Well, I ended up buying the fretless Revelation RBP65, and fair do's it's bloody lovely! The bass came set up from Fretmusic.co.uk -£150 delivered. Sweet.
It's build quality is definitely above both the Vintage V4 and Squier Vintage Modified Precision I have owned. Everything works as it should. The Entwistle NPXN pickup is fantastic and the tone knob actually has an astonishing range, all tones usable.
It came strung with a really nice quality set of flats, .100 -.40 as far as I can tell. The weight is good at 8 1/2 lbs, perfect balance and very resonant when played acoustically.
For 150 notes, it's bloody silly really! Oh, and I actually really like the headstock too - a big raspberry to all the naysayers! 😝
It's nicely sculpted, I like that it's different.
The colour in person is more faded Fiesta red or coral/salmon pink than it looks in my photo.
I'll do a proper review after I've gigged it for a while, when the honeymoon is over.
But, upon first impressions, this Revelation is a beautiful bass. Good enough to be my number 1, let alone back up bass.
