Need some tools, prefer freeware if poss. Recommendations?

A nice, low CPU light reverb (ableton's verb sucks balls)

A big, rich, cavernous reverb (got nebula, but need more)

A good delay unit (might be being a spaz, but can't get the result i want from ableton things)

A good spectrum analyser / frequency analyser

Thousand thankyous BOA crew!
