how can I record my guitar to sound like a bass in garageband

This may not be the place to ask this but I will anyway

I once saw a youtube on how to set up Garageband to record my acoustic guitar and have it sound like a bass.

I have a song but I don't have a bass

I plugged my guitar in and selected the bass patches, and tried to get it deep down, and then when I changed bass patches looking for a 'passer' sound, I was asked to save that setting—there's a question for another post...

Has anyone had the need to record their acoustic guitar to sound down like a bass and found a way to do it.

PS, don't know a bassist to borrow one from, I've already been suggested that, lol
