PROJECT NAME
AZIMUTH
BASED ON
Hermida / Lovepedal Zendrive
EFFECT TYPE
Overdrive
PROJECT SUMMARY
The first overdrive that attempted to replicate the tone of the legendary Dumble amplifiers. A favorite
of blues guitarists, and with its low parts count, a great project for beginners.

Page 9: Pcb Assembly Overview
PCB is upside-down, everything is making contact with the work surface and is held in place. So, you will start by populating the resistors (the lowest-profile components), followed by the diodes, sockets, film capacitors, and finally the electrolytic capacitors. AZIMUTH DYNAMIC OVERDRIVE... -

You’ll use this same technique for most of the other components as well. If this is your first time soldering, watch tutorial videos on YouTube and make sure you get it down before you begin. You don’t want to practice or experiment on this board! AZIMUTH DYNAMIC OVERDRIVE... -
Page 11: Diodes
The germanium diodes included with this kit have been individually tested and verified as working. Unless they arrive damaged, free replacements will not be offered, so please be careful! AZIMUTH DYNAMIC OVERDRIVE... -
Page 12: Socket & Ic
ICs may have two different orientation marks: either a dot in the upper-left or a half-circle notch in the middle of the top side. Some ICs have both marks. This shows which way the IC should be rotated when inserting it into a socket (the socket also has a half-circle notch). AZIMUTH DYNAMIC OVERDRIVE... -
Page 13: Transistors
You can just solder them directly to the board. Just be careful because they are very static-sensitive. Bend the outer leads to hold it in place on the board. Then, solder them and clip the leads. AZIMUTH DYNAMIC OVERDRIVE... -
Page 14: Capacitors (Non-Polarized)
Bend the leads at an angle to hold them in place. MLCCs and box capacitors are not polarized and will work in any direction. To keep things neat, though, it’s best to put them all facing the same way. AZIMUTH DYNAMIC OVERDRIVE... -

They do fit pretty tightly in the holes, though, so press firmly. There’s also a 4-pin header on the I/O board that we will do in a later step. AZIMUTH DYNAMIC OVERDRIVE... -

The longer leg is positive and fits in the square pad. These are the last of the on-board components. Now is the time to go back to page 12 and insert the IC into the socket. AZIMUTH DYNAMIC OVERDRIVE... -

Red is positive (+), black is negative (-). After soldering, pull it tight. For even more strain relief, you can thread the snap through the loop to form a knot. (not shown) AZIMUTH DYNAMIC OVERDRIVE... -

You’ll need to hold the bezel in place when OUTER WASHER tightening the nut. The top of the bezel is fairly MOUNTING NUT sharp, so try using a rubber band for grip instead of pressing your finger against the bottom. AZIMUTH DYNAMIC OVERDRIVE... -

However, Aion FX projects are designed to be extremely easy to remove from the enclosure for troubleshooting, with no desoldering required—so with these kits, it’s actually much easier to “box it before you rock it”. -

Note the use of two mounting nuts on each of the jacks, one inside and one outside. The inner nut acts as a spacer to set the DC jack flush with the outside of the enclosure. The inner nuts should be threaded as far down as they can go. MOUNTING NUT OUTER WASHER LOCK WASHER MOUNTING NUT 125B AZIMUTH DYNAMIC OVERDRIVE... -

Last, just close the panel on the back using the four screws. Before that, though, grab a permanent marker and write your name and the completion date on the inside of the back panel. This is an accomplishment! AZIMUTH DYNAMIC OVERDRIVE... -
