Personally by now I have 3 kinds of pedals I like out of the whole market:
1. Selfbuild clones. Boosts, Fuzzes, comps and some other stuff. Fuzzes, comps and boosts can take central parts for me but a lot of this is trying stuff out any toying around.
2. Juansolo stuff. Anything I can't build myself (yet xD) and when I just need good quality for the most part. Great stuff, even better bloke. Will recommend to anyone who'll listen.
3. Strymon pedals. I am not aware of anyone who can clone these as they are hella complex and advanced (not that I have seen schematics though). Don't even know if they can be considered truly boutique in the way we often use it, seems more like high end gear to me really. Extremely versatile and amazing quality. Not cheap but I feel not overpriced, at least in my mind. For me these are insanely great.
Disclaimer: I am paid by neither Strymon, Juansolo nor myself....well maybe by myself. =)
Of course there are some other smaller things out there that strike my fancy, but nothing much noteworthy really. I do like my MXR 10 Band EQ for example. And of course the clones John or I build are based on things (though John brings a lot more selfmodding into it). There are also some other ones out there I would gladly buy like Devi Ever stuff. While I think they are a bit overpriced for example the Zvex stuff is pretty great. The Machine looks pretty innovative to me and the Super Hard On while insanely simple still is a pretty unusual and new way for a booster to work (though from what I read Vexter was only like the second or so guy to do it). So you got a booster which is a great circuit, pretty unique, but which is so freaking small and simple that it can be taped to the side of a push pull poti and build for peanuts, but sells for more than 100 quid in the cheaper version. All parts together this would cost me less than 10 to make. Deduct savings from bigger orders of parts, add labour costs and sum total I still can't see how over 100 quid is fair considering for how much other circuits go. Of course here we get into the discussion of what people are willing to pay will be charged and all that, I just wanne say with things like this I personally draw the line. If I pay a lot for a Strymon Timeline I can kinda see a lot more value for money.
Point I was trying to make at the beginning before I drifted off was that I don't find a lot of stuff where I feel like I should buy it because the price properly fits the product. Somethings I would gladly pay (Strymon, Devi ever, etc), some are ok (MXR, etc), but the largest chunk of things feel so overpriced, especially when you look at what it is, that I just rather make a clone or have one made.
