Re: Wampler Pantheon [traced]

I have checked the vero layout now and even built it after this layout and it works very well.
So this layout is verified.
One thing, if you want to Power this with 18V, then all electrolytic capacitors must have a rating of at least 25V.

Re: Wampler Pantheon [traced]

Hello All!

I have breadboard tested the schematics now and it works.
I also have made a vero layout and now I have built it after my layout.
I will check the layout so everything is ok, then I will post it.

Re: Wampler Pantheon [traced]

Hello! First I tested with 10n in C13, to see how it worked, then I found that what you wrote, that 330pF works the best. So FeVeR2112, if you could only measure C13, without solder it out of the board, to what the measurement will read. I have also started with a vero layout of this pedal using the...

Re: Wampler Pantheon [traced]

Hello All! Thank you all for superb work! I have started to breadboard this to see if everything works. I found this on the web. https://www.diystompboxes.com/smfforum/index.php?topic=96844.0 In this you can see that C11 will be 470pF. I have a question regarding C13, can someone that have this peda...

Re: Caline Mark 4 [schematic]

I have found a error in the schematic.
The diode labled D5 that is in the power line, should be labled D6 and it's a 1N4007.

Re: Caline Mark 4 [schematic]

Hello Everyone! I have discovered that this pedal is a gem, because if I put this pedal before my homemade Mesa Bbogie Mark IV pedal (I built this about 4 years ago), then the pedal gives a good crunch in the Mark V pedal. The Caline Mark 4 is a very simple circuit, but it sounds very good. You can ...

Re: Caline Mark 4 [schematic]

Hello Everyone! Here comes the schematic of the Caline Mark 4 Distortion. I have tested this schematic on a breadboard and compare it to the real pedal and both sounds almost the same. I have also tried some different IC's, OPA 2134, OPA 2604, RC 4558P, JRC 4580, NE 5532 and LM 833. All of them soun...

Caline Mark 4 [schematic]

Hello Everyone!

I got the Caline Mark 4 today and has started to trace this pedal.
After when it's finished, I will post the schematic here.

Kitty Hawk Quattro Preamp

Hello! I have made a vero layout of the Kitty Hawk Quattro Preamp, only for Lead channel. I have also put a switch that bypasses the 2nd gain stage, so you can choose between Lead or Hell mode. After this layout I have built a vero board and it's tested and working. kitty hawk quattro preamp 1.pdf E...

Hello! Since I never got the Layout Creator software to work, have I done a layout in a CAD program. I have also made a layout for the switcing channels and Power switching. You can take out the 220n cap between Q4 (D) and the tonestack and replace it with a link. I have changed some values for the ...

Hello! I have built a Splawn Nitro in a pedal now and are tweaking it so it sounds good. I also experimeting with different overdrives, distortion that will distort this pedal even more, acts as channel 2. The ones that I have best result yet, is MXR Distortion + and Ibanez Jet Driver. I hope that I...

Re: Suhr - Riot [traced]

Hello All! I have built this pedal for a couple of years ago, it sounded very close to the original. I think it was last year I found a new schematic and this was changed with 51v zener diodes for the clipping stage and some other cap values. I made a vero layout after the new schematic and what I d...

Re: Wampler - Tweed '57 [traced]

Hello Everyone!

I really like the sound of this pedal. I will build this and I have one question.
In the vero layout is a switch, but it is a on/off/on or a on/on/on?

Re: Wampler Ecstasy

I have built a Wampler Ecstasy clone and my pedal sounds like the real thing.
It's strange that you get fuzz sound in your pedal.
Which IC do you have in your pedal?

Re: Hotmod 800

Hello All!

I haven't done anything yet to build this pedal, but I have search on the web and found a schematic of a Landry amp.
I am working on this with JFETs and MOSFETs to see which will be best, so the sound will be the best.
I will come back when I have more info of the progress.

I have also trying to found schematic of this pedal, but still haven't found any. I have listen to this pedal several time and I think this is based on a Marshall tube amp of some kind with replaced eq to an active one instead of a normal marshall tone stack. This could also be a modded circuit simi...

Heloo Mboratto! I used the same values, but not R14 and the capacitor on the power line, I used a 100uF. I replaced the resistors to the plates of the tubes with variable resistors, this is for that you can adjust the voltage of the drains of the transistors, start to adjust the voltage with the hal...
