The tones are tuned for a great all-around boost, right up to a low gain drive on the A side, used primarily on the neck pickup. Side A features the famous Royal Blue overdrive pedal, and side B is a fat, dynamic tone with a certain power amp response with plenty of headroom. Side B is a completely new design and is primarily used as a bridge pickup. That's how Matt uses his Supreme pedal. Whatever type of guitar you prefer, with one flick of a switch you can fine-tune one side for your neck pickup and the other side for your bridge pickup, giving you a tone optimized for that pickup. Both sides feature a highly versatile EQ section with treble and bass controls for optimal results. Another use for the Supreme is to play with a single channel amp and use one side for rhythm tones and the other for more voluminous leads. It has two different gain and volume levels and lets you switch from Side A to Side B with a single flick of a switch. In other words, you can easily handle two channels of completely separate EQ/gain/volume and switch between them without using a complicated programmable switcher. The fun doesn't end there, as you can also stack both drives in independent mode. Stacking the drives gives you an even wider range of tones that Supreme offers. Supreme in stacking mode is perfect when you want more gain and compression. It's up to you to decide how best to use Supreme, the ultimate guitar overdrive pedal.
