Hi Sir Skunky!
Pasensya na sa limited knowledge ko, pero just thought of sharing some awesome free plugins that I've been using:
1. TC ELECTRONIC M30 Reverb
-Straight forward, great sounding reverb. Got this for free during a TC Promo. I think the link is still alive.
2. QUIKQUAK UpStereo
-Stereo Field enhancer to make the mixes sound fuller.
3. Magnus Jonsson Ambience Reverb
-A great sounding reverb with more controls and settings than the M30. harder to use lang especially for newbies. pero once you get the hang of it, its cool! I like the M30's for vocals berter though
4. Variety Of Sound Density Compressor
-A great compressor. I especially use this during mastering.
5. Voxengo Span
-Spectrum Analyzer. really helpful for monitoring those unwanted frequencies.
Hope this helps!
