Each channel features independent gain, volume, and EQ controls for perfect tonal shaping. An integrated boost is included with it's own footswitch, and you can select either Pre or Post boost modes from the rear panel, with Pre boost allowing you to drive the amp model harder, with a distinct mid-frequency hump. Both the DI output (ideal for PAs, mixers, and interfaces) and the headphone output (ideal for silent practice) offer IR-based simulations of a Celestion 2x12 Alnico Blue cabinet, for the sound of a real vintage combo amp. And as a pedalboard-friendly platform, the DC30 Preamp will take drive pedals like a champ.
The AC30 has a distinctive British tube amp sound, with crunching leads and rhythm guitar and warm cleans. The DC30 delivers that same sonic character, now with modern enhancements for even further versatility.
However, if you prefer a more traditional stompbox experience, TC Electronic also incorporated a Bypass mode. Entering this mode allows you to simply stomp the pedal on and off, allowing you to switch between bypass and the channel used before entering Bypass mode.
Switching to the Pre mode repositions the booster before the amp modeler in the signal chain. This setup drives the amplifier with greater intensity, simulating the effect of a vintage tube screamer placed in front of your amp. This introduces a touch of grit and character, delivering a tasteful vintage-style drive. With either setting, you precisely control the Boost gain amount with a small trim pot next to the Pre/Post boost switch.
