I just bought another Klon. I really like my Klon its gold and has no horse I've had it a while and its a really good pedal for me. I just picked up another one. It's silver and has a horsey on it and says S 390 on the board, whereas my gold says 3099 on it's board. I didn't know they made them in Silver. Has anyone seen them like this before? I've seen Gold with a horse and silver without one. But not silver with one. Any history on these things anywhere? I just got it so haven't had a chance to really A/B it against my original one yet. Also the components I can see through the gloop look different compared to my old one. Could any one offer any advice on these two units?
