I was a big pedal head but like others here I've learned over time how much a pedal chain sucks desirable frequencies out of your tone and I now use the amp settings and guitar volume to shape tone alot more , regardless of true pedal bypass in my experience your never going to get the best out of a good amp when you've got a chain running into it, however saying all that l do use keeley pedals esp the time machine or Java boost pedals as well as his compressors, I reckon he's made some amazing pedals though not so blown away with his more recent creations - got the skreddy supatone recently and of all the fuzz pedals I've owned I reckon this one is beautiful, it has a guitar/bass toggle switch that can put you into much deeper tones, it's got killer sustain and alot of flexibility compared to the bulk of other fuzz pedals out there, the skreddy echo is am incredible pedal also, his pedals are well worth checking out, pricey but worth it if you want to get it right the first time
