As a guitarist for about forty years, I felt the desire to enjoy the deep sound of the bass and especially the double bass without great stretches of the fingers and joints, combined with a huge musical instrument which is difficult to carry/transport.
Taylor company created the GS mini-e series which is a super shortscale acoustic bass in parlor guitar size. It wears special strings that one needs to get used to. So there is a limit since you can not experiment as with a conventional acoustic or electric bass changing brands, types and different materials of strings. But this is the only compromise you have to make. This instrument produces a great sound that resembles upright bass, is extremely comfortable to play and easily portable.
I chose the version with koa wood because in various demos I watched and heard, I liked it not only aesthetically but also acoustically. If you want to enjoy GS mini properly through the pickup, you need an amplifier for acoustic (not electrical) instruments.
