and demand

true, although there seems to be a tendency in the realm of guitar
pedals that it does not seem to be insanely off for not too niche
things, with some exceptions. Well, maybe this is one of those. Or I
underestimate it. But some multi FX have a lot more going on inside,
compared to a looper.

Yeah, the mechanics part tends to be a tough one DIY wise, with those
mostly-metal things. That's why I toyed with the idea of repurposing
cheap momentary switch pedals ad connect them to a box that's not for
stomping on it.

I guess before I'd go to the trouble to use an RTOS on something like
the PI I'd be more inclined to use the somewhat familiar stm32f4, the
devboard that has a decent amount of RAM on it, and IIRC even an audio
codec, but I don't think I'll really have time for that, even though it
would be fun to implment something like that exactly the way I want it,
and not with the quirky / economical UIs those things tend to have.

Anyway, thanks for your reply.

The only exception is if they’re dumping old stock that’s already a loss - better to sell at a loss then than never sell at all, and better to stay in business long enough that the losses are offset by profits.

The catch is that any company who tries to sell a product for too much will be surprised by the Behringers of the world who are willing to make a product as cheaply as possible and get closer to the cost of the components than their competitors. Nobody can predict the future with 100% certainty, and there’s always the risk that what gets manufactured will not ever sell, at least not the entire inventory.

But unless you have experience with mechanical engineering, you might stomp on your baby a little too hard and then there’s no warranty.

The price is only vaguely bounded by the component costs. There are just so many other costs that aren’t inside the box that you receive. I don’t want to discourage you from trying to build something yourself, but you’d be surprised how much difference there is between the cost of what’s listed on the schematic versus the total cost. For one thing, the exact same parts can vary by 10x or more just based on how many you buy, whether it’s 1 or 1,000,000. But maybe you can figure out how to make a $1,000 gtr looper that sells for $200.
