A compact 5-watt tube amp that captures the raw, mid-century Chicago blues and early rock tones of 1950s Supro combos. Driven by a single 12AX7 preamp tube and a Class-A 6V6 power tube pushing a custom 10-inch DK10 speaker, it delivers rich cleans that break up smoothly into touch-sensitive drive. An onboard FET boost circuit, high-gain Pigtronix FAT mode, and a genuine analog spring reverb give this small amp a surprisingly huge sound on stage or in the studio.
