I was at my buds guitar shop and seen a cool bass,it was a odd-ball name one that i have'nt heard of before. it had the regular controls for a P&J pick-up configuration and 3 more dials for learning purposes.I'll explain,there were little lights up and down the neck on every frett/note,and the dials controlled what notes,chords,scales,arppegio's you wanted to learn.you would select the musical lesson you wanted to learn by turning one of the knobs,it would then lite up the correct fretts to depress and VIOLA ! the lesson lite up on the frett-board. showing exactly what to de-press to get the correct sound wanted. COOL NO ? I thought it was a nifty(nifty ??)idea,it would definately make learning notes,chords,scales,and arppegios easier to learn,even more so if one was self learning.i thought it was different,and i never came across or heard of one like this before.
