Description

Edit description

Unleash the legendary tones of the blues with the StewMac EC Expander Pedal Kit. Designed to bring out the best in your pickups and pedals, this DIY kit is inspired by the iconic Strat MDX control used by Eric Clapton. With a simple turn of the knob, transform your single coils into rich, vintage humbucker tones, adding a new dimension to your sound without the need to modify your guitar.

Whether you're looking to inject a subtle mid-range warmth or completely revolutionize your amp's tone, the EC Expander offers versatility with just two intuitive knobs. Stack it with your favorite overdrive or distortion pedal to break through the mix and rediscover your sound. This pedal isn't just about boosting—it's about unleashing creativity and giving you control over your sonic landscape.

Building your own pedal has never been more rewarding. The kit includes all the components you need, from top-quality resistors to a rugged metal enclosure with pre-drilled holes. The 3PDT breakout board ensures low noise, while rear-mounted jacks offer seamless cable management. Plus, with true bypass functionality, your signal remains pristine when the pedal is disengaged.

Dive into the comprehensive, step-by-step instructions with full-color illustrations, and take pride in creating a pedal that reflects your personal style and sound. Choose between painting your own enclosure or opting for a pre-coated finish, making it uniquely yours.

Key Features:

Powerful mid-boost circuit inspired by Eric Clapton's Strat MDX control
Two control knobs for versatile tone shaping
True bypass for clear signal integrity
3PDT breakout board for low noise performance
Rugged metal enclosure with pre-drilled holes
Rear-mounted input, output, and power jacks
Custom printed labels for a professional appearance
Powered by a 9V power supply (sold separately)
