From the vendor

NostalgiTone ModBender

Description

ModBender takes the legendary three-transistor fuzz architecture that defined some of rock’s most iconic tones and refines it for today’s builders. Using three 2N3903 silicon transistors selected for their lower gain characteristics, ModBender delivers the aggressive harmonic character, sustain, and dynamic response associated with classic Tone Bender circuits while providing improved consistency and reliability.

Unlike traditional tone controls that shape a broad range of frequencies, ModBender features a dedicated high-frequency contour control that allows players to fine-tune the upper harmonic response of the fuzz, allowing players to adjust the balance between cutting definition and a more subdued vintage character.

🔌 Easy Wiring: No more daunting wiring hassles! Say hello to beauty under the hood. Enjoy all-analog tones with modern features that will slip into your gig bag, ensuring you are always ready to unleash your musical magic.

🛠️ Available Components: We recognize the hurdles of component availability. Rest assured, we’ve carefully selected components for the NostalgiTone series currently available from today’s popular vendors.

Mainboard Dimensions – 2.10” x 2.12”

Included with each PCB purchase. – (1) Mainboard, (1) wiring board, and (1) ribbon cable.
