Three years ago I stupidly traded in a Warwick '98 BO Thumb for a MIM jazz bass.
I was skint at the time and just wanted a change and hadn't played for years...
I realised I have not only lost the bass, but I pretty much have also lost all the capital I had invested in it..
I swapped a bass which was at £700 for a straight swap... saw it online at the shop for £1250 the week after..
If I know try and sell the jazz bass now I'll be lucky to get £350-400 for it... so my take home is only trade up, never trade down!
