I built an ABY splitter from a different company about a year ago. It has a Dual IC buffer option, which I opted for. Sounds great, no loss when using it (with the Dual IC buffer that is, if built without it, it did suffer some loss that I could tell... maybe it was all in my head, but I could swear I heard loss.) anyway, I would love to build a version from PedalPCB, as I am sure it would be amazing!
