Superior Eight Amplifier Kit

Modulus Super Eight Amp Kit Suggested Layout: DOWNLOAD

The Superior Eight kit delivers the timeless clarity and sparkle of a classic Blackface-style preamp, long considered the industry benchmark for clean tones. Pairing this iconic circuit with a single-ended 6L6 power stage, the amp offers rich, bell-like response, dynamic feel, and the perfect amount of usable volume for home, studio, or small rehearsal spaces.

Thanks to the front-panel power selector, you can enjoy authentic valve tone without rattling the neighbours—or attracting a visit from the police.

Ideal for hobbyists, tone chasers, and DIY amp builders, this kit captures the soul of a vintage clean amp in a compact, responsive 8-watt package.
