Equip Your Bass for Deep Space

The popularity of Roland’s V-Bass and GR-55 guitar synthesizer continues to spread, and the new improved GK-3B is the perfect pickup for driving these and other MIDI bass rigs. Much smaller and thinner than its GK-2B predecessor, the GK-3B is similar to its guitar counterpart, the GK-3, but catered for bass players.

  • - Thinner controller unit (compared to GK-2B)
  • - Large and smooth GK Knob for controlling volume
  • - Select Switch for selecting normal bass tone, synth sounds, or a mixture of the two
  • - Attachment holder and double-sided tape included for easy installation
  • - Compatible with GR-55, GR-20, V-BASS, and GI-20. (In October 2004, an updater will be available for download to make it compatible with GR-20.)

Read carefully before installing your GK-3B

GK-3B position* With the pickup section featuring six individual pickup coils, this unit is compatible even with six-string basses.


Requirements


between 16 mm and 19 mm(A) Make sure that your string spacing is between 16 mm (11/16") and 19 mm (3/4").

least 18 mm(B) Make sure that there is a space of at least 18 mm (3/4") between the bridge and rear pickup.

at least 138 mm(C) Make sure that there is a space of at least 138 mm (5-7/16") to attach the GK pickup. The surface should be flat and there should be nothing in the way, such as screws and volume/tone knobs. (*1) (*2).

between 35 mm and 50 mm(D) Make sure the bass's body is between 35 mm (1-7/16") and 50 mm (2") thick.

floats(E) If you do not have enough space to attach GK-3B to your bass's body, attach it so that it floats above the bridge as shown here.

at least 10 mm(F) Make sure that there is a space of at least 10 mm (7/16") between the center strings and the surface that you will be attaching the GK pickup to (*3).

(*1) Depending on your 4-string bass, you can choose to position the center of the GK pickup at a point between the 1st and 2nd strings, or the 2nd and 3rd strings, or the 3rd and 4th strings. For details, please refer to the manual of your GK-supported device.

(*2) Depending on your 5-string bass, you can choose to position the center of the GK pickup at a point between the 2nd and 3rd strings, or the 3rd and 4th strings. For details, please refer to the manual of your GK-supported device.


(*3) As a general rule of thumb, use the included spacer to adjust the GK pickup height so that you have a space of about 1.5 mm between the GK pickup and each of the strings when they are held down at the highest fret.
