Palmer PWT 12 MK 2 Mi

A format designed for modern and demanding pedalboards

As pedalboards have become enriched with digital pedals and high-consumption effects, the power supply has become a crucial link to maintain a clean signal and stable dynamics. The PWT 12 fits this logic: a universal power supply designed for intensive use, capable of delivering regulated power to multiple pedals simultaneously, while electrically isolating the outputs.

Who is the PWT 12 for, and in what uses does it make a difference?

The PWT 12 is aimed at guitarists, bassists, and effects pedal users who want a reliable foundation, whether in rehearsal, studio, or on stage. It is especially suitable for mixed configurations (analog + digital) where voltage stability and output isolation help reduce hum and interference. It is also a relevant solution if you use 9 V pedals that can accept higher voltage: switching to 12 V or 18 V (if the pedal allows) can provide more dynamics, clarity, and headroom before saturation.

Key Features: Stability, Isolation, and Creativity

12 isolated outputs for a quieter pedalboard

Each output of the PWT 12 is isolated, a crucial point to limit noise propagation between pedals. The result: a cleaner power supply, better suited for complex effect chains, and more consistency when stacking overdrives, modulations, and time-based effects.

4 variable 9 to 18 V outputs: more headroom or "sag" effect

Four outputs feature a voltage adjustment from 9 to 18 V. This flexibility allows two approaches: on one hand, powering compatible pedals at a higher voltage to increase dynamic range and rendering stability; on the other, simulating a voltage drop, like a sagging battery, to achieve a more "vintage" behavior on certain overdrives and fuzzes (softer attack, natural compression, different grain depending on the setting).

Built-in regulation and protections

The PWT 12 is regulated at constant voltage, which helps maintain consistent performance even when multiple pedals draw current simultaneously. It also includes protections against short circuits and overloads to secure the power supply and your equipment daily.

LED indicators: immediate control on stage

A power indicator confirms the unit is on, and a bi-color output status indicator allows quick visualization of the status. In live situations, this type of visual feedback saves time diagnosing a problematic cable, pedal, or output.
