I need some help quick. Ive been reading on this board about how some iranian test is fake. It has something to do with the logo on the amp. On some amps the logo is in line with the 'IM' and on others its just below. Also I have 2-3 amps out of date by 6 months. Ive read some of the threads on this but im still unsure if I have fake stuff or not.
