 This may be the equivalent of "Looping 101," but Boy! did I 
ever concoct some major swirl last night! The concept is simple: feed the 
delayed output of DD-20 #1 into the input of DD-20 #2, and vice 
versa. 
I use a Boss GT-3 to process my guitar, and the GT-3 has 
stereo outs, so I'll describe exactly how I set this up last night, but this 
should certainly work with a mono input as well.  
Here's the long skinny: Each DD-20 has two inputs and two 
outputs, k? I plugged one of each of the two outputs of the GT-3 into one 
of the two inputs on each of the DD-20s. Then I plugged one of the two outputs 
of DD-20 #1 into my usual mixer/amp/speakers. I plugged the other output 
into the second input of DD-20 #2. One of the outputs of #2 went to the 
mixer/amp/speakers, and the other output of #2 went to the second input of DD-20 
#1.  
With both DD-20s set to maximum feedback and slightly 
different delay lengths (about 18 and 19 seconds), there was no unsightly 
oscillating feedback! No harsh buildup of static or clock noise! Notes with 
undefined attacks expanded like watercolor pigments on a wet paper towel. 
Well-defined notes established a rhythmic pulse like nobody's business. And with 
two feedback controls, two effect levels, and two output tone controls, the 
in's and out's and color-tints and stereo spreads and what-nots became V-E-R-Y 
T-H-I-C-K. 
The use of the Behringer Ultralink that our new member Patrick 
just posted about would make switching between this setup and a more 
conventional setup rather easy. 
Now here's an output secret for all you DD-20 owners: you 
probably know that the DD-20 has four output modes (stereo +4 dB, effect/direct 
+4 dB, stereo -10dB, and effect/direct -10 dB). Well, when you execute the 
voodoo ritual that sets the output, it sets the output for only the memory that 
the DD-20 is on at that moment! Which means you can customize the output mode 
for each memory location. Boy, I'm loving these creamy little conjoined 
stomperoos more and more with every passing millisecond. 
Now I must go pester Mr. Kim about posting my DD-20 review on 
the LD web site.
