I acutally have one of these that I don't use at the moment but won't let go of because I like it a lot.
It's great for that classic fuzz sound. Think jack casady
, when he blends the fuzzed out amp with a clean amp. Not that there is a blend but it's reminiscent of that sound he used to get with that technique. It has really solid bottom (most Frantone does) IMO. The only reason I do not have it on my rig is because it can get lost in the band mix of my current project. For the right gig/project, this is a great fuzz and this is an AMAZINGLY LOW price. If you're even curious, I'd snatch it up. They went for $340 new and Fran is no longer in business so it's now "vintage". Hope that's somewhat helpful.
FYI- there used to be a demo online but it looks like someone took it down. Sorry, I tried to dig it up for you.
