This Spaceman Saturn V - Harmonic Booster is a handmade dynamic boost and a transparent, touch sensitive low gain overdrive with a unique sound. It is a great pedal if you want push your amp into natural edge-of-breakup sound. It also works great an an always on booster at the beginning of your pedal chain as it cleans up remarkably well with a guitar volume and plays very well with other dirt pedals.

The pedal is a part of a limited edition and is in an excellent used condition. Unfortunately, I do not have the original box and manual. 

The pedal runs off 9 volt battery or Boss style power supply. 

Thanks for looking.
