Thank you for sharing further. That diagram is an accurate possible set up, that should allow for successful use of reverb, and delay(although I prefer the reverb to be post delay, personally). I have personally set mine up in a similar fashion before(minus the dirt box), and had it perform as expected...perfectly. I had no “inactivated” delay issue...at all. My delay pedal is not the same model as yours, but it is made by the same manufacturer.(mine is the Boss DD-20)The '4 cable' just didn't offer me anything, and I hooked it up several different ways:

In fact, when placed last before the amp, the NS-2 had dramatic noise reduction capabilities that it did not have when hooked up in the 4 cable arrangement...
Everyone who hears this rig always ask me a tone of questions about my rig. I got more compliments on my tone in 2 months with this board and a DSL40C than I got in over 20 years with a 2203 & 2034 cabinet.
Everything on this board is on all the time....everything except the delay and the left hand EQ. These pedals are my tone and when each one is switched on individually, the effect is very subtle. The EQ on the right is on all the time.
The delay is switched off - sometimes - for certain songs rhythm parts, but I generally have it set conservatively and can leave it on all the time.
The EQ on the left is switch one only for solos and it provides a significant volume boost...
Again....sorry to hear that you were unsuccessful.
