Eurorack hardware you didn’t know you needed

You know you need modules, a case, and power for your Eurorack system. This article isn’t about that. It’s about all the other stuff you don’t yet know will save your ass down the road.

Sure, you’ve been researching modules, watching videos, and talking in Discord or forums. But there’s a whole category of tools and hardware you don’t learn about until you’re installing a new module or troubleshooting a power issue and wishing you had them.

Here’s my list of essential items that will keep you focused on making sound and make modular life easier, safer, and far less frustrating.

Ribbon cables

Should you really be counting on your new module arriving with the right ribbon cable? Any one of these things could happen:

• No cable included
• Wrong length
• Wrong pin count
• Header pin stuck in connector
• Connector installed backwards (can damage modules)
• Broken cable

Power headers

Running out of power headers is more common than you think. Using smaller modules can fill up a busboard fast. If your power supply has enough juice but not enough headers, you’ve got some options:

• Add a “flying busboard” ribbon cable with multiple connectors spaced along it
• Add a small passive busboard and connect it to your main busboard with a 16-to-16 pin ribbon cable

Both options let you power more modules without adding a second case or supply.

Screws & friends

You can’t mount modules without them, and you’d be surprised how many cases ship without a full set. Don’t get screwed (forgive the pun) when a module shows up without mounting hardware. Instead of having it swing from its ribbon cable, keep extra screws on hand.

Screwdrivers

Even if you prefer knurlies, it’s smart to keep a decent screwdriver on hand for other screws and general tasks. A magnetic tip is essential, and a small powered screwdriver is a game changer.

Magnetizer

A simple magnetizer/demagnetizer block can turn any driver into a screw-holding champ. It’s saved me from fishing fallen screws out of my case more times than I care to admit.

External mults

Inline or passive mult modules work, but if your case is cramped, an external mult, like a small box or cable-style splitter, frees up HP and makes patching easier between cases.

Cable clips & Velcro ties

Managing cables can be an art form, but it doesn’t have to be hard.

Velcro ties – 100 for super cheap. Bundle patch cables or use around the studio.

Nylon paintbrush

A soft nylon paintbrush is one of the safest ways to dust your modules without scratching panels or blowing dust around. I like a 1 1/2” angled brush to get under knobs.

Hex and knurled nut drivers

If you swap out panels, you’ll need to remove and tighten nuts. There’s really only one option that won’t scratch panels.

Nylon electronic pry tool

Ever tried to remove a knob from a potentiometer and worried you’d scratch the panel? A nylon pry tool gives you leverage without damage. Essential if you do frequent module swaps.

Final thoughts

Starting Eurorack is exciting, but it’s easy to overlook these less glamorous items. Stocking up on them early means fewer frustrating interruptions and more time making music. Build a small Eurorack toolkit so you’re never hunting for the right screw or cable.
