Here is a listing for the popular History series NT-C3. When I purchased it used, the original pickup did not produce any sound, so I installed the L.R. Baggs M1 Active, the number one most popular pickup. I don't think I need to explain it, but it outputs the sound of the acoustic guitar itself, and the volume can be adjusted. Above all, the natural sound is wonderful. The sound has a clear outline and resonates well... It also responds quickly when you touch the strings. The appearance is also beautiful, and I don't think there are any problems with the playing condition. 6th string at 12th fret: 2.5mm This is a used item, so please understand and purchase with no claims and no returns. This is only listed on Mercari. Beware of malicious sites!
