Help with circuit bending a Boss DS-1.

So I decided to circuit bend my Boss DS-1.
I have a schematic and "how to" thing and to me it is a little bit unclear.
Here is the site:
http://www.instructables.com/id/Circuit-bend-the-DS-1/

The pedal: http://i46.tinypic.com/fyfrzo.jpg
Shows the base point and my variations.
A sounds like a synth, B is a cool lo-fi thing with a little feedback and C is a self-oscillating thing.
The switches: http://i45.tinypic.com/200a1ic.jpg

Question number 1:
Can I only use one mod or can I use three? Can I turn them all off and have my standard DS-1?
I have modded my DS-1 with the modern dist mod and it sounds awesome so I would like to have that possibility.

Question number 2:
Should I solder the wires from the topside of the motherboard or the underside?
I don`t really know how I would pull the wires from the underside to the topside since there is no room.

Question 3:
If I can have 3 mods should I solder all the variations to the same base-point and put a switch between the base-point and the variations?

Just wanna make sure that I understood everything clearly you know.

1:
you can use all three..I doubt they'd work in combination with one another, but you can have the option of all three at least, that'd be no problem (see question 3)

2:
wherever works for you. you can't really fit two wires through the holes in the pcb, so the easiest way would probably be going from the bottom of the board and just making sure you have a solid connection

3:
sort of..what I would recommend is getting a mini rotary switch. something like this

that switch has one pole and 6 throws, but you only really need four (one for each mod and one for the regular ds-1 sound)

you'd just connect the pole of the switch (the lugs labelled 'r' in the diagram) to the base point, and connect throws 1, 2 and 3 to one of the variations each. the unused positions will just be your normal, current ds-1 sound

Thanks!
So I should just solder all three variations to the base point?
And since I have three SPDT switches I just have to use one for each variation. I`ll have your advice in mind for the next time thou.

you shouldn't have all three variations hard-wired right to the base point, but just have the switches in between the base and each variation, so the connection from the base point to each variation can be turned on and off

that may be what you meant, but the wording is just a little strange

no problem about the three spdt's though. i've got a ds-1 with five mini switches and an extra knob crammed in, so you should be able to fit three with no problem- I just figured a rotary would be a cool way to do it

Sorry for being unclear, English ain`t my first language.
This is the way I`m planing to solder the stuff:

Is this what you meant?

I think that it should work that way but hell, there will be a pretty big solder blob at the base point.

yep, that's what I meant

to avoid a big solder blob and three wires sticking out of the base point, you could do something like this:



then you only have one wire to the basepoint, but it all functions the same

Man you are awesome! Thank you!
It`s my first time bending stuff you know.
I also found out that I can turn my cheap Vox Wah Wah into a distortion pedal.
I could post a video of the results here when I`m done with it ;p
