I'm quite new to pedals and have recently discovered the joy of Rangemaster type pedals. My prior experience was only with a tubescreamer and a Boss SD-1. I never consistantly liked the tube screamer and the Boss was the best I knew of until I hit the current batch of boutique pedals. I'm using my Lovepedal BBB07 in Rangemaster settings and I find the pedal just so much more natural and organic sounding than either the TS or SD-1. Maybe it's because my ears are relating to all those old Les Paul/Marshall tunes from the 60's and 70's. So I was curious - are there major design differences between a TS or SD-1 pedal and something like the BBB07?
