Envelope Filter (MXR Clone)

If you want funk, play funk. This pedal will definitely help you on the road to sound like Bootsy Collins or George Clintons Parliament-Funkadelic. Although it has a little distorted high end it has a really cool sound to it and it is hard not to get funky as soon as you stomp on the ON button. The bother button is a reversed TOY sound insted of a Wha witch gives it an even wider range of varied possibilities. I also made one to a friend of mine. In that I added the filter range mod after fiddeling with different caps. It really payd off so I recomend you to add this mod.

!Caution! All manufactures of IC for this one does not work. Be aware and read the build reports on Tonepad

QUACK (Nurce Quacky)

This one does the same as the MXR Envelope Filter but lacks the "Toy" button. It is a much simpler circuit. When I tested it I thought that the high pitch was to pronaunced and a bit distorted so I added a on-off-on switch to change the filtering range. The left position addes a 10nF cap in paralell to each of the 4,7nF filter caps. The right position adds 22nFcaps and the middle position is stock. This way I can get a bassier sound without the real high pitch. If you have limited experiens of building effects I recommend this in to the MXR because the easy build and the small difference in sound. Alltough the MXR is more tweakable and versitale.

Good Vibes (Univibe clone)

Some effects has a mystical vibe to there name and stand out as the reincarnation of the late 60:s. The Fuzz Face is one of them and the Univibe is another. The Fuzz Face is an easy build, as soon as you have got youre hands on the right mojo Ge transistors that is, the univibe has much more to it. The original circuitry is fairly advanced. The mojo here is all around combination of 4 LDR:s and one light bulb in a sealed compartment. Get the right light bulb or you have failed according to Fulltone (I really doubt this). This circuitry solves this issue with 4 LED:s coupled to the LDR:s and an OP-amps instead of all transistors. Geniusly done and with the same cind of sound result. You can actualy dial in the MXR 45 sound on this one. Allso check out R.G:s ramp up /down speed to slowly change between two preeset speeds. Really cool mod. It is also usable for other LDR/LED based LFO circuts.

Captain America (MXR Phase 90)

This is the Tonepad version of the MXR Phase 90 original below. Its 90% true to the original in sound but lacks a little bit of ssswoschhhh in the middle. As you can see on the inside picture I made the depth mod but mounted the pot inside. I wanted a clean one knob design. The switch is for the script mod. (omit the 22K feedback resistor). The LED is a read and bright and the anode side is connected to the speed pot lug-1 witch means that its flashing at LFO speed.

MXR Phase 90

This is one of four commercial effects that I own and have decided to keep even tough I have have built a clone. Soundvise my clone comes really close but lacks the final touch. I have done the script mod; on this one and it sounds great.

MXR Phase 45

This is the 90:s little sister. But I would like to upgrade this one to THE ONE to use. It has a marvelous swirling sound in just the right proportions. And this one is a genuine script model from early 70:s. (people I trust say that it is from 74). I bought this dead cheap on the net. It already had two holes from an earlier attempt to add external power to it. I added a yellow dim LED, true bypass and a 9V in jack. Most collectors would probably faint when they hear this but I do not collect those effects. I use them. This is the "Dark Side Of The Moon" sound in a box. Se my shrinked copy of this one as well. really cool in my upinion.
