I use Logic Pro X for recording in my home studio. I have used the built in bass amp sims quite successfully but think maybe they are a little limited--just the 3 amps are simulated. I find twiddling the virtual knobs on a virtual amp a bit ... something less than ideal. I'm toying with the idea of buying a Rumble Studio 40 to use for recording bass into Logic. Has anyone here used one of these for recording bass in Logic? How were the results? How does it compare to the bass sims in Logic? Any comments would be greatly appreciated.
