Zach is a great guy. I bought an SHO ages ago, played with it for a while, and emailed him with a comment about how much I liked it. Fifteen minutes later I get a one sentence response...
"Okay, but what does it DO???"
At first I'm thinking, what an arrogant little nimrod! And then the humor of it hits me, he wants ME to tell HIM what HIS pedal does. So I write back with my best explanation of what the thing does. Another fifteen minutes later I get a three paragraph response about how the ultra-high input impedance is like peddling your bicycle with the chain removed, along with much, MUCH more bizarro techno-babble. He then ends by saying that he has to go to the grocery store, and gives me his cellphone number just in case I have any more questions.
I've been a fan ever since.
He's one of the few people out there trying to do something groundbreaking in effects pedals, rather than "design" the newest, hippest, most expensive Tone Bender/Fuzzface/Big Muff clone in a fancy-schmancy enclosure. Yep, they're expensive. And worth every penny as far as I'm concerned.
