Hello,
I have my Dirtbag now for almost 6months and love it.
But I hear the LFO blead trough the audio path when not playing.
Not in a high pearcing noise but more as a constand moving feedback.
An my feedback is set so i have only 4 or 5 repeats.
I'm using 4x MN3008 in my build and it's biased just fine by scope.

Could anyone surgest what to do?

Thanks for all the compliments ;)
And since you asked for it here is the gutshot:

The little pref board holds all the components for the BMP tone control.

I will do a video to, that will follow later.
I build it with 2N5474 jfet by the way.
The switches are still not wirred but the first one will change C3 between 1uf and 2.2uf (or 4.7uf)
the other one will change C11 from 1n to 10n.
I'm curious how that will turn out.

I noticed that I got the out fx and out jack wirred up wrong.
Have to change that. But because I use all my pedals in a true bypass looper I didn't noticed it  ;D

Build Reports / Chuck chuck with modded tonestack

After making the dr boogie (great PCB by the way)
I wasn't happy with the sounds. When I plugged it straight in my tube amp it sounded very trebley.
Not what i wanted, so I tried it in my effects return. That gave better results.
But for me not usable because I want all my effects before my tube amp.
So I got messing with the tone stack. What I did was adding this BMP tone control with pressence pot after Q4.
I removed Q5. It's version 2.
http://www.muzique.com/lab/tone3.htm
And added 2 LPF after this tone controle (10K/2n2) and the to the Level potentiometer.
This gave me the sound I wanted, Very nice and plesant lead tones and of course rythem tones.

The switches on the outside are not yet wirred.

Thanks for the kind words.
I'am starting to build a tape echo from scratch later this year, with part of old tape recorders.

The tape i use is Ampex tape, got it from a seller in the Netherlands.
He made the loops for me 10 for 15 euro's.

Build Reports / Dynacord echocord mini refinish

Hello,
Just refinished my Dynacord echocord mini, not really a pedal but this is my go to delay.
I sounds amazing. Got it really cheap a couple of months ago (€50,- please don't hit me)
And the heads looked fine. The was good echo straight away, but it needed some work.
I have a good place here in the netherlands who has tape loops for this device.

Here's what I did with it to make it work:
1. Cleaned the heads with some polishing paste.
2. Cleaned the rubber wheels.
3. Replaced al the Elco's in the echo.
4. Made a new back plate, the original was from cardboard and looked really dull.
5. Mad the front red  ;D

And now for some pictures:

Now a friend here in my home town etched this one for me.
Good luck with the small clone.

Thought of doing that but ended up not needing it. ;)

The Build wasn't that hard for me.
The Intense mod and the vibrato mod are on the tonepad document,
and i found the deep mod (cap change in the LFO) in a mod book from Brain Wampler.

To change the layout to the MN3207 was a little difficult.
I will draw a schematic how I did this.

By the way, I know that the MN3207 can run on a max voltage of 10V but I did a test yesterday
where I fed 12V in the circuit and still got great chorus. Anybody knows why?
Just asking if anyone has had this to?

Thanks.
I believe they call it a 1590C.

Build Reports / Tonepad CE-2 build with mods
July 25, 2012, 10:47:46 AM
Hi,
I have made a CE-2 clone on the Tonepad layout.
Since i had a set of unused MN3207 and MN3102 I put them in here.
I made some changes for powering the MN3207 and worked great.

I also like the looks of Toneczar pedals so that was my inspiration for this one.

Other mods I did was:
- Wet level pot
- Vibrato switch
- Intensatie switch (ads a 100pf in parrallel with the 47pf cap add the MN3102)
- Deep switch (changes the 0.1uf in the LFO section to a 0.068uf)
- expression pedal input for the Speed pot, (haven't tried this one out still)

Here are the results. (The guts are a little messy, a lot of wiring)
