An observation, please discuss. Back in the day (70's), we were about 3 or 4 effects running straight in to loud amps. When the amps distorted though you are also distorted delay and reverb etc, not really ideal for most situations. Then Rack effects, preamp and power amps or amps with drive in the preamp and effects loops seem to become the way to go. This way the distortion happens first then you have reverbs and delays just like what would normally happen in a studio. Then people stripped back down to small pedalboards because the racks were too big and clumsy. But then comes the 4 cable methods because people were seeing the issues with effects becoming distorted. Now Pedalboards are back and modeling pedalboards as well, many times the pedalboards are way bigger and clumsier than the rack would have been to get the same tones, or the modeling rigs need support to get better tone on stage and powered monitors seem to be needed for many, weight savings starts to disappear. Ive seen some like Landau Mic their combo and feed the effects with that and have effect only cabs. Its like I have to wonder are we cycling back towards racks? Instead of 4 cable all the way out to the floor and back does it make more sense to have a nice controller brain again and keep time based effects back by the amp in a loop and only a few pedals and the controller out front? I wonder this because pedalboards are getting massively ridiculous these days and when I look at all the cabling I've even considered using something like an AXEFX at the amp and having minimal amount of pedals in front, this can work great if you have an amp that you like the drive tones from and like the amp.
