The electric lead that comes with GarageBand is weak
Let's create a strong heavy metal lead guitar!
Start off with an analog synth sound
This will work as the base sound for the lead
Use the AuMatrixReverb plugin to give the lead some character; as if on a stage
The sound is clipping. We'll take care of that later
Lets use the Amp Simulation plugin to amplify the sound making it more guitar like
That took care of the clipping
Use the Electric Guitar Smoothen preset on the Compressor to round out the sound even more
The sound is still a bit muddy, so use the Remove Guitar Dullness preset on the EQ
Finally add a Lowpass Filter to add sharpness to the sound
Optionally add these to the Master Track for an even stronger sound
That's it... Thanks for watching!
