Yes. Different guitars and amps need different knob positions to sound the same. GuitarToneAdapt models pickup output and wood brightness, then compensates so you match the record on your own rig.
Start with Bridge pickup, the amp EQ above (gain 5.5, bass 5.5, mid 6.5, treble 6, presence 3, reverb 1), and boost, compression. Then let GuitarToneAdapt compensate for the guitar, amp and pedals you actually own so it sits like the record.
