Used Roland all the way through my college years as we were endorsed by them, wouldn't recommend to anyone.
I've heard Genz stuff is the Bee's Knees so I'd go with that!

I got my SVT 6 PRO and 810 cab (all American) for £900 off of a reluctant middle age man who was downsizing his house and quite obviously his wife was forcing him to sell it, that was a steal as it wasn't gigged and was pristine!
If it falls through, I may consider the 3 hour drive down at the weekend!
