The 424 Gain Stage gives all the elastic, lo-fi tone inspired by a guitar being plugged straight into a vintage 424 multi-track recorder.  With the 424 Gain Stage pedal, you can easily integrate the rubbery clean tones, high head room, and smashed out fuzz that’s being repopularized by today’s emerging guitarists.  

Multi-track recorders were made famous in the ‘80s and ‘90s, and gave musicians and songwriters the ability to bring our songs to life from the comfort of our cluttered bedrooms. These devices meant for home studios eventually found their way onto hit records like Springsteen’s Nebraska, the Wu-Tang Clan’s Enter the Wu-Tang, and Spoon’s Gimme Fiction. Many of the vocal parts and fuzzy guitar tracks on Gimme Fiction – a huge inspiration for the creation of the Colour Box – were actually recorded on a vintage multi-track unit. Since hearing those recordings, the 424 Gain Stage has been brewing in the background, and now we’re proud to bring it to you.

In this historically accurate recreation, we perfectly replicated the original 424 MKI circuit using the original UPC4570 and NJM4565 op-amps and all the original controls, which is crucial for recreating the unique character that makes the old units sound so good.  The 424 MKI’s gain controls–trim, channel volume, & master volume–all work in tandem for dialing up your desired tone and can be further refined with the Low and High EQ settings. In addition, our unit offers a ¼” output alongside a balanced XLR output (DI out) for ultimate flexibility in any situation, live or studio.

The 424 Gain Stage as a DI

Going DI will give you the exact same unparalleled gooey texture and lo-fi fuzz you get when plugging directly into a 424 without the hassle of dragging around your beloved multi-track recorder. Leave it on your recording desk for easy access. If you want to get fancy,  you can toss an Active A/B/Y switcher at the end of your rig and send the A output to your amp and the B output to the JHS 424 Gain Stage input, then XLR output of the pedal directly into your mixer or interface. This way, you can flip between your amp and the 424 Gain Stage easily or play through both at the same time. Give it a try! 

The 424 Gain Stage with an Amp

Plugging a multi-track recorder into your amp is quite a feat. In this pedal format, you can easily integrate the tone of the 424 with the saturation of your favorite amp. This adds a whole new quality to the tone and gives the ability to stack it with your other pedals. Use it as a gain stage to boost your signal, a unique and colorful new overdrive sound, or push the gain knobs into full-on overloaded and broken fuzz.
