Obsessive Audio Wolfbox DI / Triad A11J

Vintage Mojo for Your Tracks

The Wolfbox DI is a boutique, hand-wired passive direct box built around the ultimate holy grail of audio iron: the original-spec Triad A-11J transformer.

If you want your bass, synths, or guitars to sit perfectly in the mix with real analog depth, three-dimensionality, and natural harmonic warmth—this is the box you’ve been looking for.

Key Features

Triad A-11J Transformer: The exact legendary iron responsible for the punch and smooth midrange of the historic Motown hits.

Variable Attenuation Control: A classic top-panel rotary dial lets you perfectly back off hot signals from active basses or modern synths.

100% Passive Mojo: No batteries, no phantom power, zero noise. Just pure, unadulterated transformer saturation.

point-to-point wiring housed in a wedge shaped,  hammer gold & black enclosure.

Pushing low-frequency transients into the Triad core generates musical 3rd-order harmonics. This delivers natural compression and presence without touching an EQ.
