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.

Rockett 10 Ton Hammer

This appears to be Rockett's take on the Marshall Guv'nor, but with a few modifications. The tone control of the Guv'nor has been replaced with a Baxandall EQ tone stack and the output is boosted with a JFET gain stage (much like Rockett Flex Drive). Should fit nicely in a 1590B with board mounted pots.

  3. Anyone else having troubles with this one? I built it up and when I power it up I get a hum and the light on my power supply goes dark like there is some sort of voltage inversion. I've been debugging but haven't found what the problem could be quite yet.

    1. Yup here too, built the pedal, checked the paths, voltages and it seems that it doesn't work, got no sound from it even compared the PCB to the schematic in freestompboxes forums.

    2. Ok, so it's not just me. Yeah I tired comparing it too. Can't seem to figure out what is wrong. I just breadboarded it based off the schematic and that worked. Wasn't really all that blown away with it. But I'd like to figure out what went wrong with the board.

  4. As a side note, I changed the J202 for the 2N5457 (not the best replacement, but it's supposed to work as a drop-in replacement).

    I've checked the version of this board compared to what the latest fixed schematics said (10k from bass pot to ground instead of V+/2). And it has those changes.

    Still can't figure out the issue
