Profile Info

An avid musician, Karl has created the Varying Valve Voltage! His invention is a guitar amplifier with a power varying control, allowing you to decrease the volume but keep the amazing sound the same.


What inspired you to create your project?

I am a musician myself and something that often annoys me is that I can’t get the same sound at low volumes than I can get at higher ones.


Who influences your tech/innovation?

My desire to keep improving things and learning is my biggest influence.


What is the best thing about the ASB Bright Sparks competition to you?

The competition gives you a chance to try and do something really spectacular. Whether your project wins or not, it’s a great opportunity to try something new and unique.
