Dual source Acoustic IR pedal

Guitar Pedals
1

Here is my pedal project

It is a pedal for acoustic guitar with piezo pickup (and built-in mic).
All the processing is based on CMSIS DSP library

  • It provides two kind of FIR filters (quackless and mic-like)
  • EQ shape (17 stages IIR)
  • EQ tonestack based on Fishman mini amp
  • A dual source feature with Baggs Anthem-like crossover.

Interesting project!

I think you’ve got your footswitches reversed, they should be:
FS1 : 25 (LEFT switch viewed from above)
FS2 : 26 (RIGHT switch viewed from above)

Can you post a photo of your Stereo mod for Terrarium?
(Edit) I found photo of the mod on AGF. Very nice!

Thanks for that veroboard layout - I might try this on my Terrarium.
I was puzzled by the extra resistor… then I remembered… phantom power!
