Hi guys! Thanks for your replies. I paid £450 for it in a shop in Manchester called A1 music in 1987 I think.
I have a few Alembics but this bass is the best to play. I once sold a bass and regretted it ever since so have no intention to sell this one.
I think I might take it to the gallery in Camden and ask if they can sort the sound out for me.
Thanks for your help!!!
Regards Alf
