:hmmm: what can we say about this pedal ?
We have japanese jacks and footswitches used in the 70´s. A TI 741 from 1979.
Radiohm potentiometers from the 80´s cause later they didn´t use this brown pertinax.
two Siemens MKT film caps late 70´s or early 80´s.
One Philips electrolytic, Piher and probably Vitrohm resistors. Germanium AA119 diodes. The holes for the components are 1mm.

That means:
This unit neither has been made in US nor in Japan. It has been made in a small business (1mm holes instead of 0,8mm) most probably in england in the early 80´s.

There´s a sucker born every minute - and too many of them end up in the bootweak pedal biz.

Great box, I love the footprint, very cool. How does it sound?
The Freestompboxes Forum search function is soo great, use the search function..., the S E A R C H function.

Woah, 10K input impedance...
Maybe an input buffer would help it to sound less boring?
Interesting to see switchable diodes on an old thing like this.

And you STILL have it???? :p

I think I saw a D&M pedal before (on Marktplaats?), but it's not on my site, so I have to search my archives...

If it's really a brand and not DIY I should add it to my site...
