Hey Thx !!!! It Helped ME Bt Hw I Use Ma Whammy Stick Sensitively ????? Ma Guitar Is JAVA Electric !!!!! I Cant Use It Properly !!!!
Most of the inexpensive guitars with whammy bars go out of tune as soon as you use them, i would say if you are practising at home, you can go ahead and use it, but if you play live, it may knock the guitar out of tune each time you play and use the whammy. Instead try developing skills to use the tremolo/whammy effect with your fingers.
even i had the same doubt now i got cleared i am using that to play devotional classical songs my guitar sounds like veena instrument when i use and its really wonderful to play classical with it. its so easy and give a peaful feeling
