I'm in the same boat. I have the Boss GT-1000 Core and am barely scratching the surface. 90% of the time I'm on a patch with comp and preamp only. The other 10% has some fuzz. I keep thinking I should sell it to someone who'd make better use of its capabilities and replace with discreet pedals, pedalboard, PSU etc. But then, it's going to cost a lot more than I'd get for it even if I just replace with the Boss comp, tuner and Pre.
