Step 4Switching between the All-seeing eye and Ultra mods

Switching between the All-seeing eye and Ultra mods

Just a little warning - this is the hardest part of the mod.

First of all, its worth noting that it is a lot easier to not use a switch and just leave the pedal in either ASE or Ultra modes. If you just want the All seeing eye mod, you will need to remove D5 and replece it with an LED. If you want the Ultra mod, you will need to put a LED in series with D4 as well as changing D5. Difficult to get your head arround, check the diagram if you want it fixed in one mode.

Adding a switch is a little more complex, take these steps and you should be fine:

1. Undsolder D4 on the right hand side (this is the side with the black stripe on the diode)
and send that wire to the middle lug of the switch.
2. You then wire the + side of the LED to one of the two remaining lugs, it dosn't really matter which one.
The longer leg should be positive (http://www.kpsec.freeuk.com/components/led.htm).
3. Send a piece of wire from the last remaining lug and the negative side of the LED to the space in D4.

(See 2nd referance diagram)

If you are installing a new check LED, note which side of the LED was + and - and put the new LED in accordingly - if you forget or don't know don't worry it wont damage the LED if you try it both ways. Usually, most 3mm LEDs will work with the current resistor in, but if you are using a 5mm LED change R35 to a 2k4 resistor.

can someone tell me what the value of the diode is for D4? accidentally broke mine in half trying to take it off :(

the non-LED diode? u should be able to look it up on google or something based on the colors of the bands

I just finished the mods, and I have a couple of questions: 1. Why would my check light always stay lit, and my switch not work to turn the pedal off? It seems I may have done something putting it back together, I guess. 2. I think my pedal is only in ASEM mode. The LED always flashes, and there is no change when I flip the switch to change to the Ultra Mod. Any insight into this? 3. This thing is outrageously loud now. Is that normal? Thanks for the mod. Some help with these issues and I'll be all set.

i'm just a noob talkin but i think it flashes because it turns off when there is no signal... that's the pattern i noticed when i watched a comparison video on youtube. dunno about ur other question about always being in ASEM mode but i think the vol is suppose to be that loud.. cause before it was quiet and muddy.. if u watch that video you can hear that this mod will make it brighter and fuller

This was an easy mod and well written. Sounds great also!

If i want to switch between the ASE mod and the ultra mod all i do is just unsolder D4 and do what it says, and just leave D5 or do i need to still remove D5 and replace it with an LED, or have i got this completely wrong and you can't switch between ASE and ultra?

You have it completely wrong.  The switch changes between using ASEand Ultra Mode.  The switch just changes between going straightthrough D4 (ASE) or using D4 and an extra led for extra drive whichconstitutes Ultra mode.

Yep, thought it was wrong. Thanks Geeb unit :) did it how you said and its awesome!
