GMMK Pro
Everything you need to complete your GMMK Pro build
The GMMK Pro is a 75% gasket-mount keyboard with a polycarbonate plate, rotary encoder, and a premium aluminum frame. It's sold as a barebones kit — no switches, no keycaps — which means your build is entirely up to you. That's the appeal, and the challenge. Here's what you actually need to complete the build.
What ships in the box
The GMMK Pro barebones ships with the aluminum case, PCB, GOAT stabilizers pre-installed, and a south-facing LED board. No switches, no keycaps. The rotary encoder is included.
Switches are mandatory
The GMMK Pro is PCB hot-swap and accepts 5-pin MX-compatible switches. Since it ships without them, your first purchase needs to be a set of switches. The GMMK Pro's polycarbonate plate and gasket mount give it a bouncy, cushioned feel that pairs well with either light linears or medium tactiles. Heavy clicky switches tend to feel harsh in gasket mounts — the bounciness emphasizes the clack. Gateron Yellow or Oil King for linears, Boba U4T or Durock T1 for tactiles are popular choices.
Keycaps: layout considerations
The GMMK Pro is a 75% layout with a right-side column that includes Del, PgUp, PgDn, and End keys. Most TKL-compatible keycap sets will work, but check the specific modifier row. The rotary knob requires a separate knob cap — many third-party options fit it, including any 19mm D-shaft knob.
Lubing and filming
The GMMK Pro case offers excellent acoustics, but stock switches straight from a bag will be inconsistent and scratchy. Lubing with Krytox 205g0 (linears) or 3203 (tactiles) is the single best upgrade you can make. Adding switch films — thin plastic or foam layers that sit between the top and bottom housing — reduces wobble and improves sound consistency, and is worth doing while you have everything on the desk.
The rotary encoder
The included rotary encoder works with GLORIOUS CORE software or QMK/VIA for custom keybindings. Out of the box it controls volume. Via the software, you can map it to scroll, zoom, media control, or any custom function. It's one of the GMMK Pro's best features and underused by most owners.
Frequently asked questions
Does the GMMK Pro come with switches or keycaps?
No. The standard GMMK Pro barebones kit includes the case, PCB, and GOAT stabilizers only. You need to purchase switches and keycaps separately. Glorious sells their own switches and keycaps, or you can source from third parties.
What plate material does the GMMK Pro use?
The standard GMMK Pro uses a polycarbonate (PC) plate, which is flexible and contributes to the soft, bouncy typing feel. Glorious also sells brass and aluminum plate options separately if you prefer a stiffer, firmer feel.
Is the GMMK Pro compatible with QMK?
Yes. The GMMK Pro is fully QMK and VIA compatible. You can remap all keys, create layers, configure the rotary encoder, and control RGB via the open-source QMK firmware or using GLORIOUS CORE software.
What size stabilizers does the GMMK Pro use?
PCB-mount screw-in stabilizers. The GMMK Pro ships with GOAT stabilizers pre-installed, which are decent. If you want to upgrade them, Durock V2 or TX stabilizers are common replacements. You'll need 2u stabs for the shift keys and backspace, and a 6.25u for the spacebar.
What is the best sound mod for the GMMK Pro?
The most effective single mod is adding a layer of PE foam (thin craft foam or packing foam) between the PCB and the plate. This reduces the high-pitched ping common in aluminum-bodied keyboards and produces a fuller, lower-pitched sound. It costs under $5 in materials. Combined with lubed switches and lubed stabilizers, this transforms the GMMK Pro's acoustics completely.
Can I use the GMMK Pro without the Glorious CORE software?
Yes. The GMMK Pro is QMK and VIA compatible, so you can configure every key, layer, and macro entirely through the open-source VIA web app without installing Glorious CORE. GLORIOUS CORE is optional and primarily useful for simpler RGB customization and rotary encoder setup if you prefer a GUI over QMK config files.
What switches work best in a gasket mount keyboard?
Gasket mount designs like the GMMK Pro suit light to medium linears and medium tactiles best. Light linears (Gateron Yellow, Gateron Oil King, Akko Jelly Pink) sound smooth and bouncy. Medium tactiles (Durock T1, Boba U4T) feel deliberate without feeling harsh. Heavy clicky switches tend to feel jarring in gasket mounts because the flex amplifies the click impact. Avoid extremely heavy springs in gasket builds for the same reason.
Pro tip
The GMMK Pro ships with a south-facing RGB LED board, which can cause 'shine-through' issues with north-facing keycap legends. If you're picky about RGB alignment, look for south-facing-compatible keycap sets, or just accept that the shine will be on the front face of the keycap instead of top — it actually looks good that way on most sets.
