Aye. I've used it at 2 shows. For bass, you want to increase the delay a little bit for sure. I like the 5k pot, but already had the 10k installed.
For bass, once you find that perfect setting for you, you go from flat to gigantic godly overtones!
I used a TL072, hence the 100k pot in place of the 470k. I haven't un-ductaped my pedal to pop in an NE yet, so can't report on that. I rode my bike to the store to buy parts, came home and had it boxed and working and ready in 5 hours, with only an hour to spare before we had to be at the bar. Used it in an outdoor setting at the last one, and it is awesome. If you are outdoors, you can increase the depth a bit more without busting through over the top of the guitars.
And, lastly... absolutely no bass cut! I breadboarded mine with .022's in the audio paths, but I built it with all stock parts plus my mods to box up. I have a "super-fat" DS-1 that is basically my big OD. It increases the bass without destroying too much of the punch, still has the DS-1 grit, but bigger. This goes in front of my LA, and I only get the most minor bass cut out of it, which actually just seems to add to the overall tonal qualities.
Of all the things I tried, the ONLY one necessary for bass is the delay mod. Just a 5k pot. I wired mine so I could (next build) use the stock jumper pads from the layout. I just used a DIP strip on this one, but kept mods simple to work with the stock PCB.
