So thinking my next axe will be a SAS NF or NF3, played a SAS NF 25th briefly when I was in the US and really dug it. I didn't compare against a NF3 so I've got a few questions buzzing around in my head: 1. What are the major tonal differences between the 2 axes? Mainly concerned with the different body wood effect and not so much scale length, top route vs back route etc 2. It looks as if some of the SAS NF 25ths had some nice flamed necks on them, does the flame make any difference to tone or is it purely aesthetic? 3. What is the finish on the neck of the SAS NF? I know on the NF3 it's "sunken into the wood" so wondering if it's the same on the SAS NF? Thanks!
