First post! - I had to jump in when I read about you "early starters"! .... I really wish I had picked up the Bass when I was young... but I'm 51 and just started playing 6 months ago. I have played a bunch of chords on acoustic guitar for a number of years - but never really got excited about it - I'm LOVING playing Bass, just wish I had discovered this hidden Fun Monster ages ago!
Been taking lessons for a while, although I'm taking a break just now to 'consolidate' I've got my Circle of Fifths and Major/minor scales sorted - and play along with a couple of groups of not-too-critical friends!
Its taken a while to get over the frustration of not being a Chris Squire in this time frame... I'm resigned now to learning slow and taking a few years to be at all any good... but in the mean time - just enjoying the journey!
Great Forum guys... I lurk a LOT
