I'm selling this because I unearthed it from an old effects pedal case. I'm currently storing a different TS, so I'm putting this one up for sale. I've confirmed it works with a 9V power supply. Since I can't compare it to a new one, I'm selling it as-is, with no returns or exchanges, regarding any crackling or noise. The Ibanez Tube Screamer is a green effects pedal with Drive, Tone, and Level controls. - Brand: Ibanez - Color: Green - Model Name: Tube Screamer - Controls: Drive, Tone, Level - Connections: 1/4 inch jacks Thank you for looking.
