From the post
Info about the original from Catalinbread:
The CB30 is designed to give you jangly, dynamic, responsive overdriven tones, just like it's British 30 watt counterpart. The tone controls work exactly the same way as the actual amp, where the more the treble and bass increase, the more scooped the mids become, making it capable of being quite hollow and jangly. The CB30 can be dialed in for that immediate attack, compressed mid range honk, finished by the shimmery high end jangle, an elusive sound for many players. Like all the foundation pedals in our line it sounds excellent on its own, or when stacked with other pedals (no really, just wait until you put a treble boost in front!)
As owners of the real deal know, the amp has an amazing touch sensitivity, with the ability to go from clear and chimey, to that unique overdrive character with just your picking dynamics. The CB30 has the same response, and cleans up extremely well with your guitar's volume control. The CB30 is true bypass, and comes in a rugged silkscreened case, has black aluminum knobs that feel great, and are easy to see on stage. If you're looking for an expressive, chimey overdrive, we think you'll enjoy the CB30 for years to come.
