Don't worry. I still play my Euro's just as much so all of my basses get pretty much equal playing time. The NS-5 definitely has a chunkier neck than the Euro's but I find it more comfortable to play and can fly around the neck if that makes any sense at all. Even though the neck is fatter, it's more comfortable to me so I really like the feel of it.
I really do love the 18V HAZ circuit though and have been messing with the different settings quite a bit. On my Euro's with the tonepump, I turn the treble all the way down since I am really not a fan of the sound but on the NS-5, I boost it a bit and have been getting a great tone.
I'm just letting you know now, if I ever get the scratch together to order a brand new NS-6XL, I'll be asking for the same finish your NAMM one has.
On the truck and out for delivery!
