Valeton Dapper Bass multi-effect pedal, like new, $100.
Includes tuner, boost and compression, envelope filter, preamp/amp simulator with EQ and gain controls, octave (which lets you control the mix of your dry signal with notes one and/or two octaves down), chorus, and an effects loop. There are multiple output options -- a regular ¼" output to plug into an amp, a parallel output for running your un-effected signal into a separate amp, and an XLR jack to connect directly to a PA or recording mixer.
Includes original box, power supply, and manual.
Here are links to two different YouTube videos demonstrating this pedal. The first is two and a half minutes and just shows someone playing through the unit, with no talking. The second is longer, a little over 17 minutes, and gets into more detail about each of the effects and some of the possibilities for combining them.

I'm in Gill, but willing to meet elsewhere if we can find a mutually convenient location and time.
