i've finally managed to track one of these down for a damn-i-might-aswell-buy-it-now-or-i'll-never-get-one price
sample and hold is bitchcoat, just like this:
and the envelope filter sounds like Ed O'Brien rocking out on his Lovetone Meatball during 'Talk Show Host'. fan-fooking-tastic!
there's a significant drop in volume when either mode is engaged, which could be an issue. i wouldn't be suprised if there was a volume trim pot in there, and we'll see how it behaves pre/post dirt and other buffered pedals etc over the coming days.
but i'm extremely happy with the sounds, and the fact i'll probably be using it in a dry/wet bypass loop (or parallel signal path) anyway, means the volume drop might not be so bad.
