I had tired of my Pearl eliminator pedal, and was using my Tama one instead, as it seems better made and is more adjustable (the one Pearl weakness is that you can not adjust the pedal angle, and every time you change cams, the angle changes). However, I love experimenting and so I bought the yellow and purple cams. Even though normally I prefer the Black round cam, the blue and red not doing anything for me, for some reason the purple cam is superb. It is in between the blue and red, and yet it is truly a different feel altogether. I usually find power cams lack power when playing short quick notes, they are powerful when blasting away, but not for quick sensitive stuff. However, with the purple cam, I found it really sensitive and a truly great feel. For the price of a cam, if you have this pedal, spend the extra few quid and try this out.
