Finished the SDD-3000,lots of gain to be had and the pre and post makes it flexible, it's a nice boost, still prefer the klon tho.
Another flavor to be had.Build docs at Aion electronics under Eclipse.

Modded the C6 cap on the 4558,cause I didn't have a 4.7pf I was going to use a 10pf but decided to go for a 0.0033 and it gives a fuller boost it got more body, more full range I like it better, if you want more highs use a smaller cap but like I said for higher end I have the klon.

My advice for anyone building this is use 15V for power.It is good on 9V but could be excellent at 15V.I didn't have the pump needed for the higher voltage so I used the MAX.
