For one thing, JHS makes mostly average clones, and there's an outsized amount of hype for what the pedals actually are.
For another, this follows a common and annoying pattern in my niche: for practically every comp pedal containing an optical component, they advertise it as being "just like the famed LA2A" or "just like legendary studio compressors that made all your favorite records". But obviously those pedals are NOT just like an LA2A or whatever. Just having a similar circuit design, or a similar component, or a similar knob layout, does NOT make the pedal sound like the original device.
I'd be delighted to find out this new JHS pedal beats the odds and isn't just a bag of hype.
