Echo

Echo (released December 2007)(based on Marc’s EP-2 (tube))(Oldest units had Stomp Switch in middle of pedal, later units Stomp Switch is moved to the left)(How many made?)(Highest known number – )

Marc Says (via TGP):?
"There have been no major version differences ever since it came out. The Echo has had its share of small, incremental improvements over the years, mainly in terms of transparency, both of the dry and the delayed tone. An earlier Echo will have a bit more of a "dub" flavor, and a newer one will have a slightly "newer tape" quality."

"I've hard-wired two different compression circuits and multiple stages of low-pass filtering into mine in order to emulate the sound of a dark, old tape (and also to HIDE the noise that the chip makes when you under-clock it for higher delay times!). But the reason I use several stages of low-pass filtering is in order to shave off the high frequency noise, a little bit at a time, in several iterations, as opposed to just chopping off a lot all at once and infringing into the guitar's own frequencies and deadening the sound."

"Plus, my Echo actually adds a bit of distortion to the delayed signal, in a good way, I hope. It's subtle, but if you want a crystal clear delay tone, the Skreddy is not for you!"

Skreddy – “The standard Echo mix actually has a tiny amount of dry-signal boost when the mix is at 0%. This is to make up for any losses that come into play early on. So the standard mix where you’d typically set your echo-level knob at like noonish, you’ll find that on the Skreddy at more like 9:00 o’clock-ish, and no loss of dry signal. As the wet gets louder and the dry begins to attenuate, like noonish, the overall output level keeps up with unity all things being summed and mixed.

So yeah; as more folks seem to weigh in on never needing the 100% wet mix control (which I thought was a cool feature, like there are songs where this might be something you’d use, like a 60’s studio effect, a faux reverse-reverb, or obviously if you were using the Echo as an insert in a mixing console, etc.), I’m basically planning on the next version having the standard echo-level control instead of my current mix control. Also I’m almost certainly going to abandon the true-bypass switching and go to a buffered bypass with a trails switch. Nothing has been done on these fronts yet, though; so to head off your questions pre-emptively: no new version is in the works at least for the foreseeable future (6 mo+).

Some random bits I remembered about the Skreddy Echo (By Cookieshoes):

The earliest ones have the footswitch located in the bottom center of the pedal. Sometime in the first year or so, the footswitch moved over to the bottom left. Sometime after that, a thin line border was added around the main graphics on the face of the pedal.

From the time that the pedal was released in 2007 to early 2013, the standard finish was blue/green hammertone. Gold was also a standard option after the first few years. Sometime around 2013, the paint manufacturer discontinued the blue/green color, and all Skreddy Echos started being produced in gold.

As for mods, in 2012, a customer requested to add a toggle on the side of the pedal that would allow for changing the Wet/Dry functionality of the Mix knob. In the "stock" position, the Mix knob acts as it does on all Echos, and blends the Wet and Dry signals from 100% Dry at full counter clockwise to 100% Wet at full clockwise. Flick the toggle the other way, and the Mix knob keeps the Dry signal present all the way through the sweep, letting the user add the Wet signal in to taste. Other Echos have since been done with this mod, but with the toggle now located at the top of the pedal, beneath the 9v input instead of on the side.
Older and fairly rare
Super Rare early version with stomp switch in the center, not sure how many were made before the change or when.
