What diameter soundhole is needed for the SP-1/HP-1?

Date: 26.08.2021

The widest part of SP-1 / HP-1 is 4.21" / 107mm in length at the bottom of the pickup. SP-1/HP-1 may be moved slightly toward the bridge or the fretboard as long as the distance between one and the other end of the soundhole in these positions is at most 4.21" / 107mm.

The minimum diameter of the soundhole to accommodate the SP-1 / HP-1 is at least 3.62 "/ 92 mm.
