PostPosted: Tue Nov 06, 2018 12:35 pm    Post subject: 4069 Overdrive Reply with quote  Mark this post and the followings unread

In a local musician facebook group, someone was asking about a good option for a stereo overdrive effect to use with his keyboards and synths. He wanted stereo specifically for a piano patch that he says doesn't sound as good in mono. A lot of people chimed in saying that they would like a good stereo overdrive too, and had just been using dual guitar pedals.

So I built this one and post it for sale in the group. If it sells, then I might do a few more. I built it into a metal watch box. I have three more of the boxes.

It is just a CMOS 4069 wired up like an opamp with variable gain. I also added a 6dB low pass filter for tone control. There is also a volume pot to keep things under control when driving it hard. I also added a bypass switch.

Nice work on the case ! Everything fits well. Nice mix of modules in there as well. Went over to your blog and took a listen to your music. The piece called setting 2, is this from the modular your showing off today? Like the sounds !

One APC + CV finalized and another APC with an integrated 8 step sequencer in the making...
Can't wait to move on to more exciting stuff, like MFOS .

congrats on your build wavejumper ,there are many simple circuits you can build and still use them in standard modular ,just a thought .. the first thing i built that worked was lfo from the wildcat http://www.modular.fonik.de/files/EFMforum/orgEFMfiles/wildcat_001.pdf ,then at some point i made this sample and hold http://www5b.biglobe.ne.jp/~houshu/synth/ShMos0212.GIF which is so simple but working fine as i recall ,good luck in your journey in synth diy

my second "eurorack" module, renes´s noise source,
not a deadbug, not pad'n'island, its "dead gabba's long island strip style" geek

ive made the open collector from the transistor available as an input, dunno if it makes sense, time will tell

values adapted to what i had laying around on the workbench from desoldered try'n'fails, only "new" part is a BC637 as noise transistor, which is an original Siemens with ink print, accidently found in the holy Segor-Shop in Berlin back in the days

Shocked
I'd like to see something like a klee sequencer in dead-gabba's-long-island-strip-style™. Laughing

yeah,
you know in the eastern (dark) part of germany, copper was very short of supply, aluminium was often used instead, so "they" decided to produce chips that run directly off 220V to save the copper for the transformer, they where called TL082SED220 from ROBOTRON.
I received some of them as participant of the "7. electronic youth gathering Teddy Thälmann"


i dont know if the fun-factor-while-building stays as high as it is with simple circuits if you start to build something rather complex like the klee, but never-say-no Cool - and since my own circuits tending to be dumbassly simple, i could get away with this style Smile and maybe i even get better over the time, so its not to hard to look at it anymore Shocked
