As a guitar player who's not a gear collector, and in particular not a pedal-head, there have only been a few pedals that have a) gotten my attention through the chatter and b) made the case for actually being useful and not just neat. When I started 20 years ago, it was Tube Screamer replicas and the new wahs, with photo resistors instead of mechanical ones. Around the same time, the DD-6 was super versatile but also very simple to use. Five years later, it was the Dano minis, which were cheap and fun and fit the music I was into at the time. Then it was the loopers, culminating with the ditto. Other than that, the rise of true bypass registered with me, I tho I never pursued the mods, it's something I consider when making a purchase.
I'm currently excited about some Strymon products, particularly after seeing Mark's demonstration of their Leslie simulator, which is a sound I've been looking for for at least a decade (pity the souls who got caught buying previous attempts at a Leslie faker--they all sound awful). We'll see if my interest sustains, or if this is just a flash in the pan.
Have we reached peak pedal? It's already a tiny niche in an ever dwindling market. There will always be lawyer guitars, and there will always be lawyer amps and pedals. There will continue to be interesting innovations.
