Looking into this more, it seems there are more differences between models than I had thought.
The three Jabba models I’m most interested in are the Hadrien Feraud JJ5 and PJ5, and the Federico Malaman P/MM 5.
The HF sigs have 18mm string spacing at the bridge, standard jabba is 19mm.
The HF sig has a 20” fingerboard radius, FM is 9.5”.
The sig models have a 3 band pre, as opposed to the standard 2 band.
The body woods are different (sassafras vs ash/spruce), I have no real idea if that matters.
To my ears on YouTube, the HF models sound richer and more 3D, the FM more bright but not as rich.
I generally prefer 20” radius and 18mm string spacing.
The P/MM combo seems interesting in concept.
FM model is cheaper.
FM has Mayones velvetrone pickups, HF have Delanos.
Gregor on BassTheWorld seemed to love the HF JJ and FM models a bit more than the HF PJ.
The HF JJ model in antique brown is the most attractive to me.
Sometime in the next few weeks I’m going to take a trip down to PitBull in San Diego and check out all three models, plus any other Jabbas they have.
That will clear up a lot of things, and I’ll report back. But, does anyone have any comments on the differences in how these basses might sound and feel in rock/funk/other contexts?
