[QUOTE 4201775, member: 259"]Nice - I think you could do sound on sound on those, so they were a much sought-after item for DIY home studio bands in the 80s.[/QUOTE]
I used mine with the inputs and outputs crossed over to make a pretty basic echo machine for my Korg MS 10 synthesiser. When I was a student, they were used to good effect every time the Scottish man mountain of a self proclaimed 'stud of the house' brought home a girl for rumpy tumpy. I'd give him a few minutes warming up time and then I'd power up and play 'Scotland the Brave' with the echo, VCO and ASDR envelope selected for maximum contra bonking effect.
Oh how we laughed.
