When I first picked up an instrument it was a cheap Vox stroller guitar bought of my mum's mail order catalogue for 18 guineas. That's £18.90p in today's money. Well it was 1965. I found that I picked out the bass lines to play rather than the guitar and so my love of bass was born and the quest for the perfect sound. P.A.s were small, a 2x12 per side and if you were lucky a 100w amp to power them and monitors were unheard of. Throughout the rest of the 60s, the 70s and 80s my equipment got better and better and there was still no P.A. support so the onstage amp had to fill whatever venue you happened to be playing in. It also meant that any bass going into the venue was coming from behind you and what a wonderful feeling that is. The power of a great bass tone pushing you in the back. I loved it then and I love it now and I still prefer the bass to come from the stage rather than the P.A. For me, feeling the bass in this way, is not only exciting and after all the years it does still excite me, but also aids my performance.
I suspect that you on the other hand, unlike me, don't feel the need for the physical stimulus of an amp behind you and are more than happy to have a bass sound that you can hear coming from somewhere, if so, that's great, you've saved a fortune trying to find that elusive perfect sound, but you'll probably spend it on basses if you've really got the bass bug.
