I've got one of these combos - great sounding, loud, punchy little amp with an awesome tone. Used to use this for monitoring on stage whilst taking a signal out to the P.A. Didn't really need to for volume but it helped with the overall sound balance with the rest of the band. We've decided, to minimise set up time, to just use the P.A. as a vocal P.A. and push the backline a bit more. The walkabout is more than capable of handling this increase in volume, but I decided I also wanted the extension cab that goes with this - pushes a bit more air, deeper tone, looks great and it's bloody loud! Big John had the extension cab for sale with this amp a couple of weeks ago on this very forum. I was a bit jittery about buying as the cab was in Belgium and i'd never imported from abroad before. I am pleased to report that the experience couldn't have gone better. Loads of communication and delivery within a week. If you fancy the amp, don't be put off by it being located on the conkinonk - Big John is a pleasure to deal with. You won't be disappointed!
