Always regretted sending my Fender Modern Player Short Scale Jazz back to the store because of faulty electronics, but by then it was sold out and I never found another comfortable shortscale bass like it since. I bought an Epiphone 'Allen Woody' Rumblekat instead and I like that bass for its raw powerful sound but ergonomics-wise I prefered the Fender. I also bought a Ibanez Mikro bass recently but felt it was too small for me and a bit toy-like.
This JB Mini, sold at Musicstore in Germany, plays and feels very much like the Fender MP shorty although the J&D has a satin feel on the back of the neck. It's roughly the same size as your typical Stratocaster. The neck profile feels like a normal sized jazz bass. Routing under the pickguard is nicely done so you can take it of for a jaco-jazz bass style look. There is very little neck dive when playing it seated but it's not noticable with a strap.
This particulair JB mini weighs 3.2 kilo. Rehearsing with it for 3 hours yesterday was no problem! My back really likes this bass.
Not much to be found on the Jack & Danny JB Mini other then a review in German with soundsamples, which can be found here: Invalid Link Removed. To me the stock pickups (which measure 90mm for the neck and 94mm for the bridge in width) sound fine but I guess they're standard size so maybe I'll change them for something with a bit more note clarity and/or seperation.
Also, I've done nothing to it other then tune it when I unpacked it but I feel that the A string lacks a little punch. Maybe it's the strings?
