As the name suggests, the Ambience pedal creates a delicate wash behind your playing, softening the mood with the syncopation of multi-tap delay and the
gentle embrace of ambient reverb.
While it can be used just like a normal delay pedal, there’s some really neat stuff happening under the hood that gives it the vibe, feel and tone it delivers.
Start with a delay pedal, add a second,
syncopated echo tap and then modulate them both. Independently. Let those echoes drift into a soft reverb… 
now we’re getting somewhere

Ambience Echoverb

The Mr. Black Solid State Echo Chamber (SS-850) is a digital delay pedal that emulates the sound of vintage tape echo units. It features a unique design with a slider-based time control, reminiscent of the old EchoPlex or Fulltone Tape Delay. The slider allows for precise delay time adjustments, and an LED on the slider flashes the tempo as you move it or when using the tap tempo function.

SS-850 (Solid-state Echo Chamber)

That elusive, haunting, tubular sound known as Through-Zero Flanging, once only possible with a pair of outboard reel-to-reel decks and just the right touch, has finally been captured, slathered in butter and shoe-horned into one bad-ass little pedal known as the TunnelWorm TZF.

TunnelWorm can do a whole lot more than just through-zero flanging. A quick turn of the Zero knob and you can easily dial in a classic flanger, airy chorus and even watery rotary tones. For such a tiny pedal, it sure does dole it out. Check out the sound clips below!

Tunnel Worm

While the JDS-50’s sleek and un-assuming looks may insinuate that you’ve got a standard overdrive pedal before you, the JDS-50 really isn’t quite like any other overdrive out there.

From its perfectly balanced frequency spread, to the ridiculous dynamic response held within, the JDS-50 is not only an indispensable pedal-board staple, but a highly expressive instrument unto itself.

Effortlessly delivering tones ranging from meticulously tuned, touch-responsive crunch, to thick harmonic-laden overdrive and even to near-full distortion, the JDS-50 not only sounds phenomenal, but responds and feels like a high-quality tube amplifier, all while retaining the unique signature tonal characteristics of your guitar, or bass.

JDS-50 Overdrive

The Super-Extra Five Thousand features two independent, true-bypass channels:
The Amplifier Driver and The Super Booster.

The Amplifier Driver channel is a perfectly voiced drive-channel with a clean amp, or a damned fine way to push a dirty amp into all out high-gain mayhem.
The Amplifier Driver is nearly impossibly dynamic and can get totally clean, just by softening your pick attack or rolling back your guitar volume control, and it is not impedance sensitive so its incredible dynamics are retained with passive and active pickups alike.
It's got that elusive, super-sweet top-end with incredible articulation, detail and response, and can be fed directly into the Super Booster which generates +1dB to +14dB of pure, clean volume-- perfect for popping out for a lead or REALLY banging your amp.

You can also simply use the Super Booster on its own as a VERY powerful clean booster or effects chain buffer/driver.

The Super-Extra Five Thousand's ideally matched impedances allow it to seamlessly integrate anywhere in your effects chain.
