Today, I bought a pearl p902 double bass pedal with a white Evan's bass drum head. Where? Off of amazon. But, I did play it before I bought, just my local music store had the prices jacked up. I wanted to know from the professionals- and possibly other beginner double bass peeps if this was a good buy for $140. Bass drum head was $44 dollars. It has a porthole, buy not sure of I was ripped off.
