Challenge: make a hard rocking high gain song with no guitars, only bass and drums.
This was an experiment that I didn't think would turn out this well, but I was pleasantly surprised.
Bass tracks are done with the Citrus Bass 200 and ML Sound Lab USA Bass IRs that are coming out soon. This pack is based on a Mesa Powerhouse PH1000.
The "guitar" tracks are done with my G&L Tribute L2500 5 string bass through a Brit 800, Corncob M50 and a Plexi using ML Zilla IRs.
Clean delays are a Class A 30W TB with ML Zilla cabs.
The high gain tones are the exact same presets I use on most of my guitar tracks, I didn't even adjust them for the bass. I just plugged in and played and this is the result.
