I have the A-105... I was looking for meaty bass heavy sounds for Drum
N'Bass and Dubstep.. big growly bassy sounds. I like the A-105 a lot
for this. It has a smooth character at lower settings but if you raise
the input gain past about 9 O'Clock it starts to get a little gritty.
I usually use either 3 saws or 2 Squares... and then just wobble it :)
