I have a Korg DTR-2000 tuner, works great on my Aerodyne P pickup. Just got a Bob Glaub and it sounds incredible, I'm tickled pink, but it simply does not register on the tuner. Sometimes (rarely) I can get the A D and G to pick up but never the E. I've tried putting the tuner in chromatic mode and bass mode. I thought at first that my tuner wasn't plugged in so I connected my bass directly to the front of the tuner The guy I bought from put light strings on it... I think the playability was bothering him cause he's not a big dude, and this sucker is heavy and the neck is wide. Maybe putting normal strings on it would help. Any tips? It's very frustrating. I don't like tuning by ear because my ear is too subjective. On a possibly related note, I have noticed that my Ashdown "sub-harmonic" octavizer thing sometimes picks up a weird frequency instead of the octave as well. It's odd and it makes it unusable on low notes.
