A DIY footswitch for a Roland CUBE

A couple of months ago I bought myself a Roland CUBE 40XL as a stand-by amp for when a gig shows up.



http://www.roland.com/products/en/CUBE-40XL/


I really like the amp (especially the clean sound) and think it is as close as reasonably perfect an amp should be:

-Fair price (paid 197€ new); 
-Great sound;
-Two (or more) channels
-Predictably reliable and low maintenance (if any)
-Speaker/Amp-Emulated recording/phones output
-Inconspicuous looks;
-Strudy build quality;
-No-nonsense features;
-Loud, and remains clean while loud (if you want it to);
...

It could benefit from a line-out and external speaker jack (the bigger 80W brother in the line has it!), but hey...For the places where I intend to play I guess these features won't be needed anyway...

The shock came in the time of buying a footswitch... 60€ average price for a Roland FS6 and 30€ for the equivalent Behringer clone? Now, that's expensive... Has anyone explained these people that foostswitches are nothing but, well, switches?


While the use of such gadget is not absolutely necessary for one to enjoy all the features of this amplifier,it sure comes in handy and is highly recommended to explore the built-in 80 second looper at its full capabilities (except for those who have 3 hands)..


But then again: 30 to 60 € for a pair of non latching push buttons ?!?!?

No way, not for my daddy's son...So I came up with this:

Not pretty but, as usual, does the trick...



BOM:

2 x momentary push buttons (the more sturdy the better)
1 x scrap plastic box (this one is from an old printer's PSU)
1 x piece of 3 conductor wire (this one I made myself by twisting 3 pieces of identical wire using a hand drill)
1 x stereo jack

CIRCUIT: (really simple)




Hope you find any use in this and remember: The quality of any of your DIY builds is only as high as that of the worse component you put into it...

Cheers!

AFTER NOTE: The footswitch will work better if you use normally closed switches. The effects and channel switching will work anyway, but the looper function will only work properly with the switches in normally closed state.
