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.

Run Off Groove Ruby

Got a request for a headphone amp, "for those of us who hit their peak inspiration when everyone's asleep." Being guilty myself of waking up my 1 year old son with a Peavey Classic 50 with the volume only at 2, I thought this was an excellent idea. So here's ROG's Ruby–a 386-based amplifier that can easily fit in a 1590A, or even an Altoids tin. Check out the ROG article on the circuit for more info and a couple of mods.

    1. Yes, you can run pedals into it and will work fine as a low wattage amp. Not sure about the speaker ohms, but 8 is probably fine.

    1. its a 1watt amp..you should try 4ohms or 2ohms..maybe it would sound better..the smaller the resistance of a speaker the louder it gets..but also tends to distort a lot..
