Morecowbell, thanks for those great links you posted, but if they are all avaible from one location, it's better to just post that one link. If people are interested in discussion about this or that box, that can become a separate thread.

They are all in the $59-159 price range! Anybody has more info on this brand, we're still waiting for the english version of the website..

I just found this old article from Electronics Today International, this is for a Fuzz stompbox which gives three sounds, Sustain, Fuzz with Sustain, and Fuzz without Sustain, looks like an interesting design which doesn't follow all the usual commercial designs, so I though I would post it here in the Davidoff library for anyone interested, enjoy.... :thumbsup

Full article in PDF: : Elektuur 54 1967-6 Guitar built in fx.pdf

Here's an article from the Dutch magazine Elektuur, which is the precursor of Elektor, in which they propose a new electric guitar, the ALL-GITAR. In fact, it's just a active effects circuit built into the guitar: fuzz, frequency doubler, tremolo?

The same issue also contains a nice little EL84 pushpull amp for people who like old stuff. The article from 1967 starts out: In this era...
