Tools, Tones and Toys for Guitarists
The original used jumpers and a 4 pole internal dip switch, but I’ve done this one with external switching in mind. 3 pots and 10 toggles, who’s up for it? 🙂 Alternatively take a leaf out of the original if you want to keep the size down and use a 10 pole dip switch like … Read more
As requested. A long time ago. Size of the board tells you why it wasn’t drawn up earlier…. From ROG: More than a year ago we set out to revise and improve the Professor Tweed. Several approaches were pursued, but we were unsatisfied with the results. One of the downfalls was the high level of … Read more
Since we’re having a streak of big boards… 🙂 Guess i’m getting old too since it’s been over 15 years since this appeared on the marked.. This layout is without the input, output and switching buffers. Should still go nicely in B box. The transistors were 2SC1815GR on the original, but i’ve tweaked the layout … Read more
*Errors at the tone stack section have now been fixed…*Errors in the schematic (coupling caps at 0.068µ and not 0.68µ) have now been fixed on the layout… As requested. Paul Nelson‘s Orange Graphic MKII stomp box adaptation. I knew this one will get huge the minute i saw the schematic, but it turned out a … Read more
From manufacturer: -Heavy bottom. Rich harmonics. High tone which is not too peaky. JBK-1.0 is what all guitarists have been waiting for. In today’s music scenes, players are often required to make all kinds of sound with given amplifiers. JBK-1.0 will help you in such situations. -It covers quite wide range from soft and delicate … Read more
Request. This one comes from Harrymatic’s instructables.com project. Check out the page for more information and demo clip with keyboard. This one has really low part count, but tons of links keep the board pretty big…
The bass version was requested, so i thought i’d draw these both, as only main difference between the two is the tone stack. Demo of Geiri’s build:
And the BJT version for those who prefer them to JFETs Version without trimmers which allows you to keep the board size down:
Great circuit by Joe Davisson, but should probably be called a distortion rather than an overdrive because it is apparently quite high gain. The trimmers should make biasing the JFETs easy so don’t let inconsistent JFETs put you off. In terms of mods, Joe said of the circuit: For higher gain, change the 2.2M/100pF to … Read more
