Do any of you guys use a stomp box style tuner with upright that works great? I have a Boss TU-2 that I use to mute, but I typically have a clip-on tuner on my bridge I use to do the actual tuning. On occasion I run into issues in clubs where either the house sound is vibrating through my bass, or the other guitars and such are doing much the same. It renders my clip on useless. However the TU-2 doesn't seem responsive enough to do a good job with DB. What are you guys using?
