I got a GK 400RB head ( I guess late-80), and i wanna know which rack kit can fit with this one ? does the actual RB rack kit (400RB-IV, 700RB-II...) fit with this first generation GK ?
I bought some aluminum 90* stock from lowes and cut my own rack ears for my Backline 600. I have it in a cheap SKB case with a furman power supply. Its a 4 slot case and the 4th slot is probably not usable due to the ears not being exactly right, but it works and cost me like $8 plus an hour or two of cutting and drilling.
Gallien Krueger 400RB rack kit ?
