Custom 2 channel all tube handwired preamp

This project was the dream of a guitar player in the Seattle area, William Thomas Anderson. He was looking for a way to get more tone out of his rig and we branistormed and decided that a 2 channel preamp was what would do it. William needed it to be in a 1U rack cabinet, all tube and have Fender tone and Matchless tone.

The Super Knob

This started off for a guitar player in Wisconsin, William Dean. He asked for 50 watt all tube amp that would fit in a standard fender cabinet but he wanted more than just a bassman clone. After talking about what he wanted, we decided that a 50 watt version of The Knob, would be perfect. We used 6sj7 octal tubes along with 6sn7 tubes for a classic tone then 2 XEL34's in our unique KNOB output stage. It has 3 modes: clean, mild and dirty, its very touch sensitive, very pedal friendly.

This is the unit we start with...audio oscillator with power supply and capability to become THE KNOB

The Elegant Knob came about after a guitar player in Chicago heard The Knob at The Music Gallery in Highland Park. Todd Klimek instantly fell in love with the tone , capabilities and looks and wanted just one thing...a combo amp! After discussing Todds needs we decided on a compact size using the rack mount version and adding two 8 inch Weber speakers. Todd has a blog on the whole build process and he couldnt be happier with the final product.
