Echobase - adding a second output

The Echobase is working really well for me, it's a great delay. Since I have two amps now I was thinking if there's an easy way to add another output to the pedal so I could simply connect the pedalboard directly to the two amps. Is there a simple solution to this? Cheers!

Run a wire from output jack 1 tip to output jack 2 tip and ground output jack 2. That would be the easiest way. ;)

I think you want dry going to one amp and the delay going to the other, yes? Much more interesting than duplicating your dry/delay mix and having the same exact sound from the two amps. This is actually very simple. See the 10k coming from the input stage to the output?  If you remove that 10k from the output, the output will be delay only.  (I think the clean switch mod on the off isn't quite what you want.). Remove that 10k from the output stage and put it to a 1/4 jack of its own.  This is your output to the dry amp.
Ok, here's something you should do in case you want to use this in a mono, one amp setup. This 2nd output jack you've added- you can use a toggle switch which will
-disconnect the the 10k from the output at the output side of the 10k (removing the dry from output 1),and
-connect this 10k thru a new .22uf cap to the tip of the 2nd, dry output jack.  Give this new jack a 100k resistor to ground, just like output 1.
With the toggle one way, your current output jack will act like it does now, the other way it will do the two actions above.

There is also a fancy pants way of using a switching jack so the insertion of a cable into the 2nd output jack will do this for you.  I don't think you should go that way, but check it out.
If one of your two amps is somewhat "primary" to you, you'll want that to be the dry amp on output 2 in a stereo setup, but you would want it to be delay-capable if you don't want stereo, in which case it would be on output 1.
The 100k level control will need to be maxed when you are in stereo mode.  If delayed output 1 doesn't match the dry signal on output 2, which you will want, change the feedback resistor in the output stage from 10k to 20k and use the level control to balance.  I would make this resistor change a function of the toggle switch above. If you don't, you will have an overall gain change in mono more that you might not want.
Will someone confirm this for him please?
