🎁 Bonus PCB Program – Exclusive, Limited, and Free with Your Order

To give something extra back to the builders who support GuitarPCB, I’ve launched a Bonus PCB Program — a rotating series of high-quality, limited-edition circuit boards you won’t find in the regular catalog, and that are never available for sale.

How it works:

• Free with any $15+ merchandise purchase (excluding shipping)
• Automatically included in qualifying orders — no codes, no forms, no extra steps
• Rotates regularly with new, unique designs each round
• Limited-run & collectible — once a round ends, that bonus is gone!

Round 18 – Now Active!

📅 Started: 11/06/25

Round 18 Bonus Includes:
Unlike previous rounds featuring two smaller boards, Round 18 offers a single, more robust design — the kind of build any serious overdrive fan will want to add to their collection.

1. ThorpyFX Gunshot – Designed to be the overdrive to beat all others, this circuit uses a proprietary cascading gain engine tuned for maximum tonal range. It delivers everything from subtle grit to searing hard-rock drive, responding like a valve amp with rich harmonic complexity and superb touch sensitivity.

Previous Round – Round 17

📅 Started: 10/17/25
🛒 Ended: 10/19/25

Round 17 Bonus Includes:

1. Krank Distortus Maximus – Inspired by Krank amplifier circuits, this high-gain distortion PCB delivers aggressive, saturated tones with tight lows, bold mids, and crisp highs. The active EQ lets you precisely shape your sound, with gain stages from punchy crunch to full-on saturated lead.
2. Danelectro Nichols 1966 – A resurrected design based on Steve Ridinger’s first pedal circuit built in 1966. It sits between fuzz and distortion, delivering thick, sustaining overdrive. Players note you can coax everything from a warm overdrive to biting fuzz, and it interacts well with different guitars and amps thanks to its dynamic response.

Previous Round – Round 16

📅 Started: 10/10/25
🛒 Ended: [10/13/25]

Round 16 Bonus Includes:

1. Alexander Jubilee Silver Overdrive – Based on the legendary Marshall 2555 Silver Jubilee, favored by Slash, John Frusciante, and Joe Bonamassa. Offers articulate low-gain crunch to rich British overdrive with dynamic response and harmonic depth — without the volume.
2. Maxon808X Extreme – Modified OD808 circuit with extended frequency response for clarity and definition. Boosted high-end cuts through the mix without harshness. Harder clipping gives aggressive, amp-like distortion. Drive backed and Level full works great for chugging tones.

Carefully tuned gain and clipping stages provide smooth, amp-like breakup with excellent note definition and dynamic sensitivity.
2. Lovepedal Purple Plexi – An LM386-based overdrive that captures the classic punch and harmonics of vintage Marshall amps. Volume, Tone, and Drive controls let you dial in everything from mild crunch to full-on rock saturation with dynamic response and rich midrange character.
