Mostard

The Mostard by RhPf Electronics is no bland boost. With up to +30 dB of ultra-clean gain, it brings clarity, energy, and a unique sparkle to your tone—like switching the light on your guitar sound. Whether you need to wake up a dark amp, cut through the mix, or add bite and presence, Mostard is built to spice up your playing.

The Mostard by RhPf Electronics is designed to do more than just make you louder, it makes your tone come alive. Delivering up to +30 dB of ultra-clean gain, it adds brilliance, punch, and a crisp attack that instantly lifts your sound. At low settings, it stays smooth and fluid; as you push the gain, it becomes sharp, articulate, and perfect for solos or pushing your amp into breakup.

Its EQ section isn’t a simple bass–mid–treble boost. Instead of piling on frequencies, it sculpts and refines your tone, helping you sit perfectly in the mix.

Expressive and Precise Controls

Gain – Clean boost that gradually adds treble as you turn it up.
Low – Tightens the bottom end without ever getting muddy.
Mid – Smooths out boxiness or adds clarity and presence.
High – Tames harshness or brings out sparkle with finesse.

More Than Just a Boost

Mostard is not just a utility pedal, it’s a tone activator. Always clear, never harsh, it can stay on all the time to enrich your core sound or kick in at key moments to shine through the mix. Like a good hot sauce, a dash adds flavor, but crank it, and be ready to burn.
