Ok, so tonight I took off the back of my Fender Blues Jr. just to look around at the electronics, and to see how everything looked, because I am interested in building an amp, or a few pedals in the future. But anyway, my question is, there is a wire running from the speaker into a 1/4" input where all the electronics boards are, and there are 2 inputs. So i was wondering what was the second input for.. Stereo or Mono? Maybe for an extension Cabinet or something? Im not really sure because I'm pretty much an absolute n00b when it comes to customizing/building amps. So any help would be appreciated, Thanks.

It's for a footswitch, so you can switch to the "fat" mode without going to the amp itself. It's basically like a boost switch.

Ohhhhh! Thanks for the help, I was kinda unsure about it, since it didn't come with a footswitch.. but I guess if i really wanted one i could buy one. Thanks again

No problem. Yeah, they're not too expensive either you can probably find one on eBay for like $30-$40. Maybe even cheaper.

^Yea, but do you ever use the fat switch as a boost? I use my fat switch on all the time, I love the big fat clean sound of the amp with it on.

you can build one for about $13 or less. that's $9 for an enclosure, $1 for the switch. $1 for the jack, and $2 for the wire (depending on how long you want it to be.

naw, mines always on aswell. But that's because I never wanted to pay $40 for the footswitch... too much money if you ask me. If I had the footswitch though, I would use it as a boost. Probaly wouldn't be as good as an actual boost pedal but it' would serve the purpose pretty good.

Hey greenbox, do you have a link or site for a tutorial on how build one?
Hai UG!

Haha, well I actually keep mine on all the time... No point in having it off, it sounds better on anyway. That amp has great tone and a big sound for how small it is.. glad I bought it

Oh, I don't have a link, but it's pretty simple. All footswitches are basically some kind of spst, dpdt, etc type of switch wired to a 1/4" plug.

Anyway, the links are for visual purposes, you might be able to find better prices elsewhere
Plug (any 1/4" plug will do) - http://www.smallbearelec.com/Detail.bok?no=132
Wire (any 2 conductor, or shielded cable will do) - http://www.smallbearelec.com/Detail.bok?no=86
Enclosure (size isn't too much of a factor, your circuit is just the switch basically) - http://www.smallbearelec.com/Detail.bok?no=50
Switch (You don't need a DPDT, but it's the cheapest one they list) - http://www.smallbearelec.com/Detail.bok?no=24
Rubber Feet (optional really) - http://www.smallbearelec.com/Detail.bok?no=62

Anyway, just wire the switch so that one wire is on the center lug, and the other wire is on the other. Atleast, this is how I remember it being connected (I have some extra wire, plugs, and a switch, I should really figure it out.) But I was looking at my friend's marshall footswitch (because it apparantly wasn't working), and it was wired pretty much the same. It worked with my Blues Jr. (it turns out it was the jack on his marshall, not the footswitch that was broken.)
