Thread update.
The keyboard player in my band recommended a local metal fabrication workshop to me.
I had a chat with the boss and he seemed keen to help me out, so I took along a side from a 400RB-I with rack ears, and a side from my 400RB-II which didn't have rack ears.
The sides on the MKI and MKII are NOT interchangeable. I explained what I wanted, which was sides for the MK-II but with the addition of rack ears like the ones on the example MK-I sides.
Anyway, I collected them today, and it's worked out well.
Here's a few pics, and I must say they are looking rather sexy in their matching SKB Roto racks.
Cheers,
Rob
