Just recently I had these three custom ViK Duality 6s on my couch. The most interesting part about having them all together was the fact that they shared a whole number of common specs/ingredients like same exact make and model of pickups (SD Alpha/Omega), same Hipshot hardware, same body woods (one piece black limba), close enough selection of neck woods (2 indian rosewood necks, 1 madagascar rosewood), same nuts (buffalo horn), same scales (642mm/25.27″), same fretwire (stainless steel jumbo), same strings (DR 10-46), same tunings (standard E), close enough electronic components (2 exact same, 1 minus push-pull/tone control), same amp, same hands, same simple tunes.. The difference was in tops and fingerboards selection (2 had quilted maple tops that came off the same board, one burl maple; indian rosewood/ziricote/laos ebony fingerboards). So naturally you’d expect them to play and sound about the same… However, even plugged into a small half-digital practice amp (Boss Katana 50W) they all had very distinctive and unique tones/characters. Digging deeper would allow to find out how exactly the tone was affected by the variable elements but that’s a topic big enough for a full article. Here’s a little video comparison I shot at the shop, hopefully it will give you some idea of what I’m on here about:
