Mad Professor Super Black has the Fender Blackface tone in the box! The whole amp signal path is replicated inside. You can turn your amplifier easily into 60 ́s Fender glory! Don’t be afraid to plug the Super Black pedal also straight into the return jack of your amp ́s FX loop. This way you can bypass the preamp of your amp and get the sound of a full Blackface amp signal path without the color of your amp's preamp.
