I purchased in 1972 a new Paiste Giant Beat 24" ride cymbal and performed with it for about 10 years before selling/trading it. The size was the primary reason I tired of it - more difficult to pack and transit than the standard sized cymbals. Secondary reason was it's "roar" once in motion, being the kind of cymbal useful only in high volume stage use. However, I found the overall 'timbre' and sound of the cymbal quite good, and its 'ping' definitely could be heard over stacks of Marshall and Hi-Watt amps.
Early this year I acquired a new Paiste 502 Plus 20" medium ride cymbal. In my opinion the overall characteristics of the cymbal are a strong reminder of the above mentioned Giant Beat. The sound has the same general timbre and piercing stick ping as my old Giant Beat, but I find the bell 'acceptable though rather less responsive and 'weak'. When 'whacked' with the shoulder of a stick on the bow while riding, the 502 fails to punctuate the rhythm and articulate a crash - it just keeps up a loud uncontrolled spread.
In short, I think the 502 Plus does closely resemble the overall sound character of the Giant Beat line, especially when considering its a lower priced line manufactured in Germany using very high tech computerized methods. This being said I never recommend buying cymbals without first playing and hearing them to determine whether or not they match up with your set, style of music(s), and of course your other cymbals with which they will be set up and played. Hope this helps! :cool:
