This is the Grid 1 Audio amp made by Kevin Frazier. It is 60 watts through 2×12 Eminence Tonkerlite speakers. It has an analog reverb using two Belton chips. It sounds like an overgrown Deluxe Reverb. Warm, sweet and lush sounding. There are two 1UF tubes with digital power amp. Oh yeah……it’s battery powered too!!!!
