Maybe it is yours. Got it from kid, who said he got it from someone else, about a month ago. Anyway the clean boost is nice. Great for adding distortion to the amp without altering the eq much.
The LPB-1 adds a tad of compression and it tightens up your sound.. less messy overdrive/distortion tones.. so even if you use high gain it will actually help to maintain the clarity of your notes.
