Mouser parts spreadsheet

Since this is such a complicated build, I created a

Over 95% of the parts can be obtained from Mouser and their prices are great. I spent a great deal of time

selecting the parts, and the PCB layout is designed around them, especially the boxed film & electrolytic

capacitors, so by using this spreadsheet to order, you know you are getting the best possible result.

For international DIYers, Mouser recently upgraded their international shipping options, so it's very likely that

you will be able to get free shipping with a project this size. Their prices are very competitive as well.

The BOM does assume you have zero parts on your bench, so you may be able to save a few dollars by

comparing the spreadsheet with what you've got already and removing what you don't need, especially

hardware like the power jack, input/output jacks, and IC sockets. But again, I would strongly recommend

using at least the exact capacitors from the spreadsheet to ensure they fit. And while you could save a bit

of money by using your own resistors, I guarantee it will save a lot of potential mistakes to receive them all in

labeled bags!

However, with that said, I have to give the disclaimer that this spreadsheet is being provided only as a

convenience. You are responsible for checking through the parts to make sure they are the ones you want,

and Mouser is responsible for sending you the correct parts. I tried to pick high-availability components from

well-known manufacturers that are stocked in large quantities, but with 75 different parts, it's likely that one or

two of them will be out of stock at any given time. You will have to find your own replacements if that happens.

Checklist

I have tried to be as thorough as possible in this documentation, but the upshot is that by providing so much

information, you may miss some of the most important details. Here are the high-level things to make sure of

before turning it on for the first time:

• I am using an adapter that produces 9V AC, not DC.

• I have marked this adapter in some way so it's not going to be accidentally plugged into another pedal.

• I have triple-checked the wiring against the provided wiring diagram.

• I have ensured that the wiring is neat and that the wires are as far away from each other as possible.

• I have ensured that all of the potentiometers have some sort of insulation protecting them from the

board, especially the 100kC dual pot (which doesn't work with the standard Alpha pot covers or the "pot

condoms" sold by some distributors).

• I double-checked the orientation of the LEDs before soldering them in place.

• I compared my populated PCB with the photo on the project page (including jumpering CX1, the

capacitor in the tone stack of channel 1).
