Tools, Tones and Toys for Guitarists
Info from Runoffgroove about the project: Around 1965, Marshall introduced a few amps built around an 18 Watt EL84 powered circuit. While these models were intended for practice, the sound was much better than other small amps. Unfortunately, only a few hundred of these combos were manufactured over the next three years. These rare amps … Read more
Requested by a few people, this is the pre-amp section of the rack mounted Korg SDD-3000 digital delay. One for the U2 fans who want to try to get a bit closer to The Edge’s tone. This one based on Analogguru’s schematic with a simplified 9V supply.
Info from Boss: The OD-1 is by now legendary. Artist of the 70’s was mostly using a fuzz distortion sound and the overdrive produced by the OD-1 was not typical. It was however soon accepted as the new standard of guitar sound. The OD-1 features an asymmetric circuit where the positive and negative halves of … Read more
Very similar to the Drive Master posted a couple of days ago, but thought I’d include the full layout to keep things complete. This version with a diode/LED switch as per a request I had. If you’d prefer yours to be like the original and have fixed LEDs rather than this switch, then just solder … Read more
From an 80s Marshall ad: Fire your cartage company. You don’t need a rack full of gear to get distortion that goes from subtle to stun gun. If you want all the range of a top studio pro, the Drive Master is for you.
Should be pretty obvious what this one is based on but people rave about it and it does have subtle differences in the schematic, not least of which the clipping switch, that will make this one a worthwhile build. I’m not sure if this is the official John Landgraff’s description of the pedal, but it … Read more
A few people have asked for this so thought I’d add it. If you want to include the loop it’s a pretty simple affair. Volume 2 goes to the tip of a switched socket (Send), and the normally closed contact from the tip goes to the main stomp switch board output lug, and also the … Read more
Something for you all (especially Miro!) to do with your low gain germaniums that you thought were going in the bin. Info from mictester about his circuit: I’ve got back to the work bench recently, and found that I had a lot of germanium diodes and transistors. Most of the transistors were very low gain … Read more
This is a great sounding effect by Dave Barber, modified to put the Sub Bass pot external. Dave sells effects at great prices and their build quality is second to none, so this is one of those builders that everyone should support where possible. So if you get an opportunity to buy any of his … Read more
Requested by a few people. Horrible to do a layout for because of multiple cascading stages with close connections from a 14 pin IC which means you can quickly run out of space, but managed to work my way through it eventually. At 22 columns wide it will just fit in a 1590B if you … Read more
