theres almost no sustain, but it sounds righteous. I like to run it through my pedal to give it some tone control and add some reverb to make up for the lack of sustain, but other than that it does sound really good. It almost sounds like a synth guitar or something because its so clean-crunchy (ill use distortion on pedal and amp)
also the you can turn the gain up on the eleuke and it gives it this really nasally tone, similar in my opinion to the bridge pickup of a telecaster where its really hot.. but it sounds really, compressed.
