From the picture, it appears i will need to do some soldering. is the trigger complete, or is this dyi?

Will my acoustic kit be converted to electronic just with this kit or do i need something else too?

How many triggers do you get? Do you get enough for a five piece kit or do you have to order five of these

Is this just for one trigger or for full kit
