It's a free world, but as someone who has owned most of the popular blenders and was responsible for the impedance buffer/blender from Barge concepts I stand by my convictions.
But there are many sides to this coin, pedals with a clean signal through like say the Assmaster fine, part of the pedal, part of the circuit and the sound.
Using something like an LS-2 to blend a fuzz with an octaver this is parallel fx processing not blending.
Running always on fx blended with your clean to get your sound then you are likely doing something wrong in my opinion (humble opinion)
For example I see guys complaining that the SFT inverts your phase so you can't blend it, well why do you need to its designed as a low gain od if you need more clean signal with it, lower the gain or buy the pedal that sounds right without the faff.
I think Shep was hoping for the debate to be on his blog for the drama and the web hits so happy to discuss this anywhere.
While it was a sweeping statement it was aimed at the less fx savvy that seem so keen to go hmmm my ODB-3 doesn't have enough lows, I should buy an eq pedal for it, then hmm still not right I should buy a blender for it and it's just the wrong approach.
I use to use an always on OD this was because I was using the wrong amp, as soon as I got a tube amp I ditched like 3-4 always on pedals. Now I take a very uncompromising approach to everything so maybe if I was always flying to gigs, had back trouble etc and I had to have a small light amp then these solutions are more acceptable.
So with that said all I have left to say is FIGHT FIGHT FIGHT
