I plan on getting a hellraiser c-7 fr and would like to get it set up a half step down and occasionally drop it one full step lower. I am not too familiar with a tremol-no and have no major experience with floyds. Am I going to be able to switch tunings regularly with out constantly having to set it up or should I just stay in my original tuning. I know that when you lock it you can make it dive only but once again I am not too familiar with trems in general or a tremol-no. Can someone give me an answer for this and give me a detailed explanation on the pros and cons of a tremol-no? I would just keep it in dive only for when I drop it down a step, full floating for the original set-up.
