The JHS 424 Gain Stage captures the raw, elastic magic of plugging straight into a vintage 424 multi-track recorder — now in a compact pedal that won't hog your pedalboard real estate. This is your ticket to those gloriously gritty, lo-fi bedroom recordings that shaped indie rock history, from Springsteen's haunting Nebraska to Wu-Tang's grimy Enter the Wu-Tang.
What Sets the 424 Apart
The 424 Gain Stage delivers exactly that elastic, lo-fi goodness that made bedroom producers into chart-toppers, but without the hassle of lugging around vintage gear that's older than half your bandmates.
Historically Accurate Circuit Recreation: JHS didn't just phone this one in — they meticulously replicated the original 424 MKI circuit using the exact same UPC4570 and NJM4565 op-amps that made the originals sing.
Triple-Threat Gain Control System: The three gain controls (Trim, Channel Volume, and Master Volume) work in perfect tandem, just like the original.
Dual Output Flexibility: With both 1/4" and balanced XLR outputs, you're covered whether you're hitting the stage or hitting the studio.
Playability That Adapts to Your Creative Vision
Whether you're a bedroom producer crafting lo-fi masterpieces or a stage warrior looking to add vintage grit to your arsenal, the 424 Gain Stage bends to your creative will like putty in your hands.
Effortless Integration with Your Setup: Seamlessly stack it with your existing pedals to create rich, layered textures, use it as a clean boost to push your amp into smooth, saturated tones, or crank the gain for wild, broken fuzz chaos. It works harmoniously with other gear while maintaining its own unique character.
Versatile EQ Control: Shape your tone effortlessly with intuitive Bass and Treble knobs. From warm and woolly to sharp and biting, simply dial in the sound that feels right — no guesswork required.
Direct Recording Made Simple: Recording direct? The balanced XLR output ensures all the lush, gooey textures without the hassle of vintage gear upkeep. Ideal for producers seeking authentic 424 multi-track recorder vibes without the maintenance headaches.
Design That Honors the Original
This isn't some cheap knockoff — it's a loving tribute to the gear that soundtracked a generation's musical awakening, built with the quality and attention to detail that JHS is known for.
Premium Components Throughout: From the original-spec op-amps to the carefully selected capacitors, every component was chosen to recreate the authentic 424 experience. It's vintage tone with modern reliability.
Compact Pedalboard-Friendly Format: All that vintage 424 magic squeezed into a standard pedal enclosure that won't dominate your pedalboard like some tone-hungry monster. Sometimes the best things really do come in small packages.
Studio and Stage Ready: No matter if you're tracking in your home studio or performing live, the 424 Gain Stage adapts to any environment.
Your Gateway to Lo-Fi Legend Status
The JHS 424 Gain Stage isn't just another pedal — it's your direct connection to the sounds that launched a thousand indie albums and inspired countless bedroom producers to chase their musical dreams. Whether you're after those signature rubbery cleans or that beautifully broken fuzz, this little box of vintage magic has got your back.
