Cleaver Boost

From the vendor

Controls

• Volume – Controls the output volume

• High-Gain (toggle switch) – Increases gain

• Treble Cut (toggle switch) – Reduces treble

Specifications

• Onboard Voltage Doubler – Runs on standard 9VDC pedal power, internally steps supply voltage to 18V for increased headroom

• Designed for a 125B enclosure with top-mounted jacks
