These mods worked for ashbass and are not guaranteed to work for anyone else. Some modders have ruined their pedals.
Most agree that too much heat, or heat left on too long, burnt something up. Some symptoms are the lights at the top of
the pedal not working. And of course, the pedal not working.
So if you are going to do the mod, you are doing so at your own risk.

I've decided lately that I want all of my G5 mods together in one enclosure.

I want:
     ashbass Patch Select Mod
     ashbass Tap & Rhythm Mod
     ashbass Scroll Button Mod
     ashbass Bank Select Mod
Zoom G5

The G5 has 99 banks of 3 patches each. When you hold down foot switch 4 you enter patch mode. Now you can use switches 1, 2, and 3 to select a patch.




You can also use the Patch Select buttons located in the row of buttons at the top of the G5. These buttons work in both Patch and Effect mode.

I'll use the buttons for the Patch Select part of this mod series.

You can set Tap Tempo by pressing the Tap button located at the top of the G5. You can also set Tempo while in Rhythm Mode and through the Global menu.

You can enter and exit Rhythm Mode by pressing the Rhythm button located at the top of the G5.

I'll use the buttons for the Tap and Rhythm parts of this mod series.

There are SCROLL buttons located at the top of the G5. Pressing either button will scroll the display in that direction.

You can also press foot switches 1 & 2 simultaneously to scroll left, and press foot switches 3 & 4 simultaneously to scroll right.

I'll use the foot switches for the Scroll part of this mod series.

There are two ways to change Bank. When in Patch mode, you can turn Knob 1 of panel 4 to move up/down in the bank list.

Also in Patch mode, you can press foot switches 1 & 2 simultaneously to Bank Down and press foot switches 2 & 3 simultaneously to Bank Up.

I'll use the foot switches for the Bank part of this mod series.

The enclosure for these controls needs to accommodate 10 wires and 7 switches.


The following steps show how to do this mod yourself.

This mod needs 10 wires coming out of the G5 and into your enclosure. You'll need
   4 feet of 10-Conductor cable
   4 momentary SPST (or DPDT) switches
   3 momentary DPDT switches
   2 stereo (3-Conductor) jacks
   2 stereo (3-Conductor) plugs
   1 4-Conductor (trrs) jack
   1 4-Conductor (trrs) plug
   1 enclosure



From www.iec-usa.com
  10-Conductor Cable by the Foot
   markertek (below) has cable as well.


From lovemyswitches.com
  Momentary SPST
  Momentary 3PDT
   You can use 7 DPDT or 3PDT
   switches to save $ buying in bulk.



From markertek.com
  3.5mm 4-Conductor Snap-in Jack
  3.5mm 4-Conductor Plug
  3.5mm 3-Conductor Snap-in Jacks
  3.5mm 3-Conductor Plugs


Enclosure
  I cut a 2" diameter plastic pipe in half and
  will use one 14" half as my enclosure. A great
  idea from the User Examples page.

Remove the screws from the bottom of the G5 and put them aside. Remove the back panel.

The G5 has two circuit boards that we need to move so that we can access the circuit board beneath them. The green one on the right covers up the Patch Select buttons and the brown one on the left covers up the TAP and RHYTHM buttons. Click the image to see a larger version. Zoom G3
I drew a wiring map to help keep me from getting lost once the soldering began. Zoom G3




I chose now to install the three jacks and drilled three holes in the back of my G5.

I cut off about one and a half feet of the 10-Conductor cable and stripped it so that it's wires could easily reach the jacks and solder spots they needed to reach inside the G5.

Following the wiring map, I ran the 10 wires though the new holes and attached them to their respective jacks outside the G5.

After using a multi-meter to verify that each jack's lugs were connected to the correct colored wires I pushed the jacks into their holes until they snapped into place.

Unscrew the three screws circled in yellow. Zoom has used copper tape for shielding and ground in the top right. After removing the screws carefully pull up the strip of tape that is connected to the circuit board. It will tear easily.

Unscrew the nut from the Control In jack on the rear panel.

Unscrew the two screws circled in yellow.

Unscrew the nuts from the jacks on the rear panel.



Carefully pull the circuit boards away from where they were connected before so that you can see the board they were covering up.

Rhythm, Tap, and Patch Select
The dotted yellow circles show where the solder spots are for the Rhythm, Tap, and Patch Select buttons. Click the image for a larger version.
Zoom G3
Solder three wires to the solder spots shown in the image. The red wire is hot for the Rhythm button. The gray wire is hot for the Tap button. The green wire is common to all of the buttons on this strip. Zoom G3
Solder two wires to the solder spots shown in the image. The orange wire is hot for the Patch Up button. The yellow wire is hot for the Patch Down button. We don't need a third wire because green from the step above is common to all buttons on this strip. Zoom G3
Bank and Scroll
Flip the G5 around so that the rear of the pedal is facing you. The dotted yellow circles show where the solder spots are for each of the four foot switches. Click the image for a larger version.

Except for FS4, for each pair of solder spots the one on the right is hot and the one on the left is common to all. FS4 is the opposite.
Solder the ends of five wires to the solder spots as shown in the image.

Here, the black wire and the white wire are responsible for Bank Down and Scroll Left. The white wire and the brown wire are responsible for Bank Up. The brown wire and the blue wire are responsible for Scroll Right. The purple wire is shared by all the footswitches. You should have left to right Black, White, Purple, Brown, and Blue.

Strip enough wire from one end of the remaining 10-Conductor cable to accommodate the three plugs.

Use the wiring map to make sure that you connect the correct wires to the correct lugs on the plugs.

Here I tried to stagger the cable length of the plugs so that they will line up with the new jacks in my G5.

Measure and drill the holes needed to house 7 foot switches and then install the switches.


Pretty it up with some graphics.

Wire up the switches.

The Rhythm, Tap, and Patch Select buttons share the green wire as noted above. The switches I used for these functions are all SPST and only have two lugs. Jumper the green wire so that it is soldered to a lug on each switch. Solder the functions' hot wires to the other lugs.

The blue 3PDT switches share the purple wire as noted above. Jumper the purple wire so that it is soldered diagonally to two lugs on each of these switches. In the image below the purple wire would replace the black wire.








In place of the green and red wires in the diagram to the right, use the black wire and the white wire for Bank Down and Scroll Left. Use the white wire and the brown wire for Bank Up. Use the brown wire and the blue wire for Scroll Right.

Screw the back panel on.

All finished.
