This bass is currently being built by Jimmy Coppolo. Sunburst professor finish. This is the Holy Grail of Jazz basses. This is an attempt to produce an exact replica of a 60's bass with Alleva-Coppolo's pre-amp design and a powerful low B string. Coming mid-September 2020, for our friend on the West Coast, Christian.
