This was a fun build! I breezed through it in a hour or so one night and realized it isn't that complicated. Great sound. The only trouble I had was drilling the 125B. Not sure what happened but I had the jacks too low close to the switch so when they would go in, they wouldn't fit all the way. So I put it into a 1590BB since I ran out of 125B's. I used an iRig Pre to hook up an SM57 to my iPhone and am able to get some very surprisingly good quality recordings (just so it's not my phone mic anymore). Here be pics!
