MAGNEZIUM is a two-channel preamp inspired by the sound of the highly-coveted “Magna” Super 59 amp. It combines Fender’s “tearing silk” and Marshall’s “clank” overdrive tones in one pedal, giving you the best of both worlds!

Key Features

  • All 12X7 Power – It’s equipped with a pair of 12X7 tubes operating at full 250VDC
  • True Bypass – With true bypass, you can be sure your signal will be clean when the pedal is not in use.

MAGNEZIUM features two fully independent channels – for low and high gain – and has an option of external switching between them via the 1/8″ side-mounted jack.

The low-gain channel delivers a rich bottom end with Bassman-style overdrive, while the high-gain channel adds a Marshall-style gain stage at the front of the circuit. Perfect for classic Southern rock sounds. Cranking the gain past noon will take you firmly into harmonically rich ZZ Top-riffing territory.

A toggle switch on the side of the preamp offers two output modes: a higher output for direct connection to a power amp or a cab sim and an attenuated mode with a treble cut for connection to the front of an amp.

The MAGNEZIUM has an all-tube signal path and true-bypass switching. – all converted from a standard 12VDC input.

Overdrive

Like a golden layer of melted cheese — warm, gooey, and just put it all over. It adds just the right amount of richness and grit, turning a clean signal into something smooth and savoury. Designed to mimic the natural breakup of a tube amp pushed to its sweet spot, overdrive delivers the flavour of classic rock and blues in every bite. From creamy mid-gain warmth to crisp edge-of-breakup sparkle, it’s the comfort food of guitar tone — simple, satisfying, and endlessly versatile. Whether it’s a mild crunch or a full-bodied roar, overdrive is where good taste begins.

Preamp

A preamp pedal shapes and boosts your guitar’s signal before it reaches your amp or recording interface, giving you control over tone, gain, and headroom. It acts as the first stage of amplification, adding warmth, clarity, and character while preparing your signal for the next part of the chain. Some preamps emulate the response of classic valve circuits, while others offer clean, transparent tone shaping ideal for acoustic instruments or direct recording setups.

Used on its own, a preamp pedal can serve as the foundation of your tone, providing a consistent core sound wherever you play. When combined with other effects, it enhances dynamics and helps each pedal sound more defined and natural. Whether you’re looking to push your amp harder, bring life to a dull signal, or refine your sound for the studio, a good preamp pedal adds presence, punch, and musicality to any rig.
