This is a Maxon Tube Screamer. The main difference from the famous Ibanez TS9 is the bypass. This Maxon version has true bypass, which is less likely to negatively affect the sound when creating a clean tone, allowing you to purely incorporate the Tube Screamer sound. It produces incredibly satisfying sounds. It's a Tube Screamer, after all. Great for the front pickup of a Strat, of course. The rear humbucker of a Les Paul sounds amazing, almost like it's going to jump out at you. It's a used item, so it has a well-worn appearance, but it works without any problems. Thank you. #Maxon - Brand: Maxon - Model Name: Overdrive - Color: Green - Number of Knobs: 3 - LED Indicator: Yes Thank you for looking.
