This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.

Walrus Audio Mayflower

Here's the Walrus Audio Mayflower, which is essentially a hybrid between the Tube Screamer and the Timmy (which has its roots in the TS already). Originals use a second dual opamp for buffering the voltage divider, which in this instance seems to just be unnecessary, so I've omitted that.

    1. Yes to D1-2. Try 2N5088 or 89 for Q1-2.

    1. I use 4007 instead of 4001. would it be problem?

    2. The 4007 is fine. Does the effect work? Or does the IC just get hot? Have you tried other ICs?

    3. The 4558 just gets hot without produces any sound.

    4. Then you've probably got a short from the pin 8 to one of the other pins.
