Not my thing but well done on the Purchase!
If I remember correctly, they are splined pots & the knobs were stuck to top face of the enclosure.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!!!
