Ultimate Expression Line 6 FM4 Filter Modeler Mod Service
You send us your pedal, we do the mods and send it back to you.

I have played with most all of the Line 6 pedals, and this one is just the most... fun! 
All in all there are 16 filter effects to choose from and alter to your liking. 
But we can make yours even better!

Double Presets Mod- See the stompswitch and LED at the top left?  This allows you to go from 4 to 8 presets. For example, on button A you can save a slow V-Tron effect as your first preset. Step on the stompswitch at the top left, the LED comes on. Now you can save a fast V-Tron effect as your second preset. Both presets have to come from the same category. Do the same thing with a different category for buttons B, C, and D.
Expression Pedal Mod- No need to find room for a separate pedal, this one is built in! See the stompswitch and LED at the top right? Step on that one and the LED comes on.
If we use the same example as above for switch A, now you can roll the pedal knob with your foot.  Scroll anywhere from the slow V-Tron to the fast V-Tron, or anywhere in between.
There’s just no limit to what you can with these added mods!

Complete Switch Upgrade- The stock switches on Line 6 pedals are put together in pieces  You can see that the one on the left has a spring that bumps up against a momentary switch. Lots of musicians report having trouble sooner or later with these switches. You just don’t need to be playing live and lose your effect, or have to step on the switches an extra time or two. 
We removed those cheap spring loaded suckers, and hard wired in heavy duty Momentary SPST “Soft Touch” switches (as seen on the right). These are nice! They are super quiet, no malfunctions, and built to last.

LED Upgrade- All LEDs are water/clear blue. Clear when off, and bright blue when switched on.

Note: You will need to use your Line 6 power supply!
1) Without it the mods will not work properly.
2) This adapter filters the sound to eliminate background noises.
3 Your pedal will last much longer.
