I use the LFX-1310 all over the place:

24 effects to choose from that can be combined by 3 in an extremely light vst make for an great workflow and reliable effects for live processing.
This VST was the free plugin of the year.. in 2005.
Is there anything equivalent in the modern 64 world?
Something that's light, straightforward and comes as a direct file without installer?
