The PE-5 is a pedal designed for bass guitar and upright bass which incorporates a sophisticated 5 band EQ and also offers superior function as a Pre-Amp, Direct Box, and signal booster.The PE-5 is engineered with a unique switchable input impedance which allows the pedal to match exactly to either a magnetic or piezo pickup. It achieves the full band spectrum for either pickup source. In addition it is a signal booster which compensates for low output pickups and will also provide ample drive for any amplifier. The input level and gain controls are designed to precisely match the pickup output to an amplifier. The line output is strong enough to use directly into a power amplifier or a powered speaker.The 5-band EQ is a high precision equalizer which means that each boost or cut level is identical to each adjacent band. Plus the Q factor of each band is identical. This makes it far easier for the player to accomplish the tone that they are pursuing. These frequency bands were carefull
