Adding feedback diodes to the LM386

hey guys!
I was thinking... Looking at the rough schematics of the chip, you can clearly a feedback loop, which can be altered with pins 1 and 8, or even with 8 and 5 (bypassing the resistor). What if you add back to back diodes (think zeners) between 8 and 5? These should be chosen just under the clipping treshold (I guess around +/-4V when using 9V power). Wouldn't that improve the overdrive character?

i have been thinking along similar lines about adding clipping into  a fetzer ruby. i wouls suggest having a look at a schem for a rambler like the one here http://www.geocities.com/tpe123/folkurban/fuzz/snippets ill prob tinker a bit this weekend, ill let you know how i go :)
