DOD Studio BiFET Preamp 410

The original DOD units had "balanced" XLR output as well as the normal 1/4" jack and no footswitch. This has been adapted for stompbox use and could work well with acoustic guitar.

  5. I'm built this circuit and I'm guessing It amazing! Clean tone and good eq. For testes, I used 15nf intead 22 nf to get more mid-bass
