I've found Lulls, like many brands, to vary in tonal qualities and it feel to me that the pickup choice can make a real difference.
I've owned five now and only one has really stood out for me and that's the one I've hung on to. Some of the others have had all the ingredients I tend to look for in a bass, light wright, well built and finished, slim necks etc (hence why I keep buying them!) but when I've played them for any length of time they've lacked a bit of character and sounded a little bland
The one I have is simple passive P with a custom wound pickup and a J neck with blocks and it works really well as modern P and does a decent impressin of a more vintage tone if you wind the tone back. I've gigged it a few times and always enjoyed it right up until last week when I really struggled to get a sound I liked at a difficult venue. At my previous gig I'd taken my new Sadowsky NYC J and I was really missing the bridge bite and a bit of active boost.
After owning a few that have, ultimately disappointed me, I'm not sure I'd buy another one 'blind' without hearing it properly first.
