This is an easy pedal to use, it has a level, gain and 3 band eq as well as a mid scoop switch. T-Rex makes great quality pedals and this is no exception.

If you have 5 pedals, this is so simple to set up it's insane. Comes with all the cables you'll need, stick some Velcro on the back, plug it in, 2 minutes later you've got a perfectly quiet pedal board.
I love its simplicity, range of sounds, the fact that is REALLY QUIET, and sounds really good. If you're in the market for a chorus/flanger pedal, you should check it out, you wont regret it.
This Distortion Pedal has got three knobs to adjust the sound. The knobs are "Gain", "Tone" and "Level". The sound includes varieties from trebly bluesy settings with low gain to fuzzy warm heavy distortion.
The Tonebug Overdrive, by T-Rex Engineering, is a well-made, noise-free, easy-to-operate pedal.
The unit itself is very easy to use, depth, speed and level knob. Seems kinda standard on vibe pedals.
