I got a P bass about 6 weeks ago.
2 weeks ago I bought another one.
I was looking for a good Duck Dunn sound. Didn't like them at all with rounds - even for rock / metal.
Put on some flats and took it to my big band rehearsal...
There it was - that great old Stax / Motown sort of tone. The sort of thing I have hated for decades. But there's no doubt for the music I gig now, it is perfect.
I'm still disgusted with myself though.
(PS - the Greasebucket circuit is shite. Doesn't get as thumpy as a trad tone control set up. So they will be getting modded).
