What's on the workbench?

Not my thing but well done on the Purchase!
Purchased the original for one of my mates circa 2010, he loves it!
The Crash, $1.40 AU to $1.00 US, purchased a lot back then!
Shouldnt have any problem with resale!!!
If I remember correctly, they are splined pots & the knobs were stuck to top face of the enclosure.
Some careful wiggle & pulling got them free!???
