I’m planning on buying an Axe Fx within the next couple months, and the bassist in our band has an Orange OB1-300 rack head. We are both looking into building some racks for live use, but neither of us know anything about racks. Some questions I have (please answer for both regular electric and bass if possible where needed): Are most rack units one size fits all? Could him and I buy the same rack and my axe would fit mine and his bass head would fit in his? What are some other essential rack items to go with your rack head? Obviously a power amp for the Axe (also looking for good suggestions on one of those) but I mean other rack accessories. What are some good brands/rack models for decent prices? We aren’t looking for anything huge and expensive. I’m sure there is more but I can’t really think of anything, anything else I need to know please feel free to tell me. Thanks for the help!
