Tools, Tones and Toys for Guitarists
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
With 1000 verified layouts in site, I figured I’d throw in something small, simple, and usable. From the Source: The Signal Pad is a passive attenuator that allows you to instantly switch to a different preset volume. It’s like your guitar’s volume knob, with a fully-passive and color-free circuit. Leave your amp’s volume set high … Read more
Very little info around on this late 70’s / early 80’s unit. Check the FSB thread for details. I snatched the image off from fxdb… Now. What’s this all about.. The way i see it, we have a buffered OD250/Dist+ gain stage (including clipping diodes shunt to ground), followed by a sort-of active BMP tone … Read more
Since I posted layouts for the Hornby Skewes Zonk Machine, version 1 and 2, Will Kenworthy posted links to 2 other schematics that were traced and posted over at the DAM forum for a version of the Zonk II under the Sola Sound name back in the 60’s. I figured why not make layouts for … Read more
The Zonk Machine II was the more budget friendly version of the Zonk Machine. It was a simplified circuit and featured silicon transistors in place of germanium. Originals used 2N4061 PNP silicons, but other could be used. Because it’s silicon based, it shouldn’t be too hard to make the swap to NPNs so it can … Read more
From the Source: The Lehle Sunday Driver SW is a compact-format high-end preamp for all types of electrical and acoustic instruments – a preamp that enables electric guitars and basses, acoustic guitars, and also other stringed instruments (such as violins, cellos and double basses) to realize all of their musical potential. The switchable version expands … Read more
Best info I could find on this creamy classic fuzz goodie. The 1967 John Hornby Skewes Zonk Machine II is an extremely rare, and vintage pedal enthusiasts have long coveted both the original Zonk and its successor, the Zonk II. The Zonk II was the result of a re-engineered Zonk Machine I, which was based … Read more
Description for this outide-the-box-thinking fuzz circuit is up at freestompboxes with the original schematic. Seems rather nice.
The Hornby Skewes Shatterbox is another stupid rare fuzz/booster made in the 60’s, need I really say any more? In case I do, info is not really available on this monster, but here’s what I found: Skewes Shatterbox Produced in Leeds circa 1966, the unit combines two effects; The JHS Zonk fuzz and a Treble Booster circuit, the original … Read more
Got a request to do this one again but with board mounted pots. If you don’t know, it’s a FET emulation of the classic Supro 16T amp. More info, schematic and demos can be found on the Run Off Groove article.
