Build a Legend: Guitar Amp Kits for Every Skill Level

There’s nothing like the sound of a hand-built tube amp—and nothing more satisfying than building it yourself. Our guitar amp kits give you the iconic tone of classic circuits, backed by modern reliability and detailed instructions that walk you through every step.

From gritty tweed overdrive to chimey reverb and soaring Plexi punch, our amp kits faithfully recreate the tones that shaped music history. These aren’t stripped-down shortcuts—they’re full-featured, high-quality builds made for serious players and passionate tinkerers.

Premium Components. Proven Circuits. Pure Tone.

Each of our guitar amplifier kits comes loaded with top-shelf parts: solid ¾” pine interiors, vintage-correct transformers, premium tubes, and period-authentic components throughout. The result? Killer tone, built to last.

Our instructions break down the build into bite-sized steps, complete with full-color photos, so even first-time builders can succeed with confidence. No guesswork. No frustration. Just hands-on learning and a pro-level result.

Amp Kits with Built-In Support

Every one of our amplifier kits is vintage-inspired and backed by our Lifetime Promise and a team of trained techs ready to help if you hit a snag. Whether you’re chasing classic tweed growl or want a rock-solid platform for future mods, we’ll help you nail the tone.
