First of all, I started by using the Pandora PX4D and specifically the Slap Bass patch. I made sure to remove any effects processing since I was going to be doing that on my DAW i.e. Reaper in this case.
As far as to the effects the first VST effect I used was a guitar effect the RedNefTwin from SimulAnalog. Here is a screen shot of the settings used:
The second effect is the free Classic Compressor by Kjaerhus Audio. Here is the screen shot of that:
Finally the third effect is a reverb again by Kjaerhus Audio namely the Classic Reverb. BTW, the “Classic” series is a set of free , yes free and excellent VST plugins.
Check out the mp3. Its a very basic bass riff that is repeated over a BFD latin drum groove but it should get the point across as far as to the sound of the bass. It is also bass riff to one of my original tunes Maldezar.
I have started a discussion on creating bass tones on my forum.
