zVex’s new ’59 Sound looks to emulate an overdrive ’59 Fender Bassman amp and is essentially a tweaked Box of Rock. I’ve left out the boost section (which is essentially a SHO after this circuit), but can be easily added with the old SHO layout here on the blog. Also, there’s another installment of the … Read more
Original FSB thread and schematic available here. Special thanks to Bugg for providing new schematics.
Tweaked Mark’s original compact layout according to the info i found on the fat mode switch. Should be good to go.
This is a pretty handy expansion of the zVex SHO booster. It stacks two SHOs together and adds a master volume control. This is laid out so the board is vertical in a 1590B oriented like the original.
For Fuzz Friday, here’s a layout for the Fat Fuzz Factory in a 1590B in a more traditional orientation. All pots are board mounted as well as the Fat Switch. For C1 and C2 you’ll probably want to experiment with values. Using an on/off/on switch gives you an extra option over the original. 3.3uF is … Read more
This cool sounding fuzz was traced by our very own Ciaran Haslett in the forum. Check the forum for Ciaran’s schematic, info, and layout (which is one column smaller than mine). I noticed Ciaran requested that this be redrawn for the main site, here you go 🙂
Happy #fuzzfriday, everybody. The Mastotron is a heavy silicon fuzz and a variation of the Wooly Mammoth. It can produce a wide sonic range from 8-bit sounds to complete wall-of-fuzz tones. I’ve drawn this up to fit in a 1590B more conventionally than the Zvex way. You can use PCB-mount right angle pots, mounted from … Read more
The Fuzzolo is one of the newer Zvex designs in a 1590a box. It’s a stripped down Woolly Mammoth with a SHO added to the end, so it’s got a huge fuzz sound. In production versions, there’s a moveable jumper internally to go between active and passive pickups. You could use a SPDT switch to … Read more
Looking for a Wooly Mammoth but don’t want a sideways 1590b on your pedalboard? Here’s the Zvex bass fuzz laid out for board-mounted right angle PCB pots.
This layout is for the distortion side of the Box of Rock. The Boost side is just a SHO. I’ve laid this effect out for top mounted pots like in my other Zvex layouts and should fit vertically in a 1590B. Pots are 1.1 inches (28mm) apart. Board dimensions: 3.2 x 1 in. or 81.3 … Read more
