I understand the ethical question, but nearly every major manufacturer has a Tube Screamer, a Klone and nearly all fuzzes are either Big Muff or Fuzz Face variants. The Boss CE and DD circuits are also closely copied by many reputable manufacturers with minimal changes.
So what is it? Everyone has to be completely original? I can be down with that, but then a lot of "major" pedal lines will shrink considerably, if that's the standard.
Or, it seems, that each manufacturer tries to draw the line where is convenient to them. That's fine, but then be prepared for consumers to draw their own lines too.
I have to say that I ended up buying a lot of "real " pedals because I got a copy first to see if it worked for me. For example: I bought the Carl Martin Plexitone because I tried a Caline English Man first (which is an 1:1 copy of it) and ended up liking it so much, I decided to buy the real thing soon after , because I wanted the peace of mind for reliability. Would I have bought the Plexitone sight unseen? Probably not, but the Caline was cheap enough to give it a try and that end up resulting in a sale for Carl Martin as well and I love that pedal and recommend it all the time.
I've been using the Kliq pedal tuners on several boards here with 0 issues. I am sure it's not original. btw, who claims originality on a tuner? Because, except for something like a Peterson strobe tuner, I doubt the circuits are very different from one to the other, I mean, they all have to tune....
Another good example was the DOD 250 preamp. I didn't know I liked it until I got a Mosky copy with a balance I had on an Amazon card. Then I bought the original later. Turns out the Mosky sounded better too. Oops.
