Yeah had the same a while back. Id been using my Spector Ns2a since mid 92 and in 08 figured I need a jazz so got one in the states a stunning brand new 75 reissue.
I played this bass for 3 years and in the latter few months was really trying to convince myself this was the bass for me.
One night I brought the Spector back out and it was like putting on the nicest pair of old slippers everythig worked my tone, technique, vibe, inspiration for the music weird, but, it all realigned again...if that makes sense.
At the time of getting the jazz I was looking to "retire" the Spector as it was getting on in years and just plain wanted a new bass, never been a collector.
So I was back to the Spector till 2010!, I did use the jazz for a few other gigs but I was still struggling getting the tone and my technique out. Found all this very frustrating, having a top caliber instrument and just not enjoying it.
I'm waffling now but I recon most players would say its good to have the various basses at hand for different situations. However I chose to.... Retire the NS2a to a new Spector Wimbish model.
The jazz found a new loving owner with a swap deal for a Ken Smith.
I recon I'm just not a Fender player but funny thing is ill probably pickup a cheap jazz at some stage now that I have the start of a small collection.
