From Jackson Audio:The overdrive circuit of the BROKEN ARROW is a soft clipping overdrive circuit designed in the same vein as the venerable TS-808. The distinction between the TS-808 and the BROKEN ARROW being that there is no set “mid-hump” in the BROKEN ARROW and the tone is relatively flat when all controls are set at 12:00. Given that the BROKEN ARROW features an active 3 band EQ, there was no need to force a mid bump unnecessarily as a mid bump is easily achieved by increasing the MID knob.The overdrive portion of the BROKEN ARROW is a completely new way of using and adjusting overdrive! With 4 clipping diode presets and our innovative GAIN CYCLE feature, the BROKEN ARROW will make most other overdrive pedals obsolete!Input Impedance: 1MOutput Impedance: 100kPower Supply: DCVoltage Input: 9V MAXPolarity: Center NegativeMax.
