Home Up AMPEG SVP-Pro AudioTronics Carvin DMX MX3282A eDrum kit



These are pictures of optioning Auxiliaries from Pre Fader (Post EQ) to Pre EQ on each channel.  The existing trace has to be broken then a jumper soldered to two pads.

 It is winter and dry.  There is a lot of static build up. 

Better safe than sorry!

All new straps were tested for continuity.  And adjacent traces next to the broken/scraped off trace were tested for continuity to the nearest via's.  These continuity tests insured that I did not scrape off or break an adjacent trace.   I hate to open up a unit to trouble shoot problems or discover the problems during a live gig.
