Any issues with two LFO circuits sharing power?

[lincolnic]

This might be kind of a dumb question, but I'm gonna ask it anyway. I'm in the planning stages of a 2-in-1 build, with each circuit having an LFO (in this case, the Machette and Arcadiator). I know sometimes you can run into heterodyning issues when you have two different circuits with clock chips sharing the same power, but is there any kind of similar issue with two different LFOs?

I don't think there is, as I see tremolo and phaser combos pretty frequently, but maybe there's something else I need to learn.

I've built couple modulation combos, 2 or 3 LFO in the same box, never had any issues, always mix matches of Phaser, BBD, trems..  but everytime i tried matching 2 BBD effects i was getting ticking.

What helps is to keep the grounds and power lines separate and tied only to one point (at the power jack for example)
If both circuits have power filtering it should work, but you never know until you try :-)

Makes sense to me. Thanks, guys!

Here's a thread I just read yesterday: http://www.freestompboxes.org/viewtopic.php?f=49&t=1392

I'd try the rail decoupling: it's only couple components and very easy.

I'd agree with that, though.... if you take look at the schematic of the effects you want to match together, chances are that it will already have a low value resistor tied to the V+ Source, followed by a filter cap that will in most case be a 47uf or 100uf, Bump up that value and you're good to go, if you run into an issue that is...

Thanks guys! I'll check the schematics and see if I need to add any additional decoupling once I get around to this project.
