I picked up an LPB-1 because hey, it was cheap. It actually does provide a very nice sounding dark boost when you play lightly, I really like it's sound in that manner. But I mostly play very hard with high output basses which cause the pedal to fuzz out a bit. But some people, I thought, might find that tone useful so I recorded a clip of it.
For this clip I'm playing a Fender Mustang Bass with a Seymour Duncan Quarter Pounder in it through the LPB-1, somewhat dead roundwound strings, fingerstyle, and the tone on the bass rolled down a bit. There's a lot of pickup clunk, which some players would like, I know I don't, but for that somewhat rocky clunky overdriven tone, this pedal isn't too bad for 40$. Here's how it sounds:

I can't do any more clips of this with the Precision pickup because the bass has been mudbuckered, but if anyone would like to hear clips of how it sounds with a Dimarzio Model One I could do that as well at some point. Or I suppose I should do some with some lighter playing with the pedal on/off so you can see how it affects the sound. Let me know if you want to hear anything else, and let me know what you think!
