After nearly 20 years on 6-strings (an Ibanez, then a Yamaha TRB-6) an engineer bought his new American Standard Jazz to a session. I played it on a couple of tunes and within 6 days had bought a 2010 Highway One, to which I added a Hipshot D-tuner. That was just over 2 years ago and I can honestly l say I have never been happier with a bass. It just seems to work on anything.
So embrace the slab - it looks tiny on me (compared to the TRB)!
Keep 'em peeled for a Highway One - they seem to go on here for about £400-450....total bargain.
