The whole point of a Klon is pretty much the opposite of "oh, definitely a Klon, couldn't do it any other way". Instead of layering its own sound over the top of your amp, a Klon acts like adding a channel to your amp with a bit more gain than your base sound. It isn't a purely clean boost; there's a bit of low end roll-off and a subtle mid push that seems to enhance the base sound without getting overly bass-y as a clean boost can. Klons have more gain and volume than you'd ever want, and the mid push increases as you turn the gain up, so it's pretty easy to find the sweet spot for just about any amp. I spent 15-18 years looking for a boost that acts like this before I plugged into a Klone for the first time, and I'll never go back.
