Here is a video I made tuning my toms to perfect 4th's using the Tune-bot A few quick points 1- These heads were replaced over a year ago when I recorded an album. They have been used almost daily for a year and still worked out pretty good. 2- I tuned my drums over 4 days ago and have played a lot so they are not in perfect tune now. (still sound good) 3- I did minimal processing. There is a slight limiter/compressor on the main channel to prevent clipping. I put some small EQ on the toms to make it represent the natural sound more. There is a dip at 500hz, and a small boost around 100-200hz. as well as 6000 I think. Noting too crazy. It sounded fantastic while playing these in the room. I am sold on tuning to specific notes now in the same scale.. I'm going to try many more combos. Keep an eye out for a snare video as well.
