Based in Albany, Oregon; Pettyjohn Electronics pedals "are engineered and built in the USA without compromise or shortcuts" - in their own words. Founded by studio engineer Stephen Pettyjohn, the eponymous company uses analogue components almost exclusively in the design of its guitar pedals, for achieving the most traditional and authentic tones possible.
Pettyjohn's Filter Standard EQ pedal exemplifies this approach; a highly-effective semi-parametric equaliser that allows you to carefully craft the perfect guitar tone. Featuring 3 bands, you can easily influence the key areas of your guitar's signal, with up to a whopping 12dB of boost/cut at your disposal. It's fair to say that the Pettyjohn Electronics Filter EQ pedal offers the same flexibility of an analogue mixing desk channel strip, but in a compact stompbox format.
Here's what Pettyjohn Electronics says about the Filter Standard:
The Filter is a simple but powerful semi-parametric guitar equalizer featuring three individual bands to cover the range of a guitar effectively. The circuit has been carefully designed with high headroom for low noise, low distortion performance, while offering up to 12dB of boost or cut with the ultra transparency and musicality of an analog recording console EQ.
The low-band is switchable between a bell filter at 150 Hz or a low shelf at 100 Hz and has been voiced to provide very powerful low-end without feeling muddy, even at high boost levels. The high-band is a carefully voiced bell filter with a center point at 6 kHz or 4 kHz. The high-band filter is highly useful for dialing in the perfect amount of sweet articulation or smoothing harsh overtones with a touch of analog magic that console EQ is known for.
The mid-band is a tip of the hat to some of the most beloved console EQs ever made and features a premium inductor driven bell filter with three selectable frequencies at 460 Hz, 780 Hz and 1.8KHz. These frequencies are key musical points in the guitar’s range that can be very useful to control with a dedicated EQ.
Beyond utility value, the use of a real inductor results in a rich, dimensional sound that makes the “mids” come alive with extra harmonics, especially when pushed hard. Vocal, wah type tones are even available when the mid bell is pushed to the extreme and can be perfect for getting a solo track to cut through the mix. With plenty of gain on tap, use the level control knob to achieve unity gain or boosting with any EQ curve.
The Filter is a culmination of our obsession with studio grade electronics and we are proud to offer what we feel is the most musical EQ ever put into a pedal format. The Filter comes equipped with a top-self, Burr Brown OPA2134 opamp chip, chosen for its transparent tonal quality and low noise.
