POP: Programmable Open Pedal, first test

First recordings of POP through a Fender Blues Deluxe 40W A/B tube amplifier. Camera is a GO Pro HERO. The amplifier is looking towards the wall in order to save our ears. Guitar is a Yamaha Revstar 420, I love it.


Sound quality looks promising, though still I can hear some computing noise, specially when configuring a compressor or a distortion/overdrive. When using delay type effects, or reverb, noise is quite bearable.

I am using a 512 bytes buffer, and getting around 20ms of latency, still too much.

Some more research is needed to get the best from this unit, keeping in mind the limitations: CHIP board works at 1GHz, and sound card is integrated in the SoC, as long as I know.

Stay alert for new tests.

I have also still to publish some documentation about the project. More details can be found here:

Please leave any feedback you consider relevant or funny.
