I used to own one. It was very good but I preferred some of my other pedals to it, and I got to AB it once with an original Klon and me and my friend both agreed the original was noticeably better. It was more organic, less stiff and just better. Obviously not worth the price though
These are the overdrive pedals that have been keepers and my favorites so far:
Airis Savage
Mad Professor Blue Sky
Maxon TBO-9
Mad Professor Sweet Honey
Jetter Gold Standard
Thorpy Gunshot
KHDK Ghoul Screamer
Thorpy Warthog
The Airis Savage, Thorpy Gunshot, and Jetter Gold are my favorites. I recently ordered a bunch more pedals by Airis but haven't gotten to try them yet, but maybe they'll make me sell some of my other pedals since I'm so impressed with his Savage pedal.
