Pedal description
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.

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.     
 
 
     
Hardware                
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.
 
Important:
  • 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.
