Handmade limited edition effects pedals
Welcome to Vorp FX, home of handmade, limited-edition effects pedals. This is my pedal blog, in which I show and briefly describe all the pedals I've built, with some notes about the build process. It also lists all Vorp FX pedals that are currently available to buy. Vorp FX is not a business, but one man's hobby, therefore the pedals are produced in very small quantities. For more information about Vorp FX, please see the About page.
This time it's not a pedal, but a diagnostic tool. After years of working with makeshift audio probes, I finally decided to build a proper one and also invest in proper hardware.

The Blandine reverb (named after Saint Blandina, patron saint of the city of Lyon, France) is based on the Timestream Reverb by deadastronautfx with a few minor tweaks by myself. The reverb circuit is built around the Belton brick, with an additional circuit that allows it to go into controlled self-oscillation for a nice ethereal tone. Requires a 9V DC power supply.

The Beta Preamp is inspired by solid state amplifier from the late 1970s of the same name that was rediscovered by several grunge bands in the 1990s. It is loud, sludgy and gritty and perfect for stoner doom tones. A 3-band EQ allows versatile sound shaping, and a voice switch improves the sound for drop tuning or bass guitar. With gain at maximum, this is LOUD. It is best used as a preamp to go directly into your power amp, but it can also be used as an overdrive/distortion pedal. Requires a 9V DC power supply.

The Astronaut is in fact the Chasm Reverb by deadastronautfx, assembled by myself and put in a box of my own design. It's a particularly nice ambient-ish reverb that can go into self-oscillation or just pleasantly hold atmospheric tones for long periods of time. It's pretty unique in what it does, and it's perfect for the ambient guitar music I'm playing. The knobs set the overall output level, the mix of wet and dry signal, oscillation on/off, signal damping (a low pass filter), and the length of the reverb decay. The combination of the Damp and Decay settings heavily affects if and how the signal will go into self-oscillation. No battery operation; requires a 9V DC power supply.

The Ampère Fuzz (named after André-Marie Ampère, who is also pictured on the pedal) sounds positively electric. It is a gated silicon fuzz with a lot of bite (thanks to a full low and high end) that is inspired by a somewhat obscure Chinese pedal (which may or may not be a rip-off of a different circuit) with a handful of modifications. Sounds robust with a low gate setting, sounds really freaky at high gate settings. Requires a 9V DC power supply.

The Bellboy is my take on a famous octave fuzz/distortion pedal. Below the 12th fret, it will generate distortion with some slight ring modulation; above the 12th fret it will generate a more pronounced fuzz and upper octave effect that adds a certain brightness to the tone. The soft/hard switch allows to adjust the intensity of both the distortion and the modulation/octave effect. Requires a 9V DC power supply.

I have become aware of a minor design flaw in most Double Dodo pedals with 3-way clipping switches and a serial number of DDOD031 and lower.
The flaw does not affect the regular operation of the pedal, which works just as it should as long as the clipping switch is in the SYMM or ASYM position. Only in the middle position, where it is supposed to completely bypass diode clipping and provide a relatively clean boost, does it add some faint asymmetrical silicon diode clipping and is thus not as clean, nor as loud as it should be.
This pedal was made in a very limited edition of three for April Fool's Day 2021, but it's not a joke. While none of the knobs are labeled, all of them are doing something; in fact, they are highly interactive and dependent on each other. You may like or dislike the things it does to your guitar signal, but believe me when I tell you that it's an experience that is not for the faint at heart.

The Espresso is an attempt to revive a rare fuzz pedal from the early 1970s that has achieved something of a cult following after it was used by producer/musician Steve Albini in numerous recording sessions. The sound is wild, chewy and abrasive, and has a very distinct flavour. At low gain settings, it merely adds compression and harmonics, but it quickly breaks into an aggressive fuzz tone with the gain knob around the 1 o'clock mark. The clipping stage can be bypassed with a toggle switch, which allows the pedal to be used as a compressor or clean boost. Requires a 9V DC power supply.

The Astrolabe is my take on the famous Astro-Tone Fuzz by the Universal Amplifier Company, first built in 1967. It was one of the first silicon fuzz units, developed in an era when germanium was still the industry standard. Requires a 9V DC power supply.
