This is a single-speaker guitar cabinet from Electro-Harmonix. I purchased it used and have used it for live performances and recording, but I'm selling it now to clear out some gear. There is some rust and dirt from use and age, but it functions without any problems. It's equipped with a Celestion Sidewinder speaker, which is now difficult to obtain. The model number (S12-150) indicates a 12-inch, 150W, 8Ω specification. I used it with a 100W head amplifier. When recording, it had a better boxy sound than 2x12 or 4x12 cabinets, and the recorded sound was good. I think it can be used immediately with a KEMPER or similar. Please refrain from purchasing if you are overly concerned about condition. #electroharmonix #guitarcabinet #elehamo #celestion #sidewinder
