Grainger 4 String Bass

“These basses give me everything I need for recording and playing live...all the tone, clarity, power, and feel...everything. They are works of art and great tools for working bassists,” Gary Grainger.

The Grainger 4 is the evolution of our Private Stock Gary Grainger Bass line. As the primary designer of our Private Stock basses, Gary (John Scofield, Dennis Chambers, Frank Gambali, etc.) collaborated with many bass artists, including Wyzard (Mother’s Finest) and Kevin Walker (Justin Timberlake), to create a Core PRS bass with all the character and quality of Gary’s Private Stock models but with a more universal appeal.


Knobs 1-2 are volume controls and passive/active switch:

Knob 1: Neck pickup volume. 
Down = Active, Up = Passive  If this knob is up and Knob 2 is down only the neck pickup (passive) is heard

Knob 2: Bridge pickup volume. 
Down = Active, Up = Passive
If this knob is up and Knob 1 is down only the bridge pickup (passive) is heard.
If both knob 1 and knob 2 are in the up position, both pickups (passive) are heard.

Knobs 3-5 are a 3-band EQ control:

Knob 3: Bass EQ. Functions with pickups in active mode.
Knob 4: Mid EQ. Functions with pickups in active mode.
Knob 5: Treble EQ. Functions with pickups in active mode.

The bass will function passively without batteries as well.

"The PRS 4 string is my first choice in the studio because of it's rich, deep tones and the dialable, very powerful onboard preamp. Also, I love the super strength of the neck technology which allows me to have a relatively low touch with no buzzing, tested in every climate...........Killer bass!!!!”

- Rhonda Smith, Jeff Beck

"The new PRS bass line is quite impressive, excellent tone for soloing or carrying a band. It goes easily from very nice to very nasty.”

- Wyzard, Mother’s Finest

"I can get everything that I need for recording and playing live; all the tones, clarity, power, feel...everything. It is truly a work of art but also a great tool for the working bassist.”

- Gary Grainger
