Hitting myself

i was so fixed on this one problem that i overlooked something as simple as the input pot and it's value.....

simulated it with a circuitprogram and it turns out you can set ratios to the input voltage!! how could i've been so stupid to completely overlook this????

well i got my answer now!!

.....reducing gain with feedback looks interesting but really i should be able to get it working without before i will be able to use nfb..i just don't know how to use/implement it....
