I've been trialing the Boss BD-2W and I've found this is the type of drive sound that I'd like to pursue. I like how responsive it is. Works very well with my amp set to break up just a hair. I find it maybe just a tad harsh in the top end so I decided last night to order the Keeley Super Phat Mod full range. Has anyone ever tired the Keeley? I ordered the Canadian edition which I assume is exactly the same as the gold version internally. What I'm hoping to get from it is pretty much the same thing as the BD-2w but smoother in the top range. The keeley is a little less expensive than the boss so I doubt its a case of one being better than the other.
