Is it another Tube Screamer derivative? It could be a little of all of those but it isn’t and we have no clue how to describe it other than it is freakin killer. It sounds great through every amp we played it through and it sounds great with all styles of pickups and guitars. Buuuuut, we know everybody needs that reference so the best we can do is tell you it is very smooth, chewy and cuts through a mix. You can play country, rock, jazz or blues and it maintains an amazing feel.
