From the vendor

Clone board of the smallsound/bigsound Fuck Overdrive. As strictly an overdrive, it is outstanding, with a really wide range of drive. From boost, all the way to raging overdriven amp tones, it covers all the ground. It's real trick is the sag effect, which when engaged, gives the effect of your amp blowing up, and melting down. The sag effect is actually envelope driven, and depending on the settings, the harder you play, the more "broken" the amp sounds.

This DEFX version has all the controls of the original circuit, plus an additional "Sag Depth" control, which adds additional fine tuning of the sag effect dependent on the amount of Drive and Threshold settings.

Version v.2 corrects the bypass error of v.1.
