The pedal it'self is very sturdy and the craftsmanship is top-notch (internally and externally). The pedal has input/output jacks, a 9v power jack (standard Boss), and an effects loop send/return. The switch turns the loop on/off and the knob has a 25k pot that controls the volume of the signal from the effects loop (I leave it wide open).
The big difference it makes, of course, is the sound. I cant emphasize this enough - the Jerry buffer makes a HUGE difference in the sound of the guitar in relation to the feel of playing. The high and low notes especially. There's a clarity to the high end that is totally new to my sound, I didn't realize how much high end resonance I've been missing. Also the low end feels tighter, and the notes come thru crisper and with more body. Honestly I could not have imagined how much tone I had been missing until I A/B'd my rig with the waldo-buffer - the difference is profound.
Kudos to Waldo! A super cool guy with a super cool product. I am very, very happy with it and cant imagine my sound now without it!
