This is a set of effects pedals: the BEHRINGER TO800 and the electro-harmonix EAST RIVER DRIVE. Both are well-known TS-type overdrive pedals. The ERD from Electro-Harmonix, in particular, has a wide range and is easy to use, in my opinion. I think it can be used as a standalone unit or as a gain booster. Please ask any questions about the condition or request additional photos in the comments. First come, first served. - Model Name: TO800 - Brand: Behringer - Model Name: EAST RIVER DRIVE - Brand: Electro-Harmonix - Color: Green Booster Overdrive Distortion Effect Pedal
