April has come again and almost gone, as usual life gets more and more crazy it feels like. With so many irons in the fire, surprise expenses, and family emergencies I wasn’t able to make good on my original plans (my apologies) or do a demo this year but I did manage to squeeze in a special build. I give you the (A)SD-1 for world autism month ( or whatever it’s being called now, seems like there is a new label every year
.)
I try and do something a little different and out of the box every year for April and this idea spawned from an on going conversation with @Guardians of the analog about the 808 vs the SD-1 and trying to convince me to build an SD-1, he finally succeeded. I was about to order an Uber drive pcb and then I realized I had an extra dwarven hammer board in the pile which would save me a few bucks (one of my favorite PPCB projects, and the OD I seem to always return to.) it hit me that I could build an SD-1 on that. These two are inherently related and the schematics are compatible with a handful of mods and component value changes. Almost like a SD-1 geared towards more “modern metal” types tones. It was feasible and a reasonable gamble since the HPF has the stock value of 47n in there so I have access to the original circuit.
The shift in Frequency response change , and asymmetric clipping I found I like it more as a lead boost, more than for a rhythm, (at least with my rig) where the Precision drive gives you a tight and cutting rhythm tone the (A)SD-1 gives a fuller less compressed response, it doesn’t cut quite as much bass and shifts the mid boost to about 1Khz making it ideal for a fatter more present lead tone.
All in all a niche build, despite the versatility I’m not sure very many would be into it. Here’s a quick clip of how I use it.
