Further to my previous Roland bitch number 2: Smartarse marketing and product development.
Many of their products require specialised and expensive footswitches to operate to their full potential. e.g. The Cube 60 watt amps have 3 footswitch jacks. The cheap non-Roland switches will not work properly.) They require double clicks to perform the required function. Why Roland needed to do this other than exploitation is beyond me, to perform simple channel switching or for turning effects on or off.
Again, the Boss footswitches are NOT included, they are options. the RRP 0n a double footswitch is approximately $129.95 and on a single,$39.95. On a $600 amplifier that is equivalent to well over 25% extra.
These switches also are sold without the required cables, (more expense!)and what's more require batteries (still more expense!) which introduces a reliability factor: you wish to kick in an effect during your highlight song at the audition for that pub gig and the battery is flat. You don't get the gig, who would you be likely to apportion a share of the blame to?

My old Yamaha G100 amp supplied a double footswitch as standard.
Many other amp and equipment manufacturers supply footswitches as standard, and this needs to be factored in when comparing purchase price.
