What is your overall opinion of this product?
First, this is a necessary DI with volume for my K&K passive pickup acoustics. Through the PA, it is very quiet and transparent. In recording, it is about the same hum as my Shure57 mic. Second, it's more than a DI with interesting tones ranging from bluegrass, country, folk, jazz, and alt for my guitar. Even string bass for my fretless acoustic bass. This is a must have for solo performing acoustic guitarist, and a great backup for those with higher-end DI boxes.
