A collection of Electric mandolins. We have a couple of solid body 4 string instruments, but most of these are actually acoustic/electric such as the Eastman mandolins with pickups. As a general rule, the better mandolins do not have on-board preamps. Mandolins with passive pickups perform best with an outboard preamp, but can be used straight into an amp of mixer. With the exception of a couple models that have an XLR jack, most will use a standard 1/4" cable to plug in. Models that we sell are below the Advertisement.
