In other words, the "fat sub" issue is maybe coming from your instrument, or maybe it is your speaker/room setup? Getting a good sub from your instrument really should not be problematic. The "fattest" subs are often primarily a sub sine, or sub triangle.

Very true. My actual fave subbass patch has actually caused physical damage...mind you, it was feeding into a 20 kW array of bassbins, which might have something to do with that. But what did I create this astonishing, pounding, tactile bass with, you ask?
A Casio CZ101.
Which pretty much proves another salient point: modular isn't always the right answer!
