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.

Wampler Paisley Drive

Got a request for this one. Another take on the classic Tube Screamer built for Brad Paisley. The traditional input/output buffers have been swapped out for JFET-based buffers, and there are two toggles for Presence and EQ (mids). Should be able to squeeze it into a 1590B.


  1. Just a heads up: I built one of these up on stripboard, and although there is buffering within the circuit, I had to run a separate buffer pre-input to prevent oscillation at certain setting. I didn't try running shielded in/output wiring, so that could be another potential fix for that. Just something to consider when planning your enclosure. Sounds great though!

  2. That is what i had been waiting for. Thanks.

  3. This one works and sounds great...Had to use Lug 2 of the Volume pot for output instead of Lug 3 for some reason, though.

  4. hi
    first sorry for my english i am from austria!
    one question: the 511Kohm resistor is for biasing the j102 ?
    and can i replace the two 511k resistors with trimmers?
    maby iś easier to adjust the voltage.( about 4.5V right? )

    greetings from austria

  5. i forgot, has anybody build an MXR micro Chorus (3007 version) ?
    im looking for a pcb,and parts layout.
    i found one unverified project but itś hard to read,
    if anyone has informations please let me know!
