This pick up is dynamite. I have built over 200 GBG's and for the last 60 have settled on the 750 holler. This has worked very well for me. So I decide to try a BK200 with split coil. This is a really lively pickup which responds well to the split coil, tone knob, and the setting on my amp. I sell 90% of my guitars at craft fairs. I will have to be very careful with the volume when demonstrating this one. Thankfully I fitted this to a box with a 3/8" lid. Thankfully, because I think this might over power a thin top. I bought two more in the sale and may try a thinner top. Has anyone else tried this in a thinner box?
