+1 Badass does seem like HR jazz to me too..
However, my findings when we were doing tests on the bridges for jimmy's basses were that we went though a few different metals. Aluminum, brass, steel and combinations of each..machined from solid material and potted..it took some time and alot of back and forth....Settled on a brass combo finally.. I wouldn't exactly call it minimal difference.. But i would estimate it was maybe a 15% difference..
And my original bridge on my early production LPB LG5 was a badass5. I am not sure of the material makeup of the BAdass.. It too sounded different than the "B"
The badass has weight to it or should i say Mass.. weight and mass are different things i recon.. maybe i should say density... but when you tapped on the badass it sounded different than the "B"..
What i noticed with the Aluminum one that looks exactly like the one one that he uses now. But the aluminum was very noticeable truncated on each end of the audio spectrum.. it was almost as if you had a graphic eq and lowered the deep lows and the top top end by multiple dB.. Some people may like that.. If you were listening to it you would say it had a mid bump but it actually attenuated the highs and lows giving the impression of boosted mids..
After listening tests i ran it though soundforge and took imprints of the actual freqs just to see if what i heard was really happening.> it was an education.. The bridges were identical except for material make up... The aluminum bridge also had different attack or seemed to have a different attack since the fundamental seems to have shifted..
The Brass combo seems to be more flat (if that pertains to this) sounding with a nice attack and best of both worlds...
The Bent Plate still has not been AB against the standard and i will try to get to it this week. It is on the kbp5 and that bass is very punchy.. I want to see what difference the bridge makes.. And see how much the bent plate contributes to the punch if any...
If i do get to do it this week .. i will again try it in soundforge to see what freq curves there may be if any.. Just some of my findings on that subject RE: the Allevas,, They may react differently on a bass made of Maple or another material.. I dont know..
