I don’t subscribe to the hype that the Klon circuit is some sort of Magic Tone Box.
I think you could get the tones with a good many mild overdrives with tone controls.
However, the circuit is good at what it’s trying to be, and really good at cutting out a lot of the fiddling trying to get something else to do it.
It’s not trying to be a dedicated OD. It’s a background sweetener. I have distortion pedals but nothing that sweetens it up like that.
Between this and my Squishy Octopus, it almost sounds like I know what I’m doing.
I do find that it can pass as a decent full-OD with the Ultra-Drive Mod on. If I could have fit any more pots in there, I would have moved that to a second stomp switch with a drive pot. It gets nice, but if I didn’t want to use separate distortion pedals I’d want some adjustment.
This is why I bought two of the PCBs. 🙂
The font looked a lot clearer in Illustrator. At least I finally had different knobs that work out.


Barry, I am really, really thankful that you moved to onboard pots. I love those or 9mm pots, but the spacing just wouldn’t work for those on this one.
I’m looking on the bright side: that means I could arrange the pots any way I wanted. And at least I managed to hide half the mess under the board.

I had a DPDT board made up and placed, and found out I mismeasured by like 2mm and the plug hit it. Oh well, went old-school. Switch with the stock 47k soldered to one side, and sockets on the other. Have a 10k in it now.
This was the circuit that dipped into my precious scant 1n34As. I keep trying to save those.
I actually had this half-finished before my phaser, but had to order a couple capacitors I didn’t have and nabbed a handful of Russian D9B and K diodes. I’ll be experimenting with those, too. I’ve seen a couple people swear by D9Es in Klones, for instance.
