Hi, if you can make this 2 pedals you will save a lot of space on our pedalboards, it seems like QC is more focused on the amps than the effects specifically mod, delay and reverb.
I believe amps are easier to model/implement. I was building effects in the past. To build a good sounding overdrive/distortion effect was way easier (I am still using two I built in early 90s) as to build good sounding modulation or compression effect.
Chances are NDSP is developing such effects, just they naturally require much more time for the results to be accepted.
