Hi, The bad horsey is exactly a Wah wah, just a truncated range, so it doesn't have as wide a sweep frequency that a Dunlop or Vox has.
Harmonizers : I'm not familliar with the Roland model, but Rocktron made a unit called the intellipitch which had up to 4 voices of harmony.
Other units are by Eventide, Digitech, or T.C. Electronic.
All have modes in which you select which key you're rooting in and what scales you plan on playing in. from there they do the rest. THe eventide is VERY flexable in that you can create your own algorhythms for harmony and reverb presets. thos units are kind of pricy.
You can find a cheap Digitech IPS33 for under 100 on Ebay.
Not even close to the abilities of the Eventide or T.C. , but its a start and will do the job cheaply.
hope this helps,
