I bought my perfect bass in 1977, a Rickenbacker 4001; I've acquired one or two more Rics over the years, just to keep it company.
Sure there may be other basses which are supposedly better, but I can walk into a room full of basses and not see anything else if there's a Ric there.
I do have some other brands I like (including Warwick, Status Graphite, Fender), some I like having (Kramer, Westone, Steinberger), one or two others I'd rather like in my collection/selection (Gus, BC Rich), and a couple of pricey ones I wouldn't mind for completeness but will likely never buy (Alembic, Wal).
But I can safely say that I've never seen another bass I have even thought for a moment I would rather have than my Ric(s).
