-Distortion. (distortion adds a lot of sustain and actually compresses the tone on its own)
- Compressor (But even better, look at the Compressor/Sustainer pedal from Boss)
- Gain. (The more gain you have turned up on your amp, the longer your notes will sustain).
- Guitar. (some guitars have crazy sustain while others have very little. For example, Gibson Les Pauls sustain much longer than most Jackson guitars. My Ibanez has really good sustain too)
So are you playing with a clean or distorted tone? What kind of music are you usually playing?
