Tools, Tones and Toys for Guitarists
The XB-70 is a clone of the Captain’s personal ’77(?) Guild Foxy Lady, which were built by Electro Harmonix and generally very similar to Ram’s Head Big Muffs. In the Captain’s own words, “It sounds like torn leather soaked in piss and salt smushed lovingly into ears… It is a brute of a pedal, has a … Read more
If you’re a Dead Head, you’ll probably be interested in this one. It’s the pre-amp from Jerry Garcia’s Tiger guitar used from ’79-’89 and built by Doug Irwin. It’s a unity gain buffer to prevent signal loss with long cables. It can be built into a guitar like the original or into a 1590A. Other … Read more
We do get quite a lot of requests to post the schematics with the layouts. Please note that we can’t do that unless it’s our own work. We may link to a forum thread etc. but we cannot post other peoples work witout their permission. This is the reason for not posting schematic files. Once … Read more
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.
Fuzz Friday! Here’s a cool one designed by Alec Breslow (check him out on Instagram) who was cool enough to share his schematic. It’s based on the EQD Acapulco Gold with an added blend control and Baxandall EQ. Good for both bass and guitar. It’s laid out for board mounted pots an will fit nicely in … Read more
Here’s another take on the cascaded JFET overdrive design. This has a similar goal to the Catalinbread Sabbra Cadabra in trying to sound like Tony Iommi with a treble booster feeding a tube emulator. The Wizard is… A new distortion pedal, inspired by Tony Iommi’s guitar sound on the early Black Sabbath albums. It is … Read more
The Catalinbread Sagrado Poblano Picoso is a bass version of Jack Orman’s (AMZ) MOSFET Booster. Really the only difference between the two are a couple cap values. So if you want to build the AMZ version, sub the 470µF cap with a 100µF and the 220nF with a 100nF. Should be a pretty easy fit … Read more
So as most of you guys know when I’m studying for exams I tend to do a bunch of layouts when taking breaks to keep my sanity. So since I did a layout for the Tubeworks 903 I thought to myself if it’s basically a tube pre-amp I thought why couldn’t the tone stack be … Read more
JohnK had made a layout for the 903 awhile ago, and since I did a layout for the 901 i thought I’d see if I could make a smaller layout for the 903 to make it easier to put this in a 1590BB with plenty of room. I took his switch wiring to make it … Read more
JohnK had made a layout for the 903 awhile ago, so I thought I’d give the 901 a shot. The layout should be small enough to give you plenty of room in a 1590BB. I took his switch wiring to make it true bypass, and removed the additional LED to tell you that it’s got … Read more
