The Trinity Mini is a dual source pickup/internal mic system with a dual-channel preamp for steel-string guitars. The three-head, bridge plate pickup is based on the same technology as our Pure pickup. The Trinity Microphone features an integrated 5" gooseneck (allowing it to be positioned in a number of ways, incuding outside the soundhole) and 20-20,000 Hz frequency range. The Trinity Preamp is a dual-channel, external, beltclip model with adjustable gain-vol-bass-mid-treb for each channel. The system comes with a stereo endpin jack and a 6-foot stereo cable--no soldering required! The Trinity Mini delivers an even more authentic tone than the Pure pickup alone. The mic adds some extra air and shimmer to the overall sound, which is very beneficial to the purely acoustic guitarist. The mic can be included in the mix as much as the situation allows for, using the preamp's controls. As a general rule, the lower the stage volume, the more mic can be blended in. This system is great for home recordings too!
