Description

Black sleeving over a black jacket, black housings, black heatshrink. The only thing on the Black Mamba that isn’t black is the silver print on the shrink and the nickel at the tip. It’s built for the player who wants the cable to disappear — against a black pedalboard, a dark stage, or a photograph where the guitar should be the subject.

Underneath is the Sommer SC-Spirit LLX, at 15.8 pF/ft (52 pF/m) the lowest capacitance of any cable on the market. Capacitance is what rolls the top end off a signal as the run gets longer, which is why a 30-foot cable usually sounds duller than a 10-foot one. On the LLX that penalty is about as small as it gets, so this is the one to reach for when the run is long and you’d rather not hear that it is. A 21AWG oxygen-free copper conductor of 19 fine strands runs inside a braided OFC shield over a carbon screen.

MDPC sleeving sits outside the jacket, so it changes nothing electrically — it’s the layer that takes the wear instead of the cable. Terminated with G&H Bigfoot nickel connectors in black housings, hand-soldered with lead-free ROHS-compliant silver solder, built to order and tested before it ships. Backed by our lifetime warranty.

The same LLX runs under the Turquoise Tweed and the Purple Tweed if you’d rather it were noticed, or take it unsleeved in plain matte black.

The Black Mamba

I knew of, and used, Sommer LLX cables in my rig. Its capacitance is the lowest out there — 16pF per foot — which translates to improved high frequency response. While it's subtle in short runs, in longer runs the difference is more apparent. I was glad Duane stocks it; not everyone's willing to. I ordered one of Revelation's Black Mamba cables for one of the longer runs, and as expected, it subtly improved things.

Pure Sound

Road ready guitar cable. Clear highs, tight lows, punchy mids. Highly recommended.

Black Mamba Instrument Cable

I love my new Revelation instrument cables. The 18' Black Mamba cable with the extended length angle plug for the Tele sounds bright and clear. The 10' Black Mamba for my pedal steel guitar lets all the clean highs chime through. And the cables are extremely well built. Very high quality gear. Thanks, Duane.

Game changer!

Working with Duane to get the cables I wanted was a really great experience. The Black Mamba cables are incredible. I was seriously blown away by how much clarity and top end I got back. I wouldn't have believed it if I hadn't switched.
