PT2399 Digital garbage generator and delay
This is the second iteration of our Crush Delay. It is an echo-delay unit based on the PT2399 IC, which although able to offer 400 ms of clean delay, has a special talent for generating digital garbage and noise! Our beautiful freak features multiple circuit bends to the chip, an FX send & return, and up to 2 seconds of filthy digital delay.
This model has been improved greatly from the first version with extensive signal routing changes to improve performance and extend its range of sonic possibilities.
The new Crush Delay features two VCAs to control the amount of signal sent to the delay. The first is routed to both the dry/wet mix and the delay, and the second directly to the delay. Combining the second VCA and the FX Send output allows for external feedback routings (see block diagram below).
The biggest improvement from the previous version of the module is to the control of PT2399 itself through the application of circuit bending techniques. It has an improved and extended speed control, offering a wider range and smoother control of the Crush section, converting this unit into a VC digital garbage generator!
It also includes three gate controllable switches to enable the three circuit-bends on the chip providing a high level of control over the digital noise, glitches and general nasty mayhem!
The VC feedback features an automatic gain control to keep levels stable at any feedback level.
Available as an assembled Module and as a DIY project.
