This is the rare one, the one you’ve heard of- and they surface one every couple years.

The Maestro Full Range Booster is an absolute sleeper of a vintage EQ and Fuzz unit. Absolutely great eq notches in my opinion, and the fuzz switch can go from amazing old school Sabbath vibes to absolute destroyer on the middle setting. The stock switches are fragile, and the fuzz switch has been replaced by a standard hardware store light switch. Somehow it now doubles the output in the center setting and it can absolutely decimate the front end of any amp. There is an internal 9v and it will not ship with a battery per USPS regulation- it’s an easy two flathead screw to access the inside.

- The 9v clip ground wire has been extended.
- The fuzz switch has been replaced.
- The on/off switch is bent but functions. It engages all or defaults to eq switch placement.

The unit has rust on the outside and is missing pant. It has dings and scratches all over. It survived this long, it will outlive us. I am downsizing my vintage effects, and this will be a house favorite at any studio, or right at home on your desk as a vibey preamp.
