Well, just got the 23" Gothic Radius home...
Interesting stuff here: If I wanted to get some weird, weird sound effects simply by holding the sheet of stainless steel by it's edges and warping it in the centre. Weird, weird, weird sounds!!!!
Playing it with 5A's definitely has that trashy, somewhat reminiscent of a K with a bit more metallicky sound. Tough to explain- it sounds old and new at the same time. But it is NOT a cymbal.
I can't wait to drill it for rivets. Will it replace my Paiste Blue Bell ride? Of course not!!! Would I be comfortable playing a soft ballad on it? Yes!!! It's dry and somewhat washy with a nice, defined ping, but never gets overly washy (mainly due to the lack of mass and the fact that it is NOT bronze) but doesn't crash worth a damn!!! It is great for those of us who want a cheaper alternative to buying a really expensive soft ride that could get destroyed by a harder touch. Purists would probably scoff at my assessment... It will also NEVER be a loud sound, but it would be fine for a coffee house gig and okay in a mic'd setting.
The sound sample on the Factory Metal Percussion site is amazingly accurate. Try it- you may like it...
