| | | |||||
| * | remove DI box | rekado | 2012-11-20 | 1 | -456/+130 |
| | | | | | | | | | I don't really need a DI box all the time. It complicates the circuit, draws more power, and requires more space. An external DI box can be connected to the mono output for the same result. | ||||

| * | add connector for tuner output and melody insert | rekado | 2012-11-18 | 1 | -68/+85 |
| | | |||||
| * | simplify melody send/return | rekado | 2012-11-18 | 2 | -206/+242 |
| | | | | | | | | | | I no longer want to use two mono sockets for separate send and return routing. A single stereo jack for effects insert is just as fine and easier to implement. I also no longer care for an effects blend potentiometer that determines how much of the unprocessed signal is to be blended with the return signal. Controlling the effect intensity is the external device's job. | ||||

| This is a dual channel preamp in the making. I intend to use it with my [Chapman Stick](http://stick.com). You will need the [gEDA programs](http://www.geda-project.org) to view and edit these files. The [PCB editor](http://pcb.geda-project.org) is required to edit the board. | Fcgiwrap Daemon |
