京城大侠amon在卖他的0257802,是不是这厮搞到好东西了Problem #1-Battery Failure.
Use the current stereo output jack to complete this modification. Please do not remove the 1 Meg resistor, it quiets the "popping sound" when the active/passive switch is engaged.
To correct the battery failure problem go to the following 2 websites:
http://www.bartolini.net/1_wirngs/sterjaks.htm
Tip - "hot" connection, Ring - "battery ground" connection, and Sleeve - "common ground" connection. Go to "Wiring Diagram #1" to see an illustration.

Problem #2-Active/passive switch.
NOTE: The active/passive switch currectly on the Fender - Marcus Miller jazz bass goes through the preamp. I hear EQing on the sound, but passive tone should have no EQing. I wanted my MM bass to sound like my original 1975 and 1978, so I rewired the active/passive switch.
To understand how a TRUE "Active/Passive" switch is installed look at the two(2) following websites:
http://www.bartolini.net/1_wirngs/ppapsw_t.htm
http://www.bartolini.net/1_wirngs/tbt_old.htm
In the Bartolini old tbt diagram, the "yellow wire" is the preamp input wire. The "green wire" is the preamp output wire. On the Fender - Marcus Miller bass, the "yellow wire" is the preamp input wire, and the "white wire" is the preamp output wire.
One(1)additional piece of wire is needed to complete this modification. One piece of 22 awg insulated wire 2 inches long. Cut to desired length to make connection for the two north poles(toward headstock) of the active/passive switch. Rearrange all other connection wires to there new points of destination as indicated from the website drawings. The current lengths of these wires should be long enough to work. |
