Setup, Repair & Upgrades
Learning how to build a guitar doesn't stop at assembly — this hub is your practical guitar setup and repair library: action height, truss rod adjustment, intonation, pickup height, bridge installation, wiring, shielding and playability upgrades. Use these step-by-step guides to turn a basic build into a stable, performance-ready instrument. If you're starting from scratch, our diy guitar kits give you a platform to apply every step here.

If you only read three posts, start with these. They cover the highest-impact adjustments for real playability.
Relief and action are the foundation. Get this right before chasing buzz or intonation.
Correct geometry is everything. Measure first, drill later.
One of the fastest tone upgrades once the guitar is stable and intonated.
Before you drill (fit & alignment)
When building a guitar, these checks prevent most "irreversible" mistakes: neck fit, scale alignment, bridge geometry and clean assembly.
Core setup (relief, action, intonation)
This is the "order of operations" that makes troubleshooting easier and results more repeatable.
Bridge installation & trem systems
Choose the guide that matches your hardware. Bridge geometry + setup method depend on the system you install — and if you need to learn how to tune a Floyd Rose, start with the dedicated guide below.
Electronics & noise control
Wiring and shielding are high-leverage upgrades when done cleanly (and tested before final assembly). Browse compatible guitar parts to source what your build needs.
Playability upgrades
When you want "pro feel": nut refinement, fret leveling, and dialing in the final touchpoints.
Bass-specific setup
Bass geometry and tension make setup feel different. Use these as a starting point.

Quick FAQ
Fast answers before you start adjusting or upgrading.
In what order should I do a guitar setup?
Relief (truss rod) → action (bridge/saddles) → nut height → intonation → pickup height. Changing one step can affect the next.
What causes buzzing after assembly?
Common causes are incorrect neck relief, action too low, nut slots too deep, uneven frets, or bridge geometry issues. Follow the setup sequence to isolate the cause.
Do I need shielding tape?
Shielding can reduce hum and interference in many builds, especially with single coils or noisy environments. Correct grounding and clean wiring matter just as much.
Bridge positioning: what's the biggest mistake?
Drilling before confirming scale length and intonation travel. Always measure and dry-fit before committing to holes.
Should I do setup before or after finishing?
Do alignment checks and dry-fit before finishing, then do final setup after the finish has cured enough to resist imprinting.
