I was trying to find a jog wheel for my mb-seq4 and wasn’t finding anything I liked. I’m using wilba’s front panel board. I found a jog wheel that fits the encoder on this board perfectly. It’s the jog wheel from an Akai MPC1000 and it was pretty easy to find from parts suppliers online (around $6 USD). You can get them in silver or black. I just thought I would share in case anyone else was looking.
Wow!
This gives me the vision of some new “MPC1000 jog wheel bulk order” topics

You just need the red plastic sides and you’ll have an “optimus prime” MPC-style MB-SEQ!
Heheh, exactly what I thought - it has written “Transformers” all over - but it is a really nice color combination, well done!
