Elberon amps and pedals come directly from the Granger family nexus of engineering and creativity. It’s a wonderful thing to see and a pleasure to know those guys. They clearly love the entire process of working closely with the customer to handmake original gear specific to their needs, and each piece is unique and tweakable.
For example, the GTO overdrive has an adjustment for the sensitivity of the gain knob inside. In this way it is extremely versatile and can be used for a variety of instruments. I love using it with both my Nord Electro and Moog Sub 37 to get grittier, overdriven tones without too much distortion.
