How did the Entwistle Flying Fake sound? From my experience (I have seven Flying V basses: 1x Kramer alu-neck medium scale, 1x Ibanez long scale, 2x Gibson short scale, 2x Dean long and extra-long sale and 1x the remarkable Dutch Brooks brand, long scale), getting a Flying V bass to sound well and authoritative is a task, especially as a short scale. Something about the - visually appealing - Flying V shape doesn't work all that well with bass. A massive neck helps.
