Hi guys,... I'm building my new live rig rack, which will also be used a lot at home at very quiet volumes,... I have an FX3 and so far I used it with 2U Matrix gt1600fx and 2 Friedman 412 cabs,..... but now I got myself Fryette LXII to replace the Matrix. Since Fryette is getting quite hot at times, I'm not sure if it would be smarter to just keep it in the separate 3U rack and leave a space below and above it, and put FX3 in a separate 3U rack,... or get a 4U rack and keep them together. Would the heat hurt my brand new Fx3 Turbo? And if kept together in the same rack, would it be better to put fx3 above or under the power amp? This ism my first trip to rack equipment, so Im not sure,... Im used to amp heads and 412s.
