FuzzPup Pink Plexi

This is part of our FuzzPup range of circuits designed for 1590A builds. Please read the general build doc available here and ensure you're happy with what's involved. They're not especially difficult, but working in a confined space can be fiddly. Take heed.

Of course there's nothing stopping you using these PCBs for 'standard' builds. They're Direct Connect compatible.

Clone of a famous purple Marshall-in-a-Box pedal. Dial up some crazy high-gain crank in a very small package.

Volume control does what it says, Frequency offers a good range of filtering to tune the tone just-so. The Gain control seems a bit of an afterthought on the original, but we've swapped out the linear pot for a reverse log which gives much better control. This is pretty full-on no matter where the gain is set though.

Warning - this is not a quiet circuit. Some noise may be present if playing gently or with the guitar volume wound back. 'Tis the nature of the beast. Who's going to play this quietly though? This is hard-rock/metal through and through.

It's a tight squeeze with three pots in there, but we've taken some of the hard work out of it for you. An optional daughterboard mounts the three pots straight to a PCB, which can be connected to the main board with a short length of 9-way ribbon cable. This will need to be cut and stripped, which is a little fiddly, but will result in a neater build than all those wires cluttering the place. See the pics to the left. Neat huh?

Partial kit: PCB, all board-mounted components, pots.

Not at all Perplexing 4 product stars
"The board is easy to build and, to my ears, does exactly what the original does where my rating of four stars reflects on the Purple original rather than the quality of the Pink Plexi due to its very abrupt gain control. I didn't use the reverse log pot, which I think would help (a bit) so the transition from a fair amount of distortion to a lot happens in about two degrees of rotation of the pot. This circuit can be modded to some extent to reduce the gain and to clean up the sound a bit more at lower levels, but then you can build an OCD clone if you want that. For a classic rock sound in a box the Pink Plexi is hard to beat and despite its 'enthusiasm', it still cleans up noticeably as you back off the guitar volume. Maybe swapping out the gain pot for a rotary switch with appropriate resistors would be a good option?" Paul White - 14/08/2017
