Tools, Tones and Toys for Guitarists
I do find these small boards less stressful to draw 🙂 This one is small enough to fit in 1590A without any problems, but if you’re feeling adventurous you can shave off one row from the right hand side. I left there a bit space so 100µ caps have more room to sit in nicely… … Read more
This was my take on the DBA Robot but with individual switching for the IC internal functions (Vibrato, Robot and any of the octave options on the fly) rather than the rotary switch used in the original. I thought it would be more versatile to be able to control them all individually rather than be … Read more
So. It’s April already. This one is the last post from me for today. I do believe there lots of you who have been waiting to get your hands on a doable octave down circuit. Here it is. You should probably try this with a fuzz in front of it 🙂 Edit! Here’s a link … Read more
Small and simple. Tim Escobedo’s adaptation of Interfax Harmonic percolator. This demo vid is not necessarily 1:1 with the schematic, but it should give you an idea what to expect…
There was a mistake on the layout, that’s now fixed. This calls for both +9V and -9V supply. Use of inverter pump daughter board is recommended. The GEU is good sounding octave fuzz, with an optional mode of just fuzz. The fuzz is a fully rectified signal and is quite chewy. For some the Fuzz … Read more
Gus Smalley’s “Octave Up Sick Box”. And demonstative video from one cool dude who’s been around the blog sometimes too. He also has a few words of wisdom to share! Check it out! Built it using 1N60Ps for D1&D2, 1N4148s for D3-D6. Works like a charm. Well. A sick charm, but still 🙂 And here’s … Read more
This one is definitely verified, but: The LFO section is *very* sensitive to both voltage and current, so if your board doesn’t fire up right away (which happened with my second build too), you should consider doing a little daughterboard with 9V regulator, 8V2 zener and a 10-50 trimmer to get the LFO going. That … Read more
When i started to draw layouts, i did draw something like 10 of vintage fuzzes that weren’t published on this blog earlier. I build most of them and that’s when i realized why they weren’t posted. Most of them are pure crap. For those who are after “that 60’s sound” – the ear piercing super … Read more
Yay, our 100th fuzz pedal layout! And yes Vince, I know you’re going to be annoyed about one of the pots! :o) I left the power supply filter / smoothing cap optional because we know from previous experience that they can change the character of the fuzz and tame things down a bit, so I’d … Read more
