Wharfedale Proverb is a very nice reverb. I had the chance to play with a demo and it was very good. I will say it was better than my M300 but not as good as
my MPX550. So like other Wharfedale stuff its a very big bang for the buck
I've been selling them for $285.00 shipped and everyone loves them.
