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.

EWS Little Brute Drive

Found this one on FSB and haven't seen any layouts for it, so I thought I'd give it a go. Originals are in 1590A enclosures with the Tone and Volume controls as trimmers, but I've laid them out as external controls. There seems to be some discrepancy on the taper of the gain control in the schematic, unless EWS uses a dual-gang pot with different tapers. I'd just go with a linear taper and hope for the best. Should fit just fine in a 1590B with board mounted pots.
