Is there any stick bass, NS/Stick, or just bass oriented stick players on here that use the EBS Microbass 3? Or a similar two-channel preamp? I really like the tones you can get out of it from what I've seen, and it seems like a super versatile tool for signal control, especially if you want to play in stereo or with an A/B rig.

I don't have a stick instrument yet, but I am hoping to save up and get one within the next year. I am already considering getting the Microbass 3 just for my bass, but if a stick player can vouch for it, I think that will seal my decision.

StepAbout and SP2 are two popular choices here. The StepAbout is a premium product - be sure to check that out. The SP2 is a smaller option that will require a TRS and can split or run signal paths mono.

Looks like the FX out has an option to support stereo running TRS out, but I only see a single output, not the isolated dual mono outputs on the aforementioned pre-amps.

Next steps are to explore the routing diagram - with all my free time.

I humbly suggest the StepABout!! As far as routing and tone shaping there is NOTHING better. It is also very well built and sturdy.
