Hmmm...I've never looked at stompboxes...any suggestions on where to start?
Seriously, there's a plethora of stompboxes coming out of China these days that are utterly jaw-dropping, both in capabilities AND price! Fave brands are Aural Dream (especially their Breath Delay and Super Ring), Rowin (I've got PILES of these), Joyo (their "white flanger" kicks the old MXR AC-powered ones out the window, and their high-end stereo boxes are to die for), Cuvave (FUZZ!!!!!!), Sonicake (great little things, super-clean), Mooer (more high-end), and on and on.
Much of this is going on on Amazon, but my personal go-tos out there seem to be the Brantford Pedal Mafia up in Ontario, with their cross-border inventory making sure the US users get the same free shipping as their Canadian customers. Check here on Reverb: https://reverb.com/shop/andrews-gear-depot-553 and on eBay: https://www.ebay.com/str/music4pros?_trksid=p2047675.l2563 LOTS of stuff to sift through! And the prices are such that you can haul off a bushel of these little widgets for as much as some high-end devices.
One other more "pro" device that's worth having if you're going to dive into pedals is this: https://www.sweetwater.com/store/detail/TriParMix--electro-harmonix-tri-parallel-mixer This thing is basically abuse potential turned into hardware! Just a look-see at this will give you ideas for weeks. It convinced me so strongly that I put together a parallel system for the studio's rack FX processors, using a Studio Technologies 1->8 stereo distro amp and a Rane SM 26B splitter/mixer for the summed return.
