If you could up the numbers I think you would have a market for pedals looking like that
Thought about it, even did the sums as an alternative for when my job inevitably goes to India and they decide I'm too expensive. The problem is to actually make enough money out of this you've either got to come up with something incredibly simple (Meathead/SHO) as the huge mark up then doesn't seem too bad. Or, you've got to charge massive money for them. Enough so that expectations are raised beyond our meagre production skills.
Raw materials aren't the issue. There's about £50 of stuff that goes into a pedal like the Sholicon. Which would be fine if I could knock one out in a couple of hours. The problem is that, even with all the bits and life not getting in the way, it takes about a week end to end. Given what I get paid for sitting at a desk and hammering away at a keyboard, and the fact that it's not just me that'd need paying, the price I'd have to charge to quit my day job would be astronomical.
So sadly no, it'll have to remain a hobby I'm afraid. There would certainly be a market if I could knock them out cheaply... But boutique pedals made by one-man-bands are expensive for a very good reason.
