This question refers to the document located here:

http://www.diystompboxes.com/DIYFiles/up/Build_Your_Own_DS-1_Distortion.pdf

I'm interested in building the True Bypass DS-1, but I'm unsure of the orientation for the PCB. I'll be using the Press n' Peel blue method to make the PCB. On page 9 of the document, it says "Ready to Transfer", but the text on the PCB isn't reversed. I don't know if I should reverse the image or print it as is. On page 4 of the document, the text is reversed on the PCB image for the Stock DS-1. This adds to my confusion.

If you look at the part of the PCB where the IC goes, pin 1 (the top left pin as you view the IC from above) is marked by a square pad.

Print the transfer as is. When the PCB is etched and drilled, the square pad will be top left when viewed from the component (non-copper) side.

an excellent question ... and welcome to the world of PCB DIY ! .... ( i don't mean to sound con-descending )

there are only two results that you can get .... either the PCB will come out the right way, or it will not ...

in either case, you will learn something ... and this ( the learning ) is extremely valuable ... as someone wiser than I once said,
knowledge is power ...

tip #57:  keep a diary of your DIY experiences ... the victories and the temporary defeats .... that way, you will develop your own solutions to your personal DIY experiences

Thanks for your help. The first PCB I ever attempted was from "Electronic Projects for Musicians", and I didn't know that I needed to flip the image after scanning it. Since then I've been really hesitant when making a PCB, because I don't want to waste any supplies. I've usually relied on checking the text on the board, but checking the IC pinout is a method that I hadn't thought of.

UPDATE:

I printed the transfer as is. I built the DS-1 with the Keeley seeing eye and ultra mods. The PCB design makes these mods really easy, after populating the PCB you simply wire in two additional on-on toggle switches. However, since the board is so small, you need to use the smaller 3.0 mm length resistors. I ordered the 7.0 mm length regular sized ones. I was still able to populate the board, but the resistors don't sit flat.

I think that the DS-1 sounds pretty poor by itself, but sounds great in front of a tube amp. I'm using it as a clean boost (volume maxed, distortion very low) in front of my modded Marshall JCM 800.

Anyway, I definitely recommend this build to anyone else, provided they use smaller resistors and use the DS-1 to push a tube amp.

Glad you got it figured out!  That's one pedal I'll never build, though--I buy used DS-1s for ten bucks and spend another three bucks on parts to do the Electric Ear-Candy mod that, in my opinion, sounds much better than the Keeley ASE/Ultra mods.

What's the "Electric Ear-Candy mod"? I couldn't find any information online.
