Here's a short tune I wrote while testing this great fuzz stompbox. The signal chain for this video was: Fender American Standard Telecaster/LTD MH-1000 NT - PiodFX Tone Keeper - Mesa MKIV revision A head channel 2 - Mesa 4x12 OS cab - Shure SM57 and AKG C414 B-ULS - RME OctaMic II. I totally love this stompbox, it's huge fun to play and it reacts on each instrument so vividly - with Telecaster I had that Grand Funk Railroad feel, while with humbucker equipped guitar (in this case LTD), I instantly recalled Chicago's "25is6to4" lead tone. I even used it on bass, parallel with the clean signal.
