The 385 MKII Black is a seriously impressive overdrive, nailing that vintage tube amp vibe without the amp itself. The dual channels and 385+ boost offer a surprising amount of tonal flexibility, making it ideal for players seeking a warm, responsive drive for rock, blues, and even some heavier styles. It's a premium-priced pedal, but the sound and build quality largely justify the investment.

Frequently Asked Questions

The 385 MKII has a more dynamic response and a richer, fuller tone, lacking the mid-hump often associated with Tube Screamers. It's more of a complete amp emulation, rather than a simple mid-boost.
While it’s not standard, it's essential for the pedal's intended dynamic range. A dedicated power supply is recommended to avoid voltage drops and ensure optimal performance.
The 385+ switch engages an additional gain stage, adding significant sustain, harmonic richness, and a perceived increase in overall volume, making it suitable for lead tones or adding a thicker layer to your sound.
