I'd also point out that a higher string action will make your instrument project better and also let you dig in more.
Of course, you might have a high action already...
I'm sure the riser will help.
When I got my first bass guitar, I haven't had an amp for a while.
Practicing, sitting on my bed, I've noticed that the bass was amplified by the one-piece headboard that I pushed the bass' body onto by accident.
I played in that spot all the time. 🙂
