Hiwatt Pedalsmith 50W Pedal Platform Head, Effects Loop

Built for players who demand unmatched clean headroom and dynamic response, the Hiwatt Pedalsmith 50W Pedal Platform Head, Effects Loop (PEDALSMITH50H-U) brings the legendary Custom Shop DR504 circuit into the modern era.

Pushing over 50 watts of crystal-clear all-tube power through a pair of EL34 output valves, this British-engineered amplifier head is purpose-built as the ultimate pedal platform.

Inspired by the iconic 1970s Hiwatt amplifiers modified for Pink Floyd, the PEDALSMITH 50 features High and Low inputs that act as internally linked inputs—routing your guitar signal simultaneously to both the Normal and Brilliant channels.

Blend both voices to dial in everything from warm, punchy lows to articulate chime, and shape your core response further with a 3-way Filter switch offering extra treble or bass circuit variations.

To keep your time-based and modulation pedals sounding pristine even when pushing the four ECC83 preamp tubes, Hiwatt equipped the PEDALSMITH 50 with a clean, quiet post-preamp effects loop.

Housed in a tour-ready birch ply cabinet, it delivers classic British durability and unmistakable Hiwatt clarity on any stage or in any studio.
