FeaturesThe RASPBERRY BOOSTER by One Control is a unique boost pedal designed to increase gain boost while maintaining tonal details by controlling the fine textures of the outputted distortion. BJF designed this pedal to recreate the tone of a vintage boost/overdrive pedal driving an old school tube amp. Note: It's important to place the RASPBERRY BOOSTER at the beginning of your pedal chain in order to take advantage of the Z (impedance) control. Impedance can be effected by various factors.SpecificationsInput impedance: 9.8K to 319KOutput impedance: 25KDrive voltage: 9 VConsumption Draw: 1.5 mAS / N ratio: -80 dBSize: 39 W x 100 D x 31 H mm (not including projections)   47 W x 100 D x 48 H mm (including projections)Weight: Approximately 160 gTrue-Bypass SwitchingHigh Quality Aluminum EnclosurePower: 9V Battery or Standard DC Power Supply
