Tools, Tones and Toys for Guitarists
Here’s a great post from Bjorn of BJF effects on the Freestompboxes forum where he goes into detail on the tubescreamer circuit. The post is a few years old but if you’re interested in this sort of thing it’s a good read! http://freestompboxes.org/viewtopic.php?f=7&t=953
The Mad Professor Blueberry is a bass overdrive that is based around the BJF Honeybee circuit. Lohstah over at the freestompboxes forum decided to trace one and this is what he found; Check out the Mad Professor page for more info or have a look at this youtube video; There is a full PCB layout … Read more
I’ve decided to make a complete set of the Mad Professor designs that have been traced out. I’m a massive fan of Bjorn’s designs and always enjoy seeing all the little tricks he puts into each of his pedals. Here is the “Ruby Red Booster” traced over at freestompboxes.org; http://freestompboxes.org/viewtopic.php?f=7&t=13106 . WhiteKeyHole takes the credit for the … Read more
Here is a great project taken from freestompboxes.org – a simplified Klon Centaur, essentially the same circuit as the original minus the charge pump. Each part of the circuit has been modified to ensure it has exactly the same response as an original unit. It was designed by mictester (if you pop over to the … Read more
One requested by fx40b and including two layouts, one compact and one for DAM type axial mojo goodness! This isn’t yet verified and so if you make it successfully then please let us know.
Here are a few essential links for anyone looking to design their own effects circuits. These are just a few of the hundreds of pages that are useful and are the ones I tend to use most often. http://www.electronics2000.co.uk/calc/reactance-calculator.php – Capacitor Reactance Calculator http://www.muzique.com/lab/main.htm – Jack Orman’s brilliant Lab notes http://www.muzique.com/schem/filter.htm – RC Filter Cut-off calculator http://www.muzique.com/lab/buffers.htm – Basic … Read more
Is it a fuzz? Is it a distortion? Is it a delay? No it’s an Invading Cannibal Ladybird….. Hmmm. Here is the schematic for a crazy device I knocked up on breadboard. It’s a Cannibalization of the Parallel Universe from eaced.com, the big muff tone control and the lofi delay created by Allesz for last … Read more
Here is another Mad Professor pedal, one of the designs which has garnered the most interest around it. Well, it’s been gutted and reverse engineered. Unfortunately there is nothing new in the design – it’s a pretty standard PT2399 design based off the Rebote Delay 2.5 but it does sound very good. Here is the … Read more
I love Mad Professor and BJFe pedals, almost all of them are interesting designs and useful in a *band situation*, Bjorn does a great job designing them. The Sky Blue Overdrive has been dissected by the guys at Freestompboxes and, as per, it’s a pretty interesting design with a structure (after that standard gain stage) … Read more
Culturejam over at freestompboxes.org has ripped open the Lovepedal Superlead, guess what he found; a Marshall Guv’nor minus the tone controls 🙁 Boo. Still sounds pretty good though. Here’s the schematic he came up with; (D1 & D2 are 1n4001 type) Here’s some of the description from the Lovepedal site (apparently these pedals are only stocked … Read more
