In the video, you can really get an idea of how it treats the sound when i open the top.<\/p>\n<p> As opposed to the LightBox, the Esteli has two knobs. The top is for volume and the bottom a 10k pot in the gain look between pins 1 and 8 on the IC. I&#8217;d probably recommend a 50k in this configuration, but it does make the amp really loud which i think is better for the instrument side of things. The gain of the amp then floats around 100-200 depending on where the gain is set.
