I love Klons for certain types of guitar and amp combinations, but like anything else, they have their applications and limitations.
This post isn't to say the Klons, the Klones, etc, aren't great.
They are. I got a KTR for my son a few years ago as a birthday present, and he uses it in every show.
Here's the application that, for me, works best with the Klon: I find they work best with single coil pickups and Fender style amps (I realize you use yours with the HDRX and your Bernies, showing once again how different we all are).
I've felt this way since they were available new, and was a Fulldrive user instead of a Klon user for a long time after trying both. The Fulldrive worked for me with 'buckers. Granted, they're very different pedals and they do
very different things.
But that's good, and not bad, because there are different applications for everything. I feel we need to temper our advice considering how different everyone's personal rigs can be, not to mention personal tastes. There isn't a pedal on the planet that works equally well for every amp and guitar. Or for that matter, every player, to say the least!
Since my son is a Fender player and endorser, I got him a KTR.
Nonetheless, for me it really is "Horsies for coursies."
I found a few pedals that give me low gain dirt without sounding like Klons. I'm not going to tout them, because my tastes and style aren't shared by everyone.
