Analog Synth

The biggest electronic project I ever did. Actually, I started in 1980 but couldn't make the pcbs then. Retried in 2000, and this time I didn't give up... More details

Preamps

Discrete JFET Bass Preamp

My bass preamp. Perfect sound with three FETs (and some gimmicks). More details Schematic

 

 

Onboard JFET Preamp

Onboard bass or guitar preamp. FET based with two volume knobs and a one-knob bass/treble-boost/cut-mid-switch tone control. More details Schematic

 

 

Other Preamps I built:

These FET preamps are based on the well-known design by Don Tillman.
	Here is my version of Don's Discrete Guitar Preamp. I use a 50k pot as a master volume instead of the fixed 51k resistor in the original. Good for P-Bass after the tone control. Schematic PCB Components Layout
	This is a preamp cable exactly like the original, except I added a mute switch for easy tuning and change of instruments.

 

Other Projects

Bass Amp with Cabinet

Building a bass amp from scratch. Will take some time. More details Schematic (soon)

 

 

Another Bass Amp

Had this 100W power amp lying around for years. Combined it with my JFET preamp. More details Schematic (soon)
