Ambient Machine

Ambient Machine After lots of different incarnations, I‘ve come to set the basis design-wise of these pitch–bended cassette recorders with a delay stage. The cassette players may vary and have different quality or features (line in, radio, etc.), but all Ambient Machines have the same basic controls (pitch mod + delay with mix, time and… Read More

Casper Electronics Echo Bender

Casper Electronics Echo Bender The Echo Bender is a mix of multi FX pedal and noise maker that can process external signals or create complex sounds on its own, from warm analog sounding echo, to highly adjustable distortion, ring mod style feedback or noise generator. These modes can be used on their own or it… Read More

Modified Cassette Recorder #2

Modified Cassette Recorder #2 A birthday gift for Lauri, the cassette model used for this unit was originally sold in 1991 and it still runs like a charm. It comes with a built in mic in mini jack and was modded to add a pitch control, a pt2399 delay module and a requested 6,5 mm… Read More

Modded Tape Recorder

Modded Tape Recorder I modified this cassette recorder that already had a pitch control and added a second one. This gives you more playback range as you can go both fast or slow. It also has a pt2399 delay module with mix, time and feedback controls. Read More

Lo-fi Terror Noise Synth

Lo-fi Terror Noise Synth This noise machine is a collage of ideas all put together in a rush: a 40106 polyphonic oscillator section with starve control that goes through a galactic fuzz and a dirrrty delay section. It is not the cleanest build around, but it is nasty, edgy and capable of otherworldly alien sounds. Read More

Dirrrty Delay

Dirrrty Delay Extremely lo-fi and nasty delay pedal, based on a modified pt2399 delay board. The addition of delay time and feedback control to the existing circuit pushes the chip into wild oscillation territory, allowing the pedal to function as a standalone noise instrument as well. It is an easy mod with very few components,… Read More

Deep Blue Delay

Deep Blue Delay The Deep Blue Delay from Mad Professor is a natural sounding digital/analog delay based on the pt2399 chip. It is is specially designed to work well with distorted tones, but also has some surprisingly clean repeats. This version has an additional switch to allow infinite feedback. Here you'll find the veroboard layout… Read More

Mid-Fi Electronics Clari (not)

Mid-Fi Electronics Clari (not) Based on the noisy PT2399A chip, this crazy pedal from Mid-Fi Electronics is a delay/fuzz/vibrato/modulation/unstable tape simulator/weird noise thingy that brings that cassette lo-fi vibes and strange modulated echoes. This version is modified to include a switch to turn off the fuzz, leaving you with a clean weird noise thing if you… Read More

Noise Bomb

Noise Bomb This pedal is a continuation on the Noise Ensemble circuit, taking the pt2399 abuse to a new level. It basically adds controls for delay, delay time, gain and echo, making it even more noisy and weird. Still it is a relatively easy build, find the veroboard layout here. Read More
