New experiment
The goal is not to reach the mic tone but to get a better pickup tone. Still dry and direct but with less quack.
I use HX native (Line 6 Helix plugin version) to correct to the maximum the tone with parametric EQs & Shelfves. (5x3 PEQs + 1 shelf EQ)
The goal is that the IR carries the less correction, mostly do phase correction and remain short.
I added a crossover. Everything above 1Khz gets a shorter IR (512pts), in order to have less high frequency spikes and metallic tail. Everything under 1 KHz gets a standard 1024 pts IR.
Guitar: Martin 00-18V + Goldplus pickup (a.k.a Fishman matrix)
1) external mic SM57
2) raw Pickup
3) Pickup + 2048 pts IR (my current go-to process very mic-like)
4)
New process: EQ + IR + crossover (512pts IR > 1KHz, and 1024pts IR < 1 KHz)
5) raw Pickup
4) is the new process. It's string focus and less quacky than the pickup.
I know Jon will say that I found a very very complex way to imitate his recipe combined with a high pass filter... (which is very dry thanks to its hidden blend).
At least this complex way is mine
