The PS3 is out for fabrication, soon to be tested and released. It will be about 19mm x 29mm, and use around .75mA of battery power. It has a single filter connector, and can also be used with a dual pickup bass when it is desired to have a traditional selector switch or blend before the preamp. It should sound great with an FQ filter to replace a standard tone control, or an FS or even FV filter for a greater variety of tones.
Please post sounds clips so we can hear the character of the different preamp options.
