve-driven, transformer-derived DI output with an isolated ground to deliver maximum sonic purity and consistent output night after night. Similarly, the front-mounted effects loop is also valve-driven for maximum tonal preservation.
