I'm having trouble finding a suitable tuner. Most seem designed for guitar rather than bass and a few I have tried have difficulty with low end (especially as I tune to drop Bb). The only really reliable one I have used is my guitar player's Boss Chromatic Tuner pedal - but I don't really want the hassle of an extra pedal, especially as I will pretty much stay in tune all night and don't need to tune between songs unless I bump a tuning peg on somerthing which is rare. I just need something that will give me a quick, hassle-free tune up before I go on stage - a "clip on" would be ideal, but the ones I have tried struggle with bass frequencies. Ideas?
