All i can say is wow..it is all the buttons i would ad to my marshalls to dial in. Main reason was to make my clean jtm45 to bluesbreaker-light plexi gain..mission accomplished in spades..and radical radical high gain applications. Bonus..cleanest purest boost i ever had..was bumping everything on my board,not a pedal guy, got a Friedman Runt for the purpose of messing with my pedals. I did very careful research after learning my amp before to deciding to build on tone..instant EQ change allow for 3 dif marshall clean platforms under it. Have all my pedals out & homemade board apart..adding tier & rewiring for as many of pedals can fit, Always will use gain channels of amps but man is this fun to go from Modern metal to AC/dc to claption.to roots rock n roll by a few flips of switch..This plexi pedal def performs in the Marshall circuit & Friedman is the cleanest amp ever..not 1 dot of noise with this pedal screaming into it !! Its like having precise control of a plexs..variac & blend is so cool.
