hey guys, ive been searching latley for a really solid bass synth vst plugin, like something thats fairly easy to use and has good amount of different sounds and whatnot. I'm mainly looking for something that can produce some seriously low earth shaking kind of bass
Relatively any synth capable of producing even the most simple waveforms can make low, funadamental, earth shaking bass.

Your DAW should have some included that are more than adequate.

If you aren't using a DAW, there are tones of free VA modelling VSTi's for download that'll do fine.
