Well.... I find it hard to see Delano’s as being dead (you may have had a duff set), big chance it could be a dead instrument - did the sound change with a pick up change?
So all in sandberg made basses.....
I have played Delano’s in a VS, VM, 48, VT, TT.
I’ve played original Sandberg pick ups in a VS and a MarloweDK (passive)
Haussels in a TT (passive)
Black labels in a TT and TM2
Now this pick up is very subjective, for example plenty like but I do not like turdstrand pick ups, but as a generalisation.
Delano - yes more hifi, but not sterile in anyway, transparent in a good way with plenty of oomph.
Haussel - Little German manufacturer, verry meaty and quite hot mid focussed jazz pick up, neck solo’d it’s as close to a P as a jazz pick up will get.
Old Sandberg - more vintage sounding, less output, very very nice pick ups. Especially nice if you like pedals with preamps in as they are hot enough to be good on their own, but not too hot that they do not then fight with a pedal to over power it if that makes sense. Very easy to sculpt a sound.
Black labels - blew my socks off - it’s like the Old Sandberg’s with More chutzpah, very punchy, great sound - sort of like all the best bits of the aforementioned ones rolled into a pick up. Played a TM2 before and after - transformed it.
There is a basic guide - I would go for it, I think they are great.
Happy for a PM if you want to further dissect the discussion.
