Let us know how it performs. I have the 100w MK1 and it's a beaut. I have one channel for clean, one blues, one really dirty and one funky setting. I left the 'panel' on a setting with a good clean tone so I can play around with the other effect options and pedals.
** One thing I learnt and have tried is to turn the master volume right up and use the gain and pre-volume to adjust the tone and volume levels. It gives a much better overall tone.
