Question Audio Amplifier Input Stage

Hi,

I'm designing the input stage for a power amplifier and was wondering if you pros could critique it. This is the first time I've ever designed something like this so any critisicm would be helpful! I'm aiming for something simple, cost effective and that sounds reasonably decent.

Thanks,
-=Randy Knutson

That's not an amplifier input stage. Looks more like a pre-amp to me.

I'd say it's a pre-amp as well, but I know what you meant

Some good ideas in there, but I think you may have trouble sourcing a 3-gang pot for the filter.
