Cosmo:
Welcome to the club. I posted the same question when I ordered my soon-to-be-completed (fingers crossed) Further. My initial thought is that they were a little gimmicky, but the response I received was so overwhelmingly positive that I went for them. I'm getting side LEDs (the front ones really are just for show IMHO). I opted for red, (with double amber on the 12th and 24th frets), as red doesn't degrade night vision. After considering it, I elected not to get a dimmer switch as I tend to find a setting I like and stick with it on most things, so I figured the internal trim pot adjustment would be sufficient. My Further will be my 3rd Alembic and first custom. I started on an '83 Electrum and added a '76 Series 1 I bought on eBay a couple of months ago. If you've never played an Alembic before, you're going to be blown away. They are almost a different instrument unto themselves. Piano power with six strings!
