The Gretsch Junior Jet II bass sounds nothing like any other bass on the market. It has some of that classic P punch, a bit of J "twang" and lots of T-bird growl but it's quite original in its own right.
I prefer it strung with Ernie Ball Regular Slinky strings (2832) and occasionally with Pyramid Gold flats. I also fitted a Hipshot D-tuner (H20600C) and it takes a low D with no problems at all (at somewhat high action).
The bass is comfortable to play, much more so than my bulky old Gretsch Broadkaster bass used to and due to the short scale it's easy to get some nice string bending going, even at the lower frets.
The only remark I have is that it could have a bit of a body shaping to it but I guess you've got to justify the low price with a few drawbacks.
All in all this is an absolute steal for the price and a great looking bass too, the finish and construction are flawless.
Pairs well with the Tech21 Bass Fly Rig so this is my smallest, lightest and still best sounding setup, aside from going all tube of course but that's incomparable by nature ;o)
