Trooper are an Indonesian company that have been making pedals for about 10 years. Formed and run by Adianus Ardy H. the idea was to make the poor man's gourmet pedal.
Hand made but utilizing cheaper but robust Asian parts. The pedals are designed around these parts and do sound damn good. The prices are excellent. The only problem is communication. They can not be found online in English.
His personal favorite pedal is War Dog.
On a final note he is a big Iron Maiden fan.
The first video shows that it can do very good 'classic' high gain sounds and the second is all about it's Metal sounds.
Pro pedal sound and for the price are a steal!!
