Great use scenario for the Slampegg, Microtube Variety: having an (Ampeg mini 2x10) amp into which I'm plugging via pedalboard, but while not wanting to mess with any knobs on it. It was set for room conditions in a live-band recording session.
So I got to use my Barber Linden EQ as sort of a bass tone shaper, then the Slampegg as a proper preamp to sculpt that sound into something that would first sound punchy and funky, then next song, something deeply dubby and, well, literally dub-depth reggae, then after that, something tight and progressive. All on my trusty Mustang PJ, which has a lot of tone control of its own.
The guy running the session kept turning me up because he liked the tone so much. Can't say much about the quality of performance or anything, but using Ultra Hi for song one, then Ultra Lo for song two, then just getting tasty with the knobs on song three... if this pedal's v1 of the Slampegg series, then I'm jealous of y'all cats with the latest ones. Sucker is a complete beast!
Though not to be outdone, last week I took my pedalboard with the Particle Accelerator to a jam session, and couldn't help but feel that my new Kiesel Aries 6-string bass might have a special bond with it. Something about how it treats mids even with that knob left at 10/flat... it was a really really really fat tone.
