Re: Wampler - Ego Compressor - Gut Shots

I guess It could looks like as: https://dl.dropboxusercontent.com/u/209400/PCBs/5K-Comp.png This is not a 100% to original, but is very close. I don't have Ego Comp pedal on my workbench. I'm just tried to design similar device to my customer. It's verified on 90%, just may be need a couple final tw...

Re: DOD - FX25 ( Envelope Filter ) [schematic]

Here is sound https://dl.dropboxusercontent.com/u/209400/piod/dodfx25.mp3 And my tweaked layout for bass with blend. But I have a one trifle: when we add decay knob, it's work good, but bias voltage on cap is drop down (when we tune this knob). Bias need to be 0,9v on electrolytic cap for a clean fi...

Re: Cab Simulator Design

the first part sounds pretty good (what I assume is the cab sim'ed sound), the next one is harsher(sounds like nasty solid state clipping), but doesn't seem exceedingly so (probably my ears seem to have lost a bit of top end though). Yes. You hear through cabsim for firts. Ok, your vote is good. Th...

Red Bug Distortion

Hi, everyone. Here is my small step by d.i.y stompbox building. Red Bug Distortion – is a classic hard clipping distortion pedal This is a very simple and good sounding distortion pedal. You can see a very familiar circuit. This pedal have a voltage multiplier to 15-24v for a more headroom and dynam...

Re: JHS - Angry Charlie - sound bad after change good parts

Maybe it's the placebo effect. JHS use not most badly capacitors. Сlip diodes should affect more.

Re: High, Mids, Low. How it looks on the oscilloscope?

I apologize for some of the details. I work with a distorted signal. I have the oscilloscope and a sine wave generator, my set up 440 Hz, 0.5 volts. The circuit gain gives an almost rectangular shape, and it goes to the tone-stack, that I'm looking shape. Is it possible to configure this way? I'm an...

High, Mids, Low. How it looks on the oscilloscope?

Please help me find the information. What would look a signal of "good taste" on the oscilloscope screen. I realized that the waveform should be "sexy" without any distortions. But I'm confused with the experiment. We can adjust our pedals by ear, but oscilloscope screen can give a more precise answ...

Re: RC filters! Help me understand it.

In a very simple nutshell, without going into the actual physics and maths of their behaviour, capacitors 'pass' high frequencies and resist low frequencies. It's easy to remember which way round that is, if you bear in mind that caps are open circuit to DC, which is 0Hz - so low frequencies - whic...

RC filters! Help me understand it.

Many effects are include RC filters. Help me understand it, please. http://gyazo.com/37a74f825226d8f76384dd30281257ea.png Is there area №1 its a high-pass filter? If this is true, why resistor R1 is in series with the capacitor? How to calculate cut-off frequency? http://vt-tech.eu/images/articles/c...
