Up for sale is a Dunlop High Gain GCB-80 in excellent shape.
Fully functional with smooth, consistent volume response. The rubber surface shows light signs of use, but nothing that affects playability. The protective plastic on the bottom plate is still intact, as shown in the photos.

The GCB-80 delivers a clean, transparent volume sweep without tone loss. Its durable metal chassis and reliable pot make it a solid choice over lighter or more fragile volume pedals - ideal for players who want long-term stability and consistent control.
No box.
