This is a really good commercial backbore giving a bright, compact projecting sound.
It really works well in commercial settings where it can cut through without too much effort.
I?ve found it to play best on shallower tops although when I?ve used on medium depth top it adds tonal colours, in fact more so than some of the larger backbores I?ve used.
Overall I?ve been very impressed with everything about this backbore. It?s well made, mates seamlessly to all my tops and sounds great.
