Srtring tension

Effort in what part of play? Fretting notes or fingering/strumming?

 

It could depend on the string gauge then. Or the type of string. Are you using light or extra light strings on the electric? As for the playing part, the piezo in the ABG could be quieter than a regular P pup, making you pluck harder to get volume.

 

Acoustic Bass Guitars are usually set up with much higher action than electric basses. The strings are higher up off the fingerboard. It hurts more pushing them down. It's not extra tension, although it may feel like it.

Lower priced ABG's in stores can be particularly painful to play. They can be set up with lower action to make them more comfortable, if you like. But they are normally set up high so they can be plucked hard to play loud.

 

It is just you.

If they're the same scale length and you put the same strings on them and tune them to the same notes they will have exactly the same string tension. Because science.

If you put thicker strings on one then it'll have more string tension.

 

Fretting effort and plucking effort are not determined by 'ABG versus electric bass', but by string tension (determined primarily by gauge), string stiffness (which is different to tension, and is determined by string type and construction) and string height (which is not easily adjustable on an ABG and is usually quite high on an ABG).
Bruce Johnson is correct.
