RedSeven Numero Uno - KT88 Valve Guitar Amp Head

Numero 1 is the result of a collaboration that began in 2024 between RedSeven Amplification and Australian guitarist Stefan Hauk, born on the road during Stefan’s first European tour, when a backline search turned into a new amp idea within minutes. The goal was simple, deliver what we believe to be the ultimate blues tone through the pure signal path of a single channel design. Instead of the traditional approach of pushing lower powered tubes, Numero 1 takes the opposite route, four KT88 tubes, up to 100 watts, and massive headroom that keeps your lows firm, your chords open, and your dynamics intact at real stage volume. The preamp is carefully voiced to move seamlessly from a rich, dynamic clean tone to a full, fat, screaming overdrive, and the amp features our fully transparent FX loop, designed to stay out of your tone, with automatic bypass when unused. Feel and control Numero 1 is made for players who ride dynamics, pick attack, and guitar volume. The circuit stays responsive, and the KT88 power section keeps the foundation solid, so you can play with confidence in the mix, on stage, and in the studio. Dual footswitch, more range, same identity Gain 2 gives you a secondary gain level you can preset, so you can jump between clean and drive without changing the amp’s identity. The tube boost adds extra punch when you need to step forward. FX loop that stays invisible The Send and Return loop is designed to be fully transparent, and it automatically bypasses when nothing is connected, keeping the signal path clean and direct.
