I have the GK 1001RB-II. I want to get an amp bag to protect it since I gig once or twice a month. GK has a bag for it but I am wondering if one of the rack bags would be better. I have never rack mounted anything in my life. Any thing I need to be aware of? How many slots do I need? What other items might I want to rack mount at some point? Tuner? Power conditioner (do I need one)? Preamp? I dont use any effects and I dont see a real need for them for me if that helps. Thanks all!
