Digital Delay // Build Along

How to build a PT2399 digital delay from scratch — echoes, slapback & ambient repeats, breadboarded step by step. 🔧 Join Mod Club → https://www.coppersoundpedals.com/sho... ━━━━━━━━━━━━━━━━━━━━ 🔧 WHAT WE'RE BUILDING Time to add some space. This month we breadboard a delay built around the beloved PT2399 chip — the heart of countless lo-fi and warm digital echoes. Dial in everything from tight slapback to long, trailing ambient repeats, flip between bright and dark repeat voicings, and blend it all to taste. It's our first real dive into an IC-based digital circuit, and it's a blast to build. 🧰 WHAT YOU'LL NEED Your Digital Delay Cir-Kit (in this month's Mod Club box) A CopperSound DIY Breadboard → https://www.coppersoundpedals.com/sho... A 9V power supply → https://www.coppersoundpedals.com/sho... 🎓 WHAT YOU'LL LEARN How a voltage regulator drops 9V to the clean 5V the PT2399 needs How the Delay knob changes the chip's internal clock to set repeat time Why the Repeats toggle swaps a capacitor to make echoes darker or brighter How the Mix control blends your dry signal with the wet echo 🔊 ABOUT THE CIRCUIT The PT2399 is a digital delay chip with a famously musical, slightly lo-fi character as the repeats decay. We regulate the power down to 5V, feed a clean pre-amped signal into the chip, and use a VCO control to set the delay time — more resistance for long echoes, less for tight slapback. A toggle in the feedback loop tips the repeats warm or bright, and a Mix knob blends it against your dry tone. A perfect first step into digital pedal building. 🎫 GOLDEN TICKET One random Mod Club box each month hides a Golden Ticket — find it, pick any Premium DIY prize up to $100. 💛 JOIN MOD CLUB A fresh, unreleased Cir-Kit at your door every month — experimental fuzzes, drives, delays & mods, bagged and matched, plus the build-along, bench tools, Jumbo Novelties & The Vault. → https://www.coppersoundpedals.com/sho... 🛒 SHOP COPPERSOUND → https://www.coppersoundpedals.com/shop 📲 Instagram @coppersoundpedals · coppersoundpedals.com Artistic Engineering.
