well, i just got my 6 space rack, so it's time to finish off the rest of the pieces. all i need is a power conditioner and rack tuner. for the power conditioner i think i'm going to go with the RP-8 - $50 bucks at mf.com. i don't need lights. for the tuner, i really can't see myself spending DTR kind of money on something that just tunes my bass - it doesn't have to do anything fancy-pants. so it looks like there are plenty of these on ebay: Sabine RT-1601's. seem to go for around 60 bucks or less routinely. not pretty, but do they get the job done? who here has used one of these? can they accuratly identify a low b?
