How To Assemble And Adjust The Chromatic Endpin

How To Assemble And Adjust The Chromatic Endpin

January 17, 2018

If you've already purchased The Chromatic Endpin or would like to but want to see how it works first, you're in the right place. 

Below is a video demonstrating how to get up and running out of the box. 

If you're a reader like me, you can see the text instructions that ship with the endpin below the video.



The following instructions will show you how to assemble, adjust, and care for The Chromatic Endpin.

The Chromatic Endpin ships as a kit that includes:

a)  A notched 10mm rod which inserts into your bass like a traditional endpin

b)  A two-piece gear joint that allows the bassist to adjust the angle of the pin

c)  Two interchangeable lower rods of different lengths (4” and 6”), each with an

attached rubber ball that contacts the floor when in use.

d)  A 5/32” hex screw for fastening the gear joint

e)  Two locking nuts

f)  A 14mm open wrench and 5/32” Hex Wrench. (not included in all endpin kits)

1) Open the box, remove packing materials, and unscrew the hex screw from the threaded
half of the gear joint by hand.

2)  Align the gears by hand.

3)  Insert the hex screw into the non-threaded half of the gear and hand tighten it into the

threaded side of the gear.

4)  Use the hex wrench to tighten the screw further. Do this slowly and incrementally to be

sure that the teeth of the gears are aligned and completely interlocked. Gently rock the gear joint to be sure that the gear teeth mesh and are not crossed. Failure to properly align the gear can result in damage to the device.

5)  When the gear is correctly aligned at the desired angle, tighten the hex screw firmly.

6)  Screw the notched 10mm rod into the gear housing and rotate the notched rod to the

desired angle. Lock it in place using one of the included nuts. Use as much of the thread

on the rod as possible before locking in place.

7)  Screw the lower rod into the gear housing and lock it in place with the other included nut.

8)  Double check that both locking nuts and the hex screw are tightened firmly.

9)  Insert the notched end of the endpin in the bass and lock it in place as you would a traditional straight endpin.

10) Play and experiment with different angles as you wish.


Always check that the endpin hex screw and locking nuts are firmly tightened before using the device.

Avoid exposing the device to extreme temperatures or prolonged contact with moisture. Do not disassemble the endpin after every use—this can cause it to wear out prematurely.

Once you find an angle and setup that works for you, we recommend that you leave the device assembled when not in use.

It can be stored in the included carrying pouch.
