I don't normally endorse products like this but I tried to get on Steve Barr's forum and it must not like our firewall so I gave up. What a PIA! BUT this is one heck of a product! Installed it in my MIA Jazz, no problems just five easy solder connections. Bigger sound difference than Sansamp for $50 more, more hi-fi, more eq range, mid shift and mid boost/cut. Bass Northwest was very easy to deal with and fast. One semi "issue" is that it makes me want to play brighter so it picks up more string noise and fret buzz. Moved my action up a little. Now if I played it flat this wouldn't be an issue , but full mid cut full treble and presense boost and small bass boost sound sooo cool! I going to try flatwounds and fender black tapewounds again and see if I can still get this bright sound.
