Why & How to Build a Piezo Preamp for your Cigar Box Guitar / Preamp for Contact Mic

You'll need a piezo preamp to get the most out of your cigar box guitar with a piezo pickup (aka contact mic). Piezo preamps resolve the frequency and dynamics issues caused by your piezo's high impedance output. You can purchase a piezo preamp, aka acoustic guitar preamp/DI, online on Amazon and any audio equipment supplier. However, its more fun and cost-effective to go DIY, especially if you're building multiple preamps for your cigar box guitar business. In this tutorial, I will reveal why you need a piezo preamp in more detail, and will take you through the process of how I built my piezo preamp using a popular circuit schematic featured in Collin's Lab and homemade-circuits.com. Below, I provide links to resources, including Amazon Affiliate links, to help you kickstart your build. Cheers! -Dr. Liza Seigido
