(First let me start with stating that I am not a native english speaker)
With the risk of getting flamed:
This is not intended as a digital vs analog rant!
I get why people „are going ampless”. I have been crafting „my sound” using pedals for more than 2 decades. I have done this to not be at the mercy of a certain amp or cab, being able to play on any stage, thu any amp or even without an amp….. all before ever using IEM.
I have done this by using a few analog pedals: comp, Tech21 VT, Aguilar Tonehammer, Lehle/RMI Basswitch IQ/DI, Empress Para EQ, …… When I needed a second sound (pick or overdrive) I have added an EQ or an overdrive pedal) etc…
What am I trying to say?
a clear DI vs speaker signal: the DI is almost always the „better” signal for a live mix. Meaning very often a clear DI cuts better and a miked speaker is an additional bonus. That is why a sound person prefers a „pre EQ DI” as opposed to a POST EQ DI from an amp, eq’ed for stage acoustics.
Now substitute IR for speaker and you have the same issues in your DI feed.
A „clear” DI signal I understand can have some comp, light saturation and or light eq HPF/LPF, and effects like Chorus, Filter, Octaver, Delay, ….) but no excessive boost or cuts.
There was a time when I heavily relied an the TwoNotes CabM+ (digital power amp and cab simulator). This lead to some heavy eq’ing, BECAUSE I could which meant some heard work for the sound tech to get a decent clear, defined (not necessarily„clean”) sound to work in the mix.
I think going ampless with some digital solution is very hard as there are too many options available, namely ampsims, IR…… that are giving the foh and monitor guy a hard time and by this will not satisfy anyone on stage either.
When only 2 or 3 sounds are needed, a few analog pedals will be easier and cheaper.
