Looks good. Works perfectly.

From the manufacturer:

A hand-wired, 100% analog, natural tube-emulating overdrive, clean boost, and tone enhancement tool with a proprietary, completely transparent tube-emulating variable and switchable JFET pre-gain clean boost control to push your BlackBox into high gear, or to squeeze more volume or fatness out of the front end.

Features three switchable circuit modes - Standard (Hi-Gain), Classic (Lo-Gain), and Clean Boost.

External Gain, Tone, Volume, Presence, and pre-gain Boost knobs, plus internal Bright/Smooth Voicing and Mode switches - highly interactive controls that tap your signal in just the right places for a HUGE spectrum of both clean and overdrive tones out of just one box. 

Extremely dynamic and vocal, with just a hair of compression and that amp-on-the-edge feel in Overdrive Modes - play softly or lower your guitar's volume, and your signal cleans up well; dig in and that hot tube growl will sing. Just a touch of mids to help cut through the mix without destroying your tone, and enough flexibility and transparency to enhance almost any setup, never detracting from the nuance and feel of the rest of your rig. 

Note: This model does not have the "Deep/Tight Voicing" switch - this is available only on the Stage Pro Mod version. 

EVERYTHING THE BLACKBOX OVERDRIVE CLASSIC IS, AND SO MUCH MORE

Like to keep it simple? The BlackBox Overdrive 2 can be switched to Classic Mode to convert the entire circuit into that of the simple 3-knob BlackBox Overdrive Classic, but with way more output volume. Everything but the Gain, Tone, and Volume controls can be deactivated. New for V2 - not available in 2016 models.

NEW FEATURES FOR V2 REDESIGN: 

• Completely redesigned from the ground up, with a unique internal switching system to use the pedal in True Clean Boost Mode with tons of headroom, or to bypass the preamp boost circuit for direct access to our low-gain Classic circuit, all with significantly higher output volume than the original BluesBreaker circuits

• Bright/Smooth Voicing switch
