LTspice Modeling
PCB Layout
About Us

We are equally comfortable with analog solid state, tube, or digital solutions for your musical electronics
prototyping needs. Consider us for your next project, whether you just need an LTspice model for either your own
 or our design, a printed circuit board layout, an assembled and tested board, or a fully functional
complete prototype ready for your booth at the next NAMM show.

Please note that at this time we are only selling musical instrument electronics
design services and OEM prototypes, not consumer hardware.
