I am sure this has been answered before several times in these threads but does the TonePump on the Euro's come set at 100% by default?
The reason I ask is I just recently changed the strings on my 2010 Euro 5LX to the Spector stainless steel from the Spector store and wasn't really too happy with the sound. The B and E strings were really rattling and just not sounding very good so I decided to check what the TonePump was set to just for the heck of it. The guy I bought the bass from said he set it to 60% and I just believed him but boy, I need to stop being lazy and check things for myself. Mine was set to 100%
I dialed it back to around 60% and have to say it sounds much better but isn't perfect. These strings are not as tight as the previous ones that are on there so I am going to pay a visit to my Luthier (Limaguy) on Friday and have him check out the neck and action. I believe Patrick mentioned that these strings were sonically matched to the basses (or something to that extent) so maybe changing back to them caused the neck to move or affected the action.
If you don't want to read this whole boring post, the morale of the story is: Just check the settings for yourself and don't be lazy
