What are we talking guys ?  ..... I’m a Limey novice wanting some imput from you all .    It’s all a little too tech at the minute.  See I own a Peerless Tonemaster that’s okay for rockabilly,  but it’s slightly bland normally,  until I downloaded a particular fx  and whoopee it’s great !!!  
the fx is on my small Fender mustang amp that I’ve downloaded is ..titled  “smoke on the water” .Deep Purple .... I tried it and it’s good for even rockabilly !!!! Or should I say Neil Young stuff.   I digress,  but recently I purchased a ‘cheap as chips’ copy of an Es 295 Gibson  Scottie Moore tribute in metallic blue custom ..... trouble is when it arrived after several months waiting it was faulty,  insofar as the p90 dog ear bridge pickup was loose inside the guitar and no black wire attached !!!! Now I don’t know what to do and whether it matters which way I should put it back for polarity reasons etc, as there is no indication as to where it was soldered ..... sheesh any suggestions guys would be much appreciated ?
