Starting out
Here we look at how you can take your cleaned-up bass guitar recordings and use amp emulation software to craft great tones.
Software enables us to record, edit, tune, shape and manipulate guitar sounds quickly and effectively, and that includes bass guitar. Today’s amplifier-modelling software emulates such classic amp rigs as Ampeg’s SVT (IK Multimedia Ampeg SVX) and more boutique offerings like Mark Bass (Overloud’s Mark Studio 2). These often include bass-specific effects pedals as well as cabinets, both contributing to the overall sound.

Step 1: Let’s start with a DI bass sound. We’ve done some editing on the performance as the timing is slightly out in places. We’ve also gone for the picked sound as our starting point because we like the brighter attack. The sound is thinner than we’d like, though, so we’ll be looking to improve that.

Applying an amp emulation
Step 2: Next, load up an amp sim plugin (Mark Studio 2, in our case). This simple patch includes a tube preamp and a 6x10" cabinet with a 1" tweeter. The sound instantly becomes bigger, rounder and closer to what we’re after. Much of the sound comes from the miked cabinet, so we’ll try and improve that next.

Mic and cabinet settings
Step 3: Although we like the sound, it’s too big. We can adjust the cabinet in a few ways, starting with mic position Far and cone Border settings. For extra attack, we could also switch to a dynamic mic. We like the sound of the ribbon, though, so we stick with that.

Compressor and chorus effects
Step 4: Now let’s adjust the sound with our pedal board. The first stop is the compressor. With a fast (lower) Attack and Release, we can add sustain to the sound and emphasise the pick sound. Some Chorus can also fill the sound out, adding subtle richness - a little goes a long way, though, so be careful.

Adding distortion
Step 5: Our amp model is pretty clean, so to dirty up the sound and add some edge, the distortion pedal is our next port of call. Again, care is required with this, so we only add the tiniest amount of Gain and keep the Tone setting well clear of excessive high frequencies.

Blending the DI signal
Step 6: Our plugin lets us blend in the original DI signal, and we want to try phase shifting it as well. We copy the audio onto a new track and load up our phase alignment plugin. In the audio example, you can hear how the sound changes as we rotate the phase, and then (from 27 seconds) our final sound.
