ARP Odyssey Filter Mod

via here on http://www.arpodyssey.com

"Modification for the Arp 4072/4075 filter to expand frequency response.

The four 4K7 current limiting resistors which are connected between

the exponential converter and the four discrete gain stages should

be lowered to 2K2. These are the only 4K7 resistors in the module,

so locating them shouldn't be too difficult.

Another way is to add another set of 4K7s in parallel with

the existing ones. These could be mounted on the solder side of the

board. Beware of possible shorting to other pins."
