Found a busted up Yamaha VSS-30 Portasound at the Thrift Store.
After spending all day and most the night bending this little devil, we now have a new noisy toy in the ProBurn studio.

Modifications: 8-port patch bay, Overdrive knob, Speed hack button, 8bit switch, FM switch, Mallet switch, Sample hack buttons

Schematics and bends by: Nikki Telladictorian

Special thanks for lending a hand: Dave 8Cylinder, Greg VanEck
