It fits! (Just)
For me it’s transformed it, with the original pickup I was struggling, the mid control seemed way too powerful, low end boom- tone suck ... and couldn’t find a setting that worked for all pickup configs.
The uni pre is wonderful - active blend, passive roll off, pick attack and I can tune the freq the bass and treble controls work on. The semi parametric mid is brilliant as I can find the setting that works for the pickup settings.
I can get a passable P style tone (75% neck, neck coil on HB, passive tone backed off, bass slightly cut and boost mids at lowest setting) different jazz tones and, well I almost bought a 1977 stingray but found tonally the Humbucker with pick attack on and no passive tone roll off got me 95% of the way there.
Honestly, I bought this 55-94 by accident, the East was a last gasp try this before selling it, I didn’t think I would ever play the bass as much as I do. Esp given it’s my first 5 string. The biggest problem is I don’t really need/want the B string!!
