For those after a command center for boutique tube amp tone with an array of controls and ironclad build, take a look at the Pettyjohn Electronics PettyDrive Deluxe Overdrive. Crafted on a dual channel design which can operate independently or in tandem, you get a clean boost/low gain bump in one channel and a medium/higher gain sear on the other which can be stacked in any which way you please. Throw in additional sculpting with low cut and clipping toggles and you've got a command center of overdriven tone.
