Guyatone Guitar Pickup Amplifier GPX
The Guyatone GPX Guitar Pickup Amplifier combines an equalizer and overdrive in a single pedal, intended to shape the signal from a guitar's pickup before it reaches an amplifier. Its overdrive section adds gain and saturation, with a control that adjusts the amount of distortion or drive applied to the input signal. The equalizer section provides tone shaping, allowing the user to boost or cut specific frequency ranges to alter the character of the overdriven sound or to compensate for the pickup's natural response. The pedal's effect on the sound is to increase harmonic content and sustain through the overdrive, while the EQ can tailor the overall brightness, midrange presence, or bass response. The exact control labels and their specific frequency points are not detailed in the available data, but the unit functions as a signal processor that modifies the guitar's output before it reaches the amp.

- As of this posting, there may be now one piece of information about this on the English-language Internet. When I saw this pop up on ebay, I knew it would be mine.
- Good Points: For about a year, I've been failing with my mixer to setup a "Blend" knob between two separate arms of a feedback loop. Here, that's cake -- stereo delay L to Auto-Wah to Piezo, delay R to Filter to Mag pick up. Seamless shift from your Delay+T-wah loops to Delay+FX25, or blend them in whatever ratio your noise-heart wants. I love that the dial clicks into place at noon. Add to the blend a five-band EQ and Level knob, and this pedal will rule your loops with impunity.
- Bad Points: Unfortunately, the pre-amps, for noise-making, are an obstacle; neither is transparent. The Piezo is closest, with some added rusty nails and icicle teeth. The Mag input rolls off highs fairly dramatically, but it doesn't suck. Both of those EQ characters are workable, and they do interact well, but something makes your sound feel flatter, more paper-like. Might be compression, or loss of really-highs and -lows. If you use a jawa-line of distortion after, it may not matter. I don't, so it makes me sad
