Description
Based on a Plexi amp that is designed with more flexibility. Classic Plexi and JCM800 tones are at your command. Add a 3-band EQ for versatile tone shaping as well as a Presence control. Finally, there is a switch to adjust Gain structure. This is a harmonically rich overdrive that allows you to summon all your favorite Marshall style tones.
May the Rock Godz be with you.
