that mantis sounds quite a bit cleaner, nice.. judging from the youtube that is

and they even sent me a nice infosheet,
supporting products from 25+ years ago, not bad indeed

MK2, the copy was a bit messy but i think all is readable

MK1

ill have a try tomorrow, when there's more light in my room;)
apparently there's a mark 1 and 2 version of which i have both schematics..
got the pedal too, nice, tho bit lowfi

i still have the original schematics somewhere, mailed carlsbro a few years ago and they sent it, any interest for that? could make a highres photo
