Which volume pedal impedance would be suited for my use?

Hello,
I use a volume pedal to blend in an effected/overdriven sound to my clean "acoustic" sound coming from the Grace Felix preamp.
I've been using an Ernie Ball MVP for a while, but I don't really like it, mostly because of its large footprint, and unability to completely cut the volume at heel down (probably an issue of my particular pedal).
Since I'm out for a change, I figured it would be a good idea to try to figure out the best impedance choice.
My rig is built around a dual source system I installed in my acoustic guitars. The guitars have an internal "microphone" (not really a microphone, but it behaves like one. It's a peculiar design made by Dave Wendler, called "dynamic field pickup") going to one channel of the Felix, and a Sunrise magnetic soundhole pickup going to the other channel. I use one of the DI output of the Felix to send a blend of the two channels to the house.
I also use the amp out of the Felix to send the signal of the Sunrise channel to : volume pedal => pedalboard => tube amp => OX => house
So my volume pedal gets the signal from the Felix's unbalanced amp output, which has a 150ohms impedance. I would guess a low impedance volume pedal is the way to go, but being an impedance NOOB, I'd like someone more knowledgeable than me to give his input.
To be clear, it works ok with the high impedance of the MVP, but I suspect it might work better with a lower impedance model, like the Xotic 25k for instance.
Thanks!
