From the discussion thread of the Youtube link from 90 dB:


"Why go to all that bother when you can buy a purpose built Shadows Echo Box such as a RFX 2000, or a Q2 box or even the new Shadexs box which cost under £40,00 (50$) and they are all pre programed in against the title of the tune"

However, not finding evidence of the existence of the 'Shadexs' box.

Pretty much any Zoom G series pedal will allow you to chain two different delays together.

Feedback is set just high enough on both delays to give a single 'repeat' of the original signal.

Shorter delay goes before the longer delay. At least that's the way I would do it, but the 'instructional video' shows a guy doing the longer delay first in the chain.

I'll see if I can set up a patch in my Zoom G5. Zoom G3 units have pretty much the same signal processing.

Here's a guy doing it with guitar and effects for under 200 pounds:

He's using a Zoom G1 ON which is a cut-down version of the G5/3. $50 at Sweetwater:
