Many, many years ago I commissioned a Sei J5. My bass to end all basses. One of a series, but that is another story. I had specced it up and considered side LEDs for 10 seconds before deciding they were vulgar and useless. When I was discussing it with Martin (1st name terms) he asked about LEDs and it took me 2 seconds to change my mind. They were superb. I should not have sold it, but you know how it goes. LEDs are the bomb. I have another bass on the way with LEDs and I am childishly excited about them. When the stage hits blackout and you hit that switch they make an awful lot of sense.
