DIY Zendrive build | PedalPCB Mahayana PCB | Real-time | Demo

A quick demo and real-time build of a Harmida Audio Zendrive circuit clone using a PedalPCB Mahayana PCB. I bought all the parts from www.Taydaelectr... to put it together. This is a great sounding overdrive without harsh tones. It seems to pair well with clean Fender amps!

You should get a resistor bend tree...aka Speedy Bend- Resistor Lead Forming Tool , I see available at Probe Master. It makes loading a board so much faster because you can prebend cap and resitor leads then just plug them in. Wow, the Tayda prices look like they're from the 1960's. Looks like I'm going to have to stock up! I hate the blue resistors!! I can't read the stripes for crap. I built all of the Electronic Projects For Musicians book projects back in the 80's. My dad worked in electronics so I etched all of the PC boards and had all the quality parts I needed. Three great pedals from that book are the Phase Shifter/Vibrato. Tube Sound Fuzz, and Preamp. Oh' the Super Tone Control was also great. The phase shifter on vibrato mode has an amazing slow sweep and great wide frequency shift. The Preamp is a super clean 10V increase. It allows you to take all of your old dynamic vocal mikes and turn them into the best recording mics. I really love the EV-676 through it.

Do you know if 22 or 20 gauge AWG wire would be suitable for wiring? Edit: I just noticed that the grey wire is labeled as 22

[@MichaelGovers]

A very nice tidy build, thanks for sharing :)

[@MrBeblis]

Try AD712 or opa2604 chip, these are even more hifi chips and true to the original

[@russellesimonetta3835]

You should do a zen drive dual pedal,,, just for fun! You could talk us through how to join a dual pedal. You could also build a simple buffered switching unit.

[@TheToneGeek]

neat idea!

[@russellesimonetta3835]

@@TheToneGeek yeah zen drive did a dual pedal,,, why not you?? And for the switcher? A simple long narrow box with five ,six, eight switches with led's to control your pedals.

[@dancrandall2058]

I was just printing the shopping list for this pedal when I saw this video! I was looking at the Aion pcb, though. I wonder if it’s fairly similar...

[@TheToneGeek]

Nice! The Aion looks to be the same 😎

[@dancrandall2058]

That’s exciting! I’m torn as to which chip to use. The Aion recommends the NE5532P. I know JM used the Zen on the WTLI era, but I’m not sure for which songs/parts.

[@TheToneGeek]

@@dancrandall2058 try both chips! Cheap enough

[@patrickbenoit9417]

Hi, I'd like to build it. But before i'd like to know, if there are testing points (Volt), just to check good values, and avoiding problems, due to bad solder or anything else. Thanx

[@jordanfreeman4170]

I'm not sure if anyone can answer this but, what is the difference between a 100p and 100pf capacitor. The kit I have came with four of the same and it calls for three 100pf and one 100p, I just don't want to mess anything up.

[@TheToneGeek]

Those are both the same. You're good to go! Rock on

[@jordanfreeman4170]

@@TheToneGeek Dude thank you so much, I have re-watched this video a million times and it has been so helpful. Particularly the wiring portion. Hopefully my not so Revv 4 is good to go soon!

[@TheToneGeek]

@@jordanfreeman4170 you're most welcome. I glad you are enjoying your pedal! 🕺

[@ryanmelvey8764]

really cool build. thanks to your videos i have built 6 pedals so far from pedal PCB. your tayda walk thru video was a huge help. question for you... how do you know what ICs you can swap out?

[@TheToneGeek]

Typically dual op amps have the same pin outs. The only way to really know is to check the data sheets (or Google to see if anyone else did what you're trying to do) Thanks for your kind words! 🙌🏻

[@JPDESS]

Hi like your videos, why dont you show us how you do your art work for the enclosures in your videos. Thanks for sharing !

[@ajmaxx1793]

A very clean build. I am planning to build this and this will help a lot. Do you remember what knob size did you go with? Most knob sizes available at Tayda seems very big for 125B enclosure.

[@TheToneGeek]

Check out lovemyswitches as I believe I got the smaller size there. Thank you for your kind words!

[@trevormartin7148]

I'm looking to do this build for my first project but I can't find the op amp in stock at a decent price. Is there a different one I can use on smallbear or tayda in stock?

[@danorr6555]

Your clean tone sounds amazing! What is your clean setup in this demo?

[@michaelpalermo6227]

What size LED fits that enclosure?

[@russellesimonetta3835]

Easier to do 3 or 4 components at a time??

[@TheToneGeek]

it could be!

do you have a link to the enclosures?
