LPB-1 is a classic simple boost pedal used to add gain to the signal to help push your amp into clipping, and/or boost your volume for solo's. It doesn't do so much of the "Buffering" like a unity gain buffer would. LPB-1 is not a unity gain pedal, but a pedal adding gain to the signal. If you are looking to "buffer" your signal, then Waldo's buffer would be my recommendation, and exactly the circuit you need to achieve the Jerry Garcia buffered tone. I use to use a LPB-1 and do still depending on the amp I use for certain purposes, I prefer to use an OD pedal with an active EQ to boost my signal in my Jerry rig. If you are looking for a simple boost pedal for solos, the LPB-1 is great for that.
