This is my second Aion rift build. I had the first one in a 1590BB with a battery option, which I almost always used because running it off of wall power was noticeably noisier. Going with the 1590B this time, there was no room for that so I just slapped on a simple power filter and it comes out exactly as clean as battery power. I absolutely love these pedals and it’s very rare that I can think of another fuzz I’d rather use. Thanks Aion for the super in-depth documentation, high-quality pcb, and fast shipping as always.
