I'm not after any one particular bass. But basically here is my problem. I design my bass sounds when I make G house/ Future house music like this:

But for the life of me I cant get my bass this DEEP.

At the moment I use square waves on massive and primarily mess with cutoff manipulation, and messing with the 4th envelope decay. I also have played around with different filters and wave shapers.

However, I just cant get it to hit you right in the soul. Furthermore, when I lower the key I lose too much body.
