alternatives for a hyper bass pedal?

[atomburst]

ive been looking at adding a dualist pedal to my e-kit just as something to muck around on but i dont want to buy the official dualist pedal because it is way to expensive for what i will use it for so i came across a hyper bass pedal. more info available here http://hyper-bass.com/

does anyone know if there is soemthing that is sort of the same as this or how i can achieve this a different way?

thanx

The Hyper Bass conversion is cheaper and fits on one of your own pedals.

I have played around with a lot of these double bass units and only the Hyper Bass works for me.
