How do I get incredible sustain?

[revnice]

Hello all:

I'm trying to get sustain on a power chord that lasts for 3 measures at 180 bpm.

Here are my compressor settings:

Thresh: -18
Ratio: 8:1
Knee: Hard
Attack: 15 ms
Release: 1000 ms

I don't see anything wrong with that but it dies off after about 6 beats with hi gain or even extreme patches.

Anyone?

Thanks - rev

Can you post an MP3? It shouldn't be an issue to sustain that long at all.
