A hollow chamber and side slits help to reproduce natural acoustic resonance while minimizing unamplified volume.

With an ebony fingerboard, which is a rare feature on an upright bass, and a beautiful curly maple neck, this instrument offers outstanding response as well as natural tone playability.

In addition to featuring A.R.E treatment*, the thickness of the maple bridge has been carefully optimized for this instrument. Aluminum adjusters specially selected for the SLB300PRO also provide a notable upgrade that contributes to improved response and clear tone.

* A.R.E stands for Acoustic Resonance Enhancement, an innovative process that matures the wood in a short period of time to achieve tone and resonance that would normally only be found in an older instrument that has been played for many years.

Tail wire that previously consisted of 49 x 0.22-millimeter strands has been upgraded to a more flexible wire consisting of 343 x 0.06-millimeter strands.

A flexible tail wire developed specially for the SLB300PRO contributes to soft body resonance and response that are similar to those of acoustic instruments.

The tuning machine head handles are machined out of heavy-duty stock and feature an original shape for smooth, easy operation. Overall durability and operability have been significantly improved.

An SRT Powered System that has been specially optimized for the SLB300PRO delivers even more natural acoustic bass sound. This dedicated SRT Powered System achieves the highest level of acoustic bass reality thus far achieved in the SILENT Bass™ series.

Acoustic body resonance as picked up by three well-known and prized studio microphones is realistically simulated. (SRT Powered System)

The SRT Powered System is used to simulate the response of three well-known and prized studio microphones. The microphones can be selected via the MIC TYPE selector, and the sound adjusted via the BLEND and BASS/TREBLE controls to ideally match a wide range of musical genres, ensembles, performance locations, and more.

<Three Microphone Types>

1. Rich : A highly valued vintage tube microphone that delivers smooth, well-balanced sound.

2. Simple : A dynamic microphone that is often used for its clear, well-defined sound.

3. Warm : With a different tube microphone character than number 1, this classic microphone is known for a more emphasized low range and overall warmth.

<Blend Control>

The BLEND control adjusts the mix between the simulated microphone signal and the signal from the instrument’s pickup. The blend can be seamlessly adjusted from direct pickup output with no microphone simulation to full microphone simulation when maximum depth and harmonic richness are desired.

<EQ Controls (Bass / Treble)>

The BASS and TREBLE EQ controls are optimized specifically for this instrument, allowing tonal response to be matched to a wide range of performance situations.

SLB300/SLB300PRO exterior design is inherited from the SLB200. A compact, simplified shape does away with nonessential mass and volume. An acoustic bass shaped frame and a center of gravity designed to minimize rotation further enhance playability, while the bridge, fingerboard, neck and other critical parts are in positions that require no change in hold or playing technique from traditional acoustic basses.

SLB300/SLB300PRO also uses standard contrabass strings, so the user can choose the strings that he or she prefers.

The body and frame feature an antique style finish that emphasizes the qualities of the wood and exudes a natural elegance. The finish will look and feel familiar to acoustic upright bass players.

* The wood grain will be different in each individual instrument.

When packed in its dedicated soft case, the SLB300 takes up just approximately 25% of the volume of an acoustic bass.

SLB300/SLB300PRO comes with an optimized pickup system and preamplifier already installed, and can be directly connected to a wide range of equipment without further setup or adjustment.
