How I Did It
Samples are used in:
Tools I Used
I used a Fender Precision bass, and played it directly into a computer without any effects or amp modelling.
Samples I Used
It is not a sample. It is a live performance.
Original Samples
Again, not a sample. I played the part.
Process
There is an audible punch-in and punch out at the bridge, maybe 55 seconds into it. A low pass filter will get rid of that.
Other Notes
It is part of an actual (instrumental) song I wrote called "Kelly By the Sea"
