Preamp
Preamp-style overdrive for amp-front enhancement. Delivers smooth breakup with responsive touch dynamics.
The PreDrive functions as a preamp stage before your amplifier. The circuit adds gain and shaping like an additional preamp tube. The design integrates with your amp rather than replacing its character.
Controls adjust the preamp gain and tone. The effect feels like an extension of your amp front end. The preamp approach differs from typical overdrive pedals.
Pettyjohn built the PreDrive for amp enhancement. The preamp character works with rather than against your amplifier.
