I got an Copilot FX Antenna 2 yesterday and phew does it rock!
The LFO makes a huge difference, being able to sweep through the frequencies or add a level of modulation of its own by really cranking it up.
I heartily recommend it. Anyone who enjoys making music that sounds like it is coming out of outer space on an old tube radio or that sounds like they just got their eardrums blown out will love this thing.
Oh, yeah, one thing I haven't messed with yet is it has a whole bunch of jacks that enable expression pedals to control various elements. can't wait.
