I purchased this foot switch because after buying the Vypyr VIP 1 I had confirmation that, as with any amplifier, a foot switch is necessary to move between the different channels and doing things manually isn't that great!
In the Vypyr, for guitar, you have 3 different banks and you can define 4 presets each. With the Sanpera 1 you can access all the 12 presets (3*4) , so you only have to remember what each present includes (distortion / lead / clean / crunch channel and effects).
This allows you to build your 4 preferred presets for a bank (ie preset 1: clean + reverb, preset 2: distorsion + flanger ....) and have them accessible with a simple click on on of the 4 buttons of the footswitch.
You can switch bank by pressing 2 buttons at a time and then selecting the desired bank.
Access is rather good (clicking 2 buttons simultaneusly as requested in some cases can be a little difficult sometimes, but you just have to get used to it).
Buttons are a little hard to press, at least at the beginning, and the "click" is very... loud (it can be a good sign of solid construction!)
You can also use the pedal as wah or as expression pedal for the effect you selected.
I personally think this is a must have for all the Vypyr VIP 1 owners. It costs a little less than the amp, but the amp itselfs costs peanuts (at least for me) as the sound is great, the amp is loud and the effects you have out of the box are good: in my opinion you must consider the bundle (amp + Sanpera) as a single product. And compare the cost with the cost of a decent amp + a number of good pedals: this way the value is even clearer
