Effect type: overdrive
Rated as one of the best guitar overdrives, this DIY project is the ZeN and is based upon the famous Zendrive. The board of this project is designed to fit in a 1590A enclosure or similar, but if you haven't previous experience we recommend to build the project in a 1590B or 1590BB enclosure.
1x 100pF 50V Ceramic Disc Capacitor
1x 3.3nF 0.0033uF 100V 5% Polyester Film Box Type Capacitor
1x 100nF 0.1uF 100V 5% Polyester Film Box Type Capacitor
2x 470nF 0.47uF 100V 5% Polyester Film Box Type Capacitor
1x 47uF 16V 105C Radial Electrolytic Capacitor 5x11mm
1x 100uF 16V 105C Radial Electrolytic Capacitor 5x11mm
2x 2N7000 MOSFET N-CHANNEL 60V 0.2A
3x BAT41 Shottky Barrier Diode
3x 1K OHM 1/4W 1% Metal Film Resistor
3x 10K OHM 1/4W 1% Metal Film Resistor
1x 470K OHM 1/4W 1% Metal Film Resistor
1x 2M OHM 1/4W 1% Metal Film Resistor
1x 100K OHM Logarithmic Taper Potentiometer Round Shaft PCB 9mm
1x 10K OHM Linear Taper Potentiometer Round Shaft PCB 9mm
1x 500K OHM Linear Taper Potentiometer Round Shaft PCB 9mm
1x 50K OHM Linear Taper Potentiometer Round Shaft PCB 9mm
1x NJM4558 4558 Dual Operational Amplifier General Purpose IC
NOTE: We recommend to use 9mm pots if you are going to build this project in a 1590A enclosure, but if you choose a bigger box, you can use full size pots.
1x ZEN PCB BOARD
1x 1590A Style Aluminum Diecast Enclosure
1x 3MM BEZEL LED HOLDER CHROME METAL
1x DC Power Jack 2.1mm Enclosed Frame With Switch External
2x 6.35mm 1/4" Stereo Phone Jack
1x 3PDT STOMP FOOT / PEDAL SWITCH
4x Knob DAVIES 1900H CLONE Black
1x AWG 22 BLACK HOOK-UP WIRE 1FT (30CM) STRANDED
1x AWG 22 RED HOOK-UP WIRE 1FT (30CM) STRANDED
1x AWG 22 WHITE HOOK-UP WIRE 1FT (30CM) STRANDED
NOTE: This kit is for the 1590A version, if you're going to use a 1590B or 1590BB enclosure you can use other jacks and knobs and you could add a battery clip using one stereo jack and one mono jack.
We recommend to use low profile jacks in order to gain more space but the TAYDA enclosed jacks listed in this kit will work too.
The board has enough space to put the electrolitic caps in horizontal but if you can find 100uF and 47uF 5x7mm or 6x7mm, these will work perfect in the standard position.
