Much as I hate to add anything to my hookup, I'm thinking about using a pedal tuner. The Boss TU2 seems popular but I read that it doesn't offer true bypass so the signal is slightly altered even when the pedal is switched off. I've never tried one but just knowing that bugs me. I recently tried an Ibanez LU20 tuner. I like the design and it claims true bypass. It doesn't have a designated "bass" setting but it works fine at home. At gigs it sometimes has trouble tracking. I think it's from hum in the lines. I'm using the Squire Classic vibe 50's P bass which is a single coil so it does develop hum if there is a lot of track lighting or for whatever reason. Any pedal tuners particularly good for bass? Gotta stay under $100, prefer under $50. Reports on specific models, good or bad, appreciated. Thanks!
