BB SERIES
Applying the advancements in knowledge, technology, skills we've gained since the introduction of our BB basses over 30
years ago, our BB bass design team has reinvented a legend. The new BB basses deliver exceptional tone and resonance
using a no compromise passive, bolt-on design that raises the bar for quality and performance. Exclusive features deliver
powerfully rich tone, excellent attack and sustain, immense volume, and overwhelming presence.
The series is available in three lines, the custom shop 2024 and 2025 models which are already being played and praised
by professional bassists around the globe; the production version 1024 and 1025 with specs nearly identical to the 2000
series for players particular about their sound; and the 424 and 425 which delivers many of the same features found on
the high-end models along with great cost performance.
A.R.E. (Acoustic Resonance Enhancement)
A.R.E. (Acoustic Resonance Enhancement) is an original wood reforming technology developed by Yamaha.
Instruments made with woods processed with this technology produce a tonal richness that is like vintage instruments
that have been played for years. This technology is currently applied to the BB2000 Series (pages 25–26) .
A.R.E technology uses precision controlled humidity and temperature to
manipulate the molecular properties of the wood into a more acoustically
ideal condition (similar to the molecular characteristics of woods in
instruments that have been played for years). The process is chemical
free making it an environmentally friendly process as well.
The following alterations lead to their corresponding acoustically ideal
conditions.
• Enhanced low range sustain produces rich sound and thick tone.
• Increased high range response and decay produces a sharper tone
and simultaneously controls dissonance.
The graphs shown to the right are from actual acoustic spectral
measurements taken under controlled conditions with an untreated BB
bass and a new BB bass with A.R.E. Notice the enhanced low range
sustain and the leveled mid-low frequencies that deliver a smoother
and well-defi ned sound on the A.R.E. bass. It is also clear that high
frequencies have a shorter decay after the attack providing sharper tones.
This is hard proof that A.R.E. is effective at producing the desired changes
in the wood's acoustic characteristics. These instruments have received
high marks from a great number of bassists. Most of their evaluations are
identical to evaluations for basses that have been played for years.
