[Chaotic Kittie]

I've tried to remember it now, and tried to look it up, but I can't find out HOW you write this chord out!

I know it's like a 9-chord but with a sharp 9, but.. how do I write it?
It can't be i.e E#9. O.o

[si16]

E7#9 is how it is written CK. It was most famously used in Purple Haze with a fingering of

E
B 8
G 7
D 6
A 7
E 0
