- Build Rating
This is my second build of the AionFX Tachyon Amp Overdrive, based on the lead mode of the Boss SD-2. My first build was about two years ago. In a decluttering frenzy, I foolishly sold the first build, and later wished I still had it. I recently built the Angry Charles hoping to scratch the itch (only because I already had that enclosure finished and drilled for the Angry Charles pot layout). The AC didn't really do it for me, so here we are with Tachyon #2.
This worked on first power-up, and boy am I glad I took the time to build a second. This thing absolutely rips. My first build had a somewhat wonky tone control; the tone control on build #2 works absolutely fine. I triple-checked all the component values on build #1, thinking I must have used a wrong one. I either managed to miss it after multiple checks (wouldn't be the first time), or I had a "correct" part that was out-of-spec. Either way, no such issue with this build.
Build #1 was a lot neater, both on the inside and outside. For #2, I'm using the buffered electrical bypass scheme. I used too-short wires between the Aion board and my bypass board, that's why it's sitting at the ugly angle. There's a piece of double-sided foam tape between the bypass PCB and the footswitch. On the exterior, it's another faux snakeskin with envirotex. I did a sloppy job with both the glue I used for the snakeskin, and it's also a lousy epoxy resin job.
But anyway, it sounds a million times better than it looks. I think this circuit is going to get a custom PCB treatment.
Highly recommended!
