PROJECT NAME
BUSINESS CARD DRIVE
BASED ON
Lovepedal Eternity
EFFECT TYPE
Overdrive
PROJECT SUMMARY
A low-parts-count overdrive based on a stripped-down Tube Screamer, this circuit is the template for
many high-dollar boutique drive pedals.
OVERVIEW
The Business Card Drive is a fully-functional overdrive effect disguised as a business card. It's designed
to fit the same enclosure style as the new 125B projects, although since it doesn't come with a bypass
PCB, the bypass footswitch and LED must be wired manually.
A full-sized project based on the Lovepedal Eternity will be released soon.
USAGE
• Tone controls the treble response of the effect. The center point (12:00) is flat. When turned to the
left, it cuts treble, and when turned to the right, it boosts treble.
• Drive controls the amount of gain in the op-amp feedback diode clipping stage.
• Volume controls the overall output of the effect.
