The Quad Mod gives you the traditional three-position tonal performance, while adding a valuable 4th pickup setting. This added tonal option turns on both neck and bridge pickups in series which is a thick and punchy tone much like a humbucker. However considering the two coils are located in completely different locations on the guitar the tone is as unique as it is useful and a welcome addition to the standard two single coil pickup configuration. Every little detail of the Custom Collection 50 Burl Burst was considered. A blend of elegance and power. We started with the highly figured burl maple top and then designed around it. The burst was designed specifically for this color with the gold set in to accent it. The pickups are hand selected to deliver a traditional tone.
