In this case from a Seagull Natural Elements Amber Trail MJ.
Steps to remove B-Band AC1.5t from Natural Elements Amber Trail Mini-Jumbo
0- remove or loosen strings so you can later get your hand into body and remove saddle
1- remove 4 screws holding preamp. pull out preamp gently. Yes there is very little slack.
2- pull out transducer cable (flat one) from preamp. It's a two pin plug.
3- the phone jack cable is looped through a tie warp but does not pass through it,
I was able to pull the loop out of tie wrap from the sound hole.
The tie wrap mount is on the bass side of lower bout wall.
The cable can be easily pulled out without cutting tiewrap.
4- carefully unscrew the phone jack collar then the retaining nut.
5- carefully pull socket assembly from the inside, through body, making sure to
not drop the flat washer and lockwasher that is on inside.
6- extract socket assembly through preamp hole.
7- with strings pulled away to clear saddle pull up saddle carefully
8- the transducer cable goes in at 6th string end of saddle, the hole in
the bridge that the transducer wire passes through should be large
enough to pull the special non-piezo B-Band transducer back through.
Pull strip up for slack and to be able to stick end of strip through hole.
9- take transduce assembly out through sound hole.
At this point you should find a brass or wood shim the same thickness as the
transducer and sit in the saddle slot before replacing saddle. If you don't you
may encounter string buzz. Now would be a good time to adjust saddle height
if you need to raise or lower it more.
Re: the socket assembly
Although the socket assembly cable is plugged into the preamp PCB, there is not enough space
to unplug it without having to remove the metal cover and the PCB from the casing..
If you want to try,
- remove two screws from one side of preamps as indicated in image
- carefully pry up metal cover from screwed side
- remove knobs and 1 screw on PCB
- this is where I gave up
I could not get PCB to move. I suspect adhesive was involved.
Now you have two holes to deal with; in my case one will become a soundport and I shall make a custom maple plug for the other without a lathe.
