Good day forumites... Fired up my DAW, tuned my Tele, plugged in the Nady 201 and the battery is dead so I need to head out into the world for more of them. A couple of questions: 1) Don't know if it's necessary but I've always taken out my 9 volt battery from my axe tuner and my Nady 201 wireless after I'm done tuning or playing. Thinking it minimizes drain and maybe having it last longer. My Nady wireless does seem to suck up juice but maybe I'm playing more than I think I am. Your thoughts?....factoids? Am I being ridiculously retentive here or do some of you do the same and tend to think it is a good general habit? 2) I'm not close to a Fry's to get the name brand 9volter's and thinking of trying the Radio Shack/Target brands. Your thoughts?....experience? Are they really pretty much all the same these days anyway? Thanks for any G2....a good day to all.
