Hand-Built Klon Style TL072 Op-Amp Guitar Buffer Pedal

This is a hand-built, low-noise audio buffer designed to preserve signal integrity in extended guitar signal chains. By providing a high input impedance and low output impedance, this unit effectively mitigates high-frequency roll-off (tone suck) caused by cable capacitance and true-bypass pedal arrays.

Technical Specifications

• Circuit Architecture: Utilizing a high-fidelity TL072 dual operational amplifier, a industry standard chosen for its low noise floor, excellent slew rate, and transparent frequency response.
• Impedance Matching: Features a high input impedance to properly load guitar pickups without loading down the signal, paired with a low output impedance to drive long cable runs to the amplifier without degradation.
• Enclosure & Layout: Housed in a compact, rugged aluminum enclosure with a brushed industrial finish, as shown in the image. Designed for maximum space efficiency on crowded pedalboards.
• Hardware: Features independent, chassis-mounted input/output jacks on the sides and a top-mounted DC power jack.
• Indicators: Equipped with a center-mounted LED status indicator.
• Aesthetics: Features a Zazu graphic affixed to the face of the enclosure, visible in the image. It's a sticker; if you don't like it, you can easily remove it.

Power Requirements

• Voltage: Standard 9V DC
• Polarity: Center-Negative
• Power Supply: Not included

Condition Note

This is a brand-new, hand-built unit. It has been fully bench-tested and verified for optimal electronic performance. As a handmade utility pedal, the brushed aluminum enclosure exhibits minor cosmetic surface variations characteristic of a custom build. Please refer to the image for an accurate representation of the physical unit.
