I have a DemonFX "King of Drive" KOT clone. And it's about as clone-ish as it gets right down to the Nichichon FG and Panasonic EQV caps. Who knows if the caps are real or not. The 4580's look legit to me, but wtf do I know
I do know that it's a GREAT sounding pedal and from A/B testing videos I've listened to very close to the KOT.
The DemonFX comes with the high gain mod on an internal switch.
In fact, it was this pedal that got me interested in trying to build my own pedal. In reading the bazillion interwebz threads about the KOT and it's clones exposed me to all this talk about magical fairy dust unobtanium diodes, 4 year waiting lists, "only 10 available on Wednesdays at 1pm Eastern", etc that I was intrigued.....then I found PedalPCB.com.....my credit card bill has been piling up just a tad faster than all these capacitors, resistors, IC's, etc at my workbench. (Yet, I never seem to have that ONE value cap for my current build and bam there goes another $35 order.....sigh).
So, there's a couple of different KOT clones out there that I "think" are in fact the same pedal as the DemonFX pedal. (68Pedals "King of Clone", 98Pedals "King of Tone" and a company called LY Pedals that goes so far as to actually make a counterfeit KOT.) The gut shots of all the above mentioned clones look like the same builder to me, just different branding and selling outlets. When I was looking for a KOT alternative the 68Pedals version was going for over $100 on Ebay. I saw the DemonFX version on Amazon for $59 so I snagged it since it was a low risk proposition.
I was thinking if I really liked it, I'd put myself on the AnalogMan waiting list or try to snag one of the elusive "Wednesday only" Prince of Tone pedals. Little did I realize I'd be building them myself and tweaking the heck out of them and be doing late night internet searches for NOS diodes hahaha.
Joyo has gotten into the KOT game with their new "
King of Kings" pedal. The whole Joyo "R" Series of pedals are clones but very good sounding and good build quality. I've played their Tauren (Klon), Tai-Chi (Zen Drive), Zip Amp (BB Preamp) clones. They all sound and look excellent but this was right when I started building so I returned them all (Yeehaw Amazon Prime baby!) and committed myself to learning how to build them all myself.
The DemonFX build quality is not as good as the Joyo R series pedals. The finish on my pedal is starting to flake off just sitting on my desk hah. I can't imagine it holding up very well for a real gigging musician. But it's been a decent tonal reference pedal for my own Paragon tweaks and satisfied a curiosity itch for a ridiculously hyped and unavailable pedal.
