  • CGS 29 Wave Multiplier Panel

    Some years ago I bought some PCB for various synthesizer modules. I thought I would design some panels and build a few new modules. This is a first draft of a panel for Ken Stone’s Wave Multiplier CGS29. I have the first version. http://www.cgs.synth.net/modules/cgs29_wave_multiplier_v1.html  

  • Millenium Bypass – Working!

    Millenium problesm all solved with the help of R.G. Who kindly pointed out that I probably didn’t have a path to ground on the out put of the effect. Which was exactly right. After having the Millennium work so well on the SHO, I decided to add one to a Fuzz Face. This Fuzz Face…

  • Dual Booster now with LEDs!

    This has two booster in series in side. First is a NPN Range Master followed by a Sparkle Boost. The idea was Joe Gore’s. The two booster work well together. They each have their own flavor, and together get a good over driven sound. The Range Master side sports a variable input cap. So this…

  • Millenium Bypass, not so fast

    I built this last week, see the previous post. Everything seemed fine on the bench. Today I gave it a test with the band. Seems like it is not working quite right. The LED lights when the effect is on. But, when the effect is off the light slowly turns on over a few minutes.…

  • Millenium Bypass

    This is one of those things that has been around for a long time. Back in the olden days when the 3PDT switch was hard to get and cost as much as all of the other parts that went into a box. There was a need for a status LED that could be operated from…

  • Mold Spore Psycho-Scumatic Wah and Ring Modulator

    Mold Spore Psycho-Scumatic Wah and Ring Modulator

    Sounds like something from an old Bugs Bunny cartoon. Though it might have appeared in a Warner Bros. production it could have easily added to a sound track. Looks like it should be on the floor of your custom van, the one with custom paint and interior. This is the Snarling Dogs Mold Spore Psycho-Scumatic wah. We’ll…

  • Eagle PCB – Autorouter

    Obviously it would be great if a schematic would lay itself out. Eagle and other applications have included Autorouters, that do just this, for years. In the case of Eagle this was a feature you had to pay for. Until recently, well recently in years. Of course the computer in this case can not do…

  • Box of MOSFET

    Rock Box! I was talking to a friend about distortion boxes and the Box of Rock came up. Which got me thinking, I’d never heard one before, and Z Vex always makes good stuff. I found a schematic in the usual place. It looked like a pretty easy build. The Box is basically two pedals…

  • Meatsphere?

    The Meatsphere I hate that name. Then again it’s a play on the name Meatball. The Meatball, if you are not familiar, is an envelope filter based on the Mutron III. The Meatball was made by Lovetone who went out of business in the early to mid 2000s. Lovetone seems to be coming back. Hard…

  • Ugly face with tone control

    The Ugly Face has an interesting set of options. The Threshold knob has to be the most interesting though least useful. Last year I thought I’d add a tone control in it’s place. I wanted to build an Ugly Face and keep it in 1590B sized box. This format makes it hard to fit more…

  • Fender Vibrato/Tremolo

    I had just read an article on Fender tremolos here. This article brought up the subject of the Fender three tube Vibrato/Tremolo. This is a tremolo effect that pans between two signals, one from a High pass and the other from a low pass. The sound while not truly tremolo and not really vibrato has…

  • True Bypass with an LED!

    I bought this switch from Smallbear about ten years ago, probably around 2000. It cost $13! Before that time this was a high tech item that was only available in Fulltone products from what I understand. Legend has it that he had them designed and specially manufactured for his boxes. I guess wiring a true…
