Mark, I had a C2 with smooth drawbars and Trek percussion and it was one of the best sounding Hammonds I¡¯ve ever played.. I know of other payers who have, or have played, C2¡¯s who would agree.. I found no difference between the Hammond and Trek percussion.. Trek is actually better if you like the 5th harmonic and it¡¯s adjustability.. go with the Trek. Craig
