It's not true bypass, can't be (IIRC)... Been a while since I looked at the docs.
Wait a tick...
Nota Bene the last para.
From the Aion doc:
"The original unit uses the standard BOSS flip-flop bypass. The Blueshift has been designed to use a stomp switch and opto-FET in a configuraton that allows you to choose from two different bypass options. The first method mimics the signal path in the original, while the second method only passes the signal through a single op-amp buffer before splitting it into effect and output.
...
The stock bypass option mimics the signal path of the original circuit, with the signal passing through pre-emphasis and de-emphasis filters.
The minimalist bypass option splits the signal immediately after the first op-amp. The bypass is still buffered for the stereo output, but the signal only passes through that single op-amp buffer.
Since this is a stereo-splitting effect, I’ve intentionally not accounted for true bypass. Passive signal-splitting can be very problematic unless you know what’s going on in your signal chain. With that disclaimer, you can probably wire it up as true bypass without too much trouble as long as you have a 4PDT stomp switch—but you’re on your own if you do! I haven’t tested this and it is beyond the scope of this documentation."
So, it can be true bypass if you get down and dirty with it.
Been building up confidence to do this build, and wasn't sure which bypass to do, so I bought two sets of PCBs (before there was a Wazacraft re-issue, and I can't remember why Behringer wasn't an option at the time either). When I first got the Blueshift PCBs, I tried to suss out a couple things:
1) A way to route the jumpers to/from a switch so that I could have both stock and minimalist bypass together (managed to do so on another project, so thus emboldened I thought...).
2) A way to wire up the suggested untested-DIY 4PDT for true bypass.
Well...
Thing 1 was, I'm pretty sure, impossible, and I gave up.
Thing 2 didn't get a full-press effort because trying to do Thing 1 had caused permanent neurological damage to the synapses in my grey matter — Frizzle-fried, I did not get to shake hands with beef.
Now a friend wants me to build him a Blueshift so we can compare it to his Wazacraft...
