Walter is still around, but he only makes the piezo buffer, not the headphone amp.
Whatever the bass related product, if Steve could make a buck or so on commission, he was all in hyping it up. Even if he wasn't an authorized dealer. Most of those products were good, but regardless, there were always a bunch of members ready to jump on any bandwagon he started.
Last time I checked, a couple of years ago, Steve was working on a ranch in New Mexico. Now he says he's a certified Level 1 ski instructor at a resort about 25 miles south of Taos. Whatever, I hope he's found himself.
