My lovely wife Karen bought me a Fostex MR-8 digital 8-track recorder for my birthday!
The following recording uses the Wurlitzer sound from my Nord Electro 3, processed with its internal amp simulator, drums from my Casio WK-3000, and my Stagg EDB 3/4 electric upright bass. The drums and bass were processed via the recorder’s microphone emulation.
Wurlitzer (Nord Electro 3 73)
Electric upright bass
Maybe this will help answer the question raised earlier of what 1950s rock music might have sounded like with electric keyboards…
