Weird cap placement and wiring suggestions

Yeah, those diagrams make sense to me. But in the darkglass setup, the volume and blend are passive, before the preamp, and the preamp is single-input. So they keep working fine when the pre is switched out of the signal path. With the artec, the balance/blend looks like it's passive, and the two wires from it are probably signal and ground. But the volume is part of the preamp circuit, not separate and passive. I don't think you can just change the pot values. That'd make the pre not work right IMHO.
Now, you could pull the volume out of it's hole, set it to full, and tape it so it doesn't move. (or swap in a trim pot.) Wire in a passive volume like in the darkglass diagram. That'd work, but you're still without a tone control. (And you'd have to somehow fit an extra pot in the back of the cavity.)
That seems to be the real issue--you're short a control spot to put a tone control. You could get double-stack pots. Fat Bass Tone has a 50K/250k that you could replace the volume and also have a tone. You'd also need stacked knobs.
So here's the choices I see:
1. Passive blend, with or without double-stack volume/tone.
Use the blend as "Input" on the switch. Run that to the tone control (assuming you do the double stack thing) and also to the switch. The Effect Send goes to where the blend connects now, the OUT connection on the artec board is "Effect Return". Wire the other half of the double pot to the volume wires on the artec. With all that, you can go passive, but volume will be always full on in passive.
2. Make it more like the darkglass.
Use a pot inside the cavity to force the artec into full volume, but wire in a passive volume before the preamp. (basically the diagram above.) Optionally, get a double-stack 250K/250K to add both passive volume and tone. Feed those into the switch.
3. Stay active.
Yank the ineffectual switch and call it a day.
4. Find some other preamp that does what you want.
Downside: $$$
5. Just go passive.
Easy, Cheap. Can reuse the existing blend knob.
I'd probably do 4 or 5. You do you, though.
