There is one satellite bass marked "junior" on the bay, its a bolt on neck and while the pickups are decent i remember the switches causing all sorts of problems with poor connections. pots were ok though. As i recall a few of these had some raggy edges due to the frets not being properly finished making them a bit uncomfortable to play but at £50 its worth a punt if only to collect one. Cheap catalogue bass.
Many of these japanese and korean basses had flat bodies which made them uncomfortable to wear for long periods with the body digging into your ribs at times. early yamahas such as the SB55 and SB75 were the exception as they had shaped bodies, great necks and action and brilliant pickups. sadly yamaha did not sell them in the euro marketplace so they are rare but they do come up and they are cheap. well worth the money. over the years I have collected many basses and the SB55 is still my favourite.
