Here are three files to be used in FL Studio. This will set up a killer guitar sound. The .wav file must be in the ‘Recorded’ directory in your browser. Load up the Killer Guitar channel, then set each of the resulting samplers in the layer to an FX slot. Then load the Killer Guitar mixer file in that slot, and you should be good to go as long as you have X-Amp.
