Does anyone have any experience with the new source pickup from Upton? There are quite a few negative comments about the revolution, and this is basically a revolution pickup imbedded in a bridge. But the demo on the website sounds pretty convincing to me. Specifically I'm wondering how this will affect the sound and feel of the double bass acoustically. It seems like a huge component of getting a good sound out of the "wing" type pickups is getting the proper fit. I wonder how this translated to the embedded pickup style of the focus. My current plan is to get an exact replica of my current bridge made and have the pickup installed in that second bridge - that way in case I hate the sound or it drastically affects my acoustic tone I can always go back to the way things were. Just thought I'd try to get some feedback before I plunk down a bunch of change for a new bridge and pickup. thanks!
