Oberheim - VCF-200 pedal (sample & hold - filter)
One of my favourite pedals..mine died in the 70's and I couldn't find a tech in Sydney that could fix it
None of the digital simulations quite have the same analog 'thwack' as the originals
(listen to Zappa's solo on 'Ship Ahoy' for a good demonstration)
Anyway..I couldn't find one on the forum which I thought was a glaring omission
If someone has copied this, I'd like to know about it

Cheers, squatch

squatch, I'm working on a clone, I design my own PCB for it, and it is in the prototype fase at the moment.
It is working just the way it should ( I had an original Oberheim my self, sold it last year). the sound of the thing is very dependable on the transistor used for noise generation, so you have to sort a lot of them.
Here a picture how it looks now:
Maybe I will sell these in the near future, I fist have to find good sourcing for all parts and a nice design for the housing.
Cheers Peter

What are the differences between this one and the FSH1 from Maestro (which was built by Oberheim anyway)?squatch wrote: If someone has copied this, I'd like to know about it
Is it based on a CA3080 too?
The only difference is the housing, both uses the same board. And yes they are based on the 3080.Zokk wrote:What are the differences between this one and the FSH1 from Maestro (which was built by Oberheim anyway)?squatch wrote: If someone has copied this, I'd like to know about it

Thanks for confirmation pdhoed.
So squatch, you should have a look at the tonepad page... their clone uses the LM13600/LM13700... and I think it's even possible to use a NE5517 as it's compatible pin to pin...easy to source and a lot cheaper than the 3080!

Hey thanks Peter & Zokk!
BTW I'm just a guitar tech that can solder so I wouldn't attempt a build
But my synth tech could build one (if I don't get one from Pete...heh)
Thanks again guys

The noise source is absolutely key in determining the frequency range and "randomness" of the filter. A really noisy 2n2222 for example tends to get locked on certain frequencies which gives the pedal a really unique electronica sound. Something more even gives the classic pulse. Buffering the front end is an easy way to kill off any tick.

Tonepad has made an exellent board available for us DIY'ers see my comments on the project here: https://www.freestompboxes.org/viewtopic ... 19&t=16673squatch wrote:If someone has copied this, I'd like to know about it
