So what is a " barber pole through-zero flanger?"
Well, essentially, the Shepard's End is a flanger, but its unlike any flanger you've ever heard, played or experienced.  While the term "Barber Pole" sounds neat-o-speed-o, what it really means is that this flanger does not have a beginning, or an end to its cycle.  WHAT?!

You know how most flangers go up, then back down?  Well, this one doesn't do that.  Nope.  It goes up, continually.  It goes down, continually.  It can even go through the zero-point (that amazing over the top wooshing sound you hear on so many records), continually.  This just depends on how you set the controls.  And they're pretty easy to use.

Shepard's End Sub Zero

FwonkBeta has that fonk that'll have you telling everyone in the room you swear you changed your socks this morning.

But its that Purple. Purple funk.
Get up for the DownStroke.

This Envelope/Low-Pass filter is funkier than nine pounds of shaving powder, and with the Fwonk control up high, it is anything but subtle or mellow.

Serious low-end thump when desired, the FwonkBeta will probably knock down anything hanging on the wall, and maybe even push around free standing furniture. It is just that off the chain.

FwonkBeta

The diamond ocean.

Pure, gentle light fluidly undulates and glistens as the complex aural syrup flows and morphs into a stunning harmonic nectar.

Four discrete modulated delay lines interweave and braid together creating a multi-dimensional chorus unlike anything else available.

Smooth, natural and deep.  This is the DoubleChorus.

DoubleChorus

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.
