This model is now discontinued and is a very valuable item. I also own the successor model, the OD-FIVE 2 explosion, but the sound is different from the Extreme. This one has a wider range of sound creation, with an amp-like sound, while the explosion gives the impression of an easy-to-use overdrive/distortion effector. I've switched to digital, but I'm still hesitant to sell it, so I may remove the listing. A multi-functional, handmade distortion pedal. - Model Name: OD-FIVE 2 Xtreme - Function: Handmade Distortion - Controls: Level, Bottom, Shape, Boost, Gain - Switches: ON/OFF, CH. - Output Terminals: OUTPUT, INPUT - Brand: oval tone Thank you for viewing.
