I believe this purchase which arrived today grants me admission to the club.
It's the EHB1506MS. It's my first 6 string, first Ibanez, first multiscale, first headless and my first experience with Nordstrand pickups!
I had tried one of these out by accident in PMT about a year ago. My friend was trying out a guitar and one of these was set up plugged into an amp. I thought it was the oddest looking bass, but was surprised how comfortable and easy it was to play.
Now that I have one, my opinion hasn't changed. Well made, lightweight, easy to play and sounds great. I've read that some others have found quality issues, but no problems so far. The Neutrik locking jack is pointless in my opinion, but not a problem for me as I have a Gibson Les Paul that I bought new in 2008 which has one and has never caused me any issues.
The look of the bass doesn't fit the usual aesthetic of the music I'm playing in the one band I'm in at the moment playing bass (Allman Bros, Dire Straits, Clapton, Christopher Cross, Steely Dan, Hall & Oates etc). However, I don't much care and I don't think my band mates or the audience will either.
I'm looking forward to experimenting with it!
