The RR Amps Fat Drive is able to provide a transparent boost or a harmonically rich overdrive.
It loves to take a tube amp that is on the edge, over the top!

Inspired by the Klon Centaur, but given it’s own twist, it not only excels as a boost into a crunchy amp but it now also delivers stellar overdriven tones. The Level control has a big range to get you a massive output that will push any amp into big fat overdrive. The Treble control is flat at 12:00 but allows you to fine tune by either adding or subtracting high end.  The Gain control can get you anything from a clean boost in the off position to a big rock tone when it’s above 3:00 and everything in between.

Price is 199 euro.
