i guess so....

TL072 are better for low input signals... like for microcphones.

kung mahirapan ka, try to find LM358... very common yan sa local stores. another thing, it could be powered with single supply (not split type)

yung half lang ng circuit ang gagamitin mo syempre kung mono lang naman ang gagawin mo.
