These are pedals that I have built for sale. Look at my shop to see if I have got any for sale, or get in touch and I can build a new.

Parametric Equalizer/Booster

This is a parametric equalizer that also can serve as a very versatile boost pedal.It has two frequency bands you can choose between: low (about 40-400 Hz) and high (about 300-3000 Hz). The boost/cut is +/- 15 dB. A JFET output gain stage adds an extra 26 dB boost. Works with 9-18V DC. You might […]

1458 Classic Distortion

This is an old-school, classic, opamp-based overdrive/distortion. It is perhaps closer to the Proco RAT, than to for example the MXR Distortion +. It goes from mild (kind of) overdrive to saturated fuzzy distortion. It’s built around the 1458 dual opamp (hence the name), which basically is two LM741. After being clipped in the opamp […]

Filter Overdrive (Systech Ovedrive clone)

The Systech Overdrive was made in the mid 70s by Systems & Technology in Music, Inc. in Kalamazoo, Michigan. Systech was a collaboration between Greg Hochman (Keith Emerson’s Moog tech) and Charlie Wicks (who founded Pro-Co, home of the RAT).It has a sweepable, Wah-like EQ, an MC1458 and hard clipping diodes. It’s a buffered bypass […]

Frequency Control Fuzz

This is a buzzy, gated fuzz with a very pronounced mid scoop. The circuit is inspired by the Shin–ei Companion FY-2. It has an extra output gain stage, so it can be very loud. And the best thing is that you can change the mid frequency from around 100 Hz to a bit above 1 kHz. […]

Fuzz Booster

This is a One Knob Fuzz and a Treble Booster in the same box. The fuzz is on the left (one knob, volume)  and the booster is on the right (two knobs, tone and volume). With the switch you can alter the effects order, switch to the left is fuzz -> booster, and switch to […]

One knob fuzz

This is a silicon fuzz. The only control is an output volume control. Adjust the amount of fuzz with the guitar volume. It doesn’t clean up much when you turn down the guitar volume. Like most fuzz pedals, it has a low input impedance and will sound very different if put behind a buffered pedal. […]

Treble Booster

A classic treble booster driven by one silicon transistor. The tone control let you adjust the frequency range from full and bassy, to classic 60s “mid-treble”. In this one, the level control is a standard post-gain volume control, which means the gain always is on max and it is a little dirtier. A different approach […]
