From the vendor
Controls
• Low Cut – Attenuates low frequencies
• Gain Trim – Controls the gain of the unit
• Level Low – Controls the overall output volume in Low Gain mode
• Level High – Controls the overall output volume in High Gain mode
• Gain Low (Internal Trimpot) – Sets the Gain in Low Gain mode
• Gain High (Internal Trimpot) – Sets the Gain in High Gain mode
• Voltage (Toggle Switch) – Selects between 9V / 27V operation
• Active/Bypass (Foot Switch) – Activates/Bypasses the pedal
• High/Low Gain (Foot Switch) – Selects between High Gain / Low Gain modes
Specifications
• Designed for a 1590BBM enclosure with top-mounted jacks
