    I&#x27;m totally loving amp modelling and convolution reverb using PiPedal <a href="https:&#x2F;&#x2F;rerdavies.github.io&#x2F;pipedal&#x2F;" rel="nofollow">https:&#x2F;&#x2F;rerdavies.github.io&#x2F;pipedal&#x2F;

      Here is my i5 NUC touchscreen audio cyberdeck running DietPi + PiPedal.

      This thing is awesome and I&#x27;m never wasting money another guitar pedal again.

        What is the DAC resolution and sample rate? Delay&#x2F;jitter? Noise?

        What&#x27;s the cost of something like this? It&#x27;s just the NUC and the USB Audio Interface? When I play through my Komplete Audio interface and my laptop I (think?) I notice a delay. How would that compare to an off-the-shelf multi-effect modeller? In cost and features&#x2F;performance.

        These have always interested me but not enough to actually do something ;)

          The NUC was used and just cost me a replacement fan. USB audio interface was cheap from online classified. The touchscreen was just over a $100 on AliExpress, plus a bunch of cables of various sizes and angles to connect it all.

          I&#x27;ve done the bare minimum to get this all going and haven&#x27;t done any optimizations. Sampling at 48kHz. Load is about 5-6% even with a complex effects chain. I don&#x27;t notice any latency, but I haven&#x27;t measured it. Latency isn&#x27;t an issue for the experimental instrument I play. The electroduochord.
