Intro

The Portable Distortion 424 MKII Guitar Preamp With Bypassable Buffer captures the raw, grimy texture of a classic cassette 4-track preamp and puts it in a compact pedal. Its bypassable buffer dramatically shifts gain and character, allowing your guitar’s high-impedance signal to breathe. Expect everything from clean boosts with subtle EQ to treble lift, warm/dark textures, and explosive, chaotic grind.
