Fuzz
Rail
The Rail by Pettyjohn Electronics is a full-range fuzz machine designed with a unique approach to generating fuzz that does not rely on clipping diodes or vintage transistors. Instead, the pedal boosts the signal with extreme levels of gain into the voltage rails, hence the name "RAIL." The pedal features a streamlined control set with four knobs to adjust Level, Gain, Lows, and Highs, providing a vast range of fuzz and distortion tones. Key Features: \- Versatile, full-range fuzz and distortion circuit with tones for everyone \- Unique 8-way rotary switch sets the gain of the circuit \- Unique INFINITY gain setting that features a musical gating effect and the highest gain fuzz \- Buffered Level control for no tone suck or loading with other pedals \- Re-designed LOWS circuit that sweeps from 30Hz to 1kHz before the GAIN stage, interacting with the fuzz \- Re-designed sweepable HIGHS control, with a wide sweep from 22kHz down to 1 kHz, shaping the harmonics content \- High headroom with internal doubling from 6v-18v power input \- Draws under 100mA \- Quiet bypass relay-based true-bypass system for quiet switching \- Handmade in Oregon, USA \- New enclosure by GORVA design \- Top-mounted jacks The pedal operates with a dual rail doubling power supply, which can scale from +/-6v to +/-18v, affecting the headroom, tone, and feel of the pedal, achieving up to four times the headroom over standard 9v pedals. The internal supply mirrors the input voltage applied via the external power supply, allowing for experimentation and customization of the character of the distortion and fuzz as well as the output level. The Rail is suitable for use with guitars, bass, and keys, making it a versatile addition to any musician's setup.

Iron MKII
Gold MKII
The Gold MKII by Pettyjohn Electronics is a full-range overdrive/distortion pedal designed to capture the classic tones of the Marshall Plexi (1959SLP) in a compact pedal format. It features a proprietary 36V internal headroom power supply, providing an amp-like tone and response from a standard 9V power source. The pedal offers a wide gain range inspired by vintage Marshall tones, ranging from low-gain overdrive to full-on distortion, and is known for its amp-like feel and dynamics. The Gold MKII boasts a powerful 3-band EQ with wide-range, sweepable low cut and high cut filters, as well as a sweepable mid bell. It also includes two internal mini toggles for further tone shaping. The first toggle controls the hi-cut, allowing users to switch between a punchy modern feel and a smoother, vintage vibe to the highs. The second toggle adjusts the pedal's headroom, offering a choice between an open, amp-like feel resembling classic Plexi tone and a low headroom setting capturing the attitude and character of the iconic Klon overdrive. Additionally, the Gold MKII features a gain bypass in the third position of the headroom toggle, allowing users to completely bypass the clipping section and use the pedal as a formidable preamp with a semi-parametric 3-band EQ capable of sculpting any instrument with its 20Hz-20kHz frequency range. The pedal is handmade in the USA, with dimensions of 2.75”W x 4.75”L x 2.5”H and a weight of 2 lbs. It is designed, forged, and wired by a small team of partners at Pettyjohn Electronics. For more detailed technical specifications and custom shop options, interested parties can visit the official Pettyjohn Electronics website or contact authorized dealers.
