I'm thinking about getting a cheap bass to keep in the trunk of my car and play it (more like practice) at a nearby park during my lunch hour. My "real" bass is a MM Stingray-4, but of course.... that one won't be sitting in a hot trunk anytime soon. I just saw a "Dillion VMB400" bass which resembles my stingray a lot (which is good because it will feel very similar to my bass) at a local used music store, so I was thinking about getting that as my trunk beater bass. Anyway, is there such thing as a portable amp (tiny one) that maybe plugs into a cigarette lighter? Also, this Dillion bass has a finished Maple Neck. Do you guys think that will resist 100 degree trunk temps in the summer?
