Aion Prism

The Aion version of the Boss FA-1. Got through this quicker than I anticipated. Cool one. Lots of clean boost with the bass and treble at noon-ish, or boost/lower bass & treble with those knobs.

Nice!!!! Where did you find the HA1457s?
Thanks!
Small Bear:

I'm planning on trying a few other ICs but I haven't yet. The build docs say:

"Either use two HA1457Ws in IC1 and IC2 or use one 4558-style dual op amp in IC1-2. I recommend socketing all three so you can experiment."
 
Thanks!

Cool! and Thank You! The FA1 is on my to do list. I like to build the older circuits as close as I can to their original specs. Its time consuming and sometimes risky to get the old op amps, but Small bear is a safe bet. So looks like I will need to order a few!
