Hi guys,
I'm looking to reduce the maximum Depth this circuit will acheive and also to smooth it out a bit.
Any ideas?
I upped the value of the electros in the LFO section but would like to decrease the depth.
Any advice is appreciated.
Here's the schem;

Thanks!

Sorry, To see the schem you'll have to cut and paste the link.

Here's alook at the schem.....

Perhaps a modification to the way the depth control is hooked up in the circuit could improve the performance. 
Please let me know any ideas you may have!
Thanks

Try reducing the amplitude pot rating, 22k should be low enough to reduce the maximum depth.

Thanks Zero.
Great Site BTW! 
I had messed around with pot values a bit but, it still didn't seem to be as smooth.
I'm looking to making it a bit more subtle, I thought perhaps a resistor tied into the pot or perhaps inline to the BC170 base.....the one  with the 50k to it.
