Quality you can feel
Pick up a finished GGG build and you can tell what went into it, starting with the board.
Roomy through-hole PCBs
Builders often praise our circuit boards. The layouts are spacious and forgiving, with room around every part, so they are far easier to solder than cramped, compact boards. (A big plus when you are still learning.)
US-sourced components
We buy from trusted US suppliers, never just the cheapest parts we can find. Every kit gets premium components, including germanium diodes where the circuit calls for them.
Hardware built to last
Top-quality audio jacks, pots, knobs and footswitches, all housed in a solid cast aluminum case made for years of stomping.
Detailed instructions
Our site contains clear schematics, wiring diagrams and instructions to guide you from start to finish.
