I have a 3u rack case with my GK MB Fusion and a Korg PitchPro tuner. Into the case also goes my microphone, speaker cables (already connected to the amp), channel footswitch and even my guitar stand (one of those little wooden ones). Whilst I lose some of benefits of the lightweight amp, the convenience and protection to the gear are well worth it. To echo someone else's comment above, I'm not entirely convinced about using the PitchPro yet - both from having to turn my back to tune up, and also, frankly, it's just not as good a tuner as my Sonic Research, but again the convenience and practicality are winning me over. I have short power cables for the amp and tuner plugged into a two-way to which I've attached a short lead and power socket and velcroed to the inside of the case. I then use a standard kettle lead to run to power (kettle lead stays in the rack too),
