PREAMP / DISTORTION / OVERDRIVE

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 vintage unit. 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 vintage 424 unit 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.

She loves it!
Size: 4 Pieces, Size: 4 Pieces
Tried it as soon as we received it. My dog is a doberman german shepherd mix. I used multiple levels to see what my dog can figure out. It kept her pretty occupied for about 15 minutes and then I readjusted the last level so she could figure it out. With that being said, it can definitely keep them busy for longer! This is going to be a great toy, we love it already. Very durable for my girl, she's a pretty heavy chewer. Very easy to clean because it's a rubber material. The overall puzzle design is also great, really gets them to think. Very easy to stuff treats or kibble inside. Lastly, I LOVE that it's blue and yellow! I wish more toys were in blue and yellow because dogs are color blind! I would definitely consider getting more pieces in the future.

Durable and fun
Size: 4 Pieces, Size: 4 Pieces
I have a chewer who gets bored in the afternoon. She loves these Lego blocks. They’re sturdy enough for a big chewer and they hold her interest . She really enjoys figuring out how to get her breakfast!

Love the idea!
Size: 6 Pieces, Size: 6 Pieces
Love the idea of this product! Arrived 3/25/2026 and started using it the same day. Lab puppies (8 months old) loved it too, until one of the tabs was chewed off 😞 One of the puppies ate something (not this product) last week and was sick & finally threw up the rubber pieces he ate. So they can’t use the toys they love!

Get 8 pack for bigger / stronger dogs
Size: 6 Pieces, Size: 6 Pieces
This is the best puzzle toy i have found for my GSD mix. All around high quality product 10/10. Thick, durable rubbery material that holds up against a strong chewer. Individual pieces are big and bulky enough that i don’t have to worry about my bigger dog accidentally (or intentionally) swallowing a piece, so i don’t need to supervise. That being said, if you have a bigger dog or a strong chewer, i HIGHLY recommend getting the 8 pack if you actually want to keep them busy for more than 20 mins consistently. Bigger dogs just have more leverage to tug on the pieces because obviously…they are bigger, so its just easier for them. The more pieces you add and more tangled/thicker you can make it, the less leverage they have and the harder it is for them to get a good grip. I have a german shepherd/pitbull mix (big boi, v smart, v strong) and i initially got the 4 pack which, after the first few times, only took him about 5 mins to get all the pieces apart even with level 5 connections. So I ordered an additional 6 pieces (i have a total of 10 pieces now) so i could make it harder for him and it was totally worth it. Now I use 8 pieces with level 5 connections and vital essentials freeze dried beef liver treats inside for my GSD and it consistently takes him 30+ mins to get the whole thing apart. I have timed this lol. I can rebuild the 8 pieces multiple different ways to make it more or less challenging (but i always opt for as difficult as possible to keep him entertained for as long as possible) I use the other two pieces with a level 1 or 2 connection for my other dog- bordercollie mix who is not a very strong chewer, he mostly just rolls it around/ licks it until it finally opens or i help him. Both of my dogs are obsessed with this. And i love watching them try to figure it out.
