Hiwatt PEDALSMITH 50 - 50W Pedal Platform Amplifier Head

Hiwatt Pedalsmith 50 – The Ultimate Pedal Platform, Reborn

The Hiwatt Pedalsmith 50 is the definitive evolution of the legendary DR504 circuit, rebuilt with modern engineering and player-focused innovation. Delivering over 50 watts of crystal-clear, dynamic headroom from a pair of EL34 output valves, it provides the unmistakable Hiwatt tone that shaped decades of iconic recordings—tight lows, piano-like clarity, and massive punch.

Designed for players who build their sound with pedals, the Pedalsmith 50 features High and Low inputs, each functioning as a linked input inspired by modified 1970s Hiwatt amps famously used by Pink Floyd. This sends your signal to both the Normal and Brilliant channels simultaneously, allowing deep tonal sculpting and unmatched responsiveness to your guitar and effects.

Taking Hiwatt’s reputation as the ultimate pedal platform even further, the Pedalsmith 50 adds a clean, quiet post-preamp FX loop, ensuring delays, reverbs, and modulation pedals remain pristine and full-bodied after natural valve gain. A three-position Filter switch expands the circuit’s tonal range, offering enhanced treble or bass response while preserving the amp’s classic British character.
