I would not say
Yamaha is better then
Pearl. If anything they are about equal.
If you hated
Pearl I have no idea why you would like
Yamaha all that much better. I found problems with both brands. I like the sound of maple over birch so I stick with
Pearl. Besides they are cheaper and built like tanks.
If your band director will buy drums by color and name alone. good luck with your band program. its a ridiculous way to buy instruments.
