AS Bass Collection

Every bass we have sampled in one bundle: JBass, The Upright and the four Bassysm basses, for about half the price of buying them separately.

Overview

SIX BASSES, ONE LOW END

The AS Bass Collection brings together every bass we have sampled: a Fender-style Jazz Bass, an upright double bass, and the whole Bassysm family built on a Music Man Stingray - played with the fingers, slapped, muted, and a five-string fretless. Whatever the song needs underneath it, one of these six has it.

Save about half. The collection costs less than JBass, The Upright and a single Bassysm bought on their own - and you get all six.

Included: JBass · The Upright · Bassysm-J · Bassysm-S · Bassysm-M · Bassysm-F

Features

JBass

JBass

A four-string American Fender Custom Shop Jazz Bass with flatwound strings. Warm, round and focused: the sound that shaped funk, disco, reggae and jazz fusion, and that still sits comfortably in almost any genre.

The Upright

The Upright

A 4/4 double bass recorded from three microphone perspectives - a pair of overheads, a microphone at the f-hole and the pickup - so you can shape it towards more low end, more roundness or more finger detail.

Bassysm-J

Bassysm-J

A four-string Music Man Stingray with roundwound strings, played with the fingers. Punchy and present - the everyday electric bass of the collection.

Bassysm-S

Bassysm-S

The same Stingray, slapped: thumbs and pops for funk and for anything else that needs the bass to bite.

Discover Bassysm-S →

Bassysm-M

Bassysm-M

The Stingray again, played muted: short, thumpy notes for vintage soul lines and tight, dry grooves.

Discover Bassysm-M →

Bassysm-F

Bassysm-F

A five-string fretless Ibanez with roundwound strings, for singing slides and the vocal tone only a fretless has.
