The amp is pretty good
The amp is pretty good and overall versatile. However, the inbuilt tuner could use improving my a digital read of each string, and the ability to change the tuning hertz as desired. The amp itself should also be able to power speaker cabinets if desired, instead of being forced into other positive grid related solutions for this option. The sound of the amp is great but could use a presence control to further dial in the tone of each amp. In addition, there should be a manual override function instead of being integrated through the spark app.
