initial test of a modulated PT2399 circuit…
a breadboard version of some PT2399 modifications i’ve been working on. there are a lot of DIY schematics that utilize the PT2399 (Magnus Modulus, Echo Base delay, Rebote, etc.). i’ve

PT2399 build…
this is an older build now, but i wanted to post it while i’ve been on the subject to record the process. believe it or not, i still have some
the Stirgiform PT2399 delay…
two days worth of soldering and layout. it’s a combination of the Magnus Modulus and Rebote delay schematics. i couldn’t get the mixing circuit to really work from the Rebote
Arduino: second verse, same as first… sort of
well, not really. feeble attempt and making some sort of microprocessor controlled tempo clock, but a good exercise in the ATMEGA328s finicky behavior. don’t ask me what that squeal is.
PT2399 with BJT preamp
here’s a short clip of the delay circuit that i intend to convert to a stomp box. i’m still working out the kinks in the pre-amp stage to solidify the
fuzzy PT2399 on baritone guitar…
Here’s a loose guide that I’m using to migrate the PT2399 into stomp box world. Here’s a dry run sample with a Gretsch Baritone guitar. [audio:http://abrammorphew.com/notes/wp-content/uploads/2011/06/pt2399_guitar_delay.mp3|titles=pt2399_guitar_delay]
Square-wave Oscillator Meets PT2399…
Square-wave Oscillator with PT2399… from abram on Vimeo. Very short video of the waveform captured using Xoscpe of the PT2399 applied to the LM386 square-wave oscillator. Sorry for the bad
Bending notes with PT2399…
i’ve been experimenting with this PT2399 chip and using various schematics to create a digital delay circuit. the delay time seems to be directly attached to the sample rate since
