The Pure 12-String is a passive system for 12-string guitar, with three pickup heads and an endpin jack.
This preamp allows for most precise adjustment of the individual transducers in order to achieve best possible string-to-string and overall tone-balance. It’s hard to top the already great performance of the Pure pickups, but the Tri-Star definitely takes things to the next level.
Main features of the Tri-Star Preamp:
To achieve individual gain control, we use one discrete class A operational amplifier/buffer preamp per pickup head. While the channel for the E – A string pickup is set at full range, we progressively add a preset bass-cut to the D-G and B-E channel. At the D-G channel the bass is reduced only slightly below 140 Hz. The B-E channel has a much more dramatic bass cut below 250Hz. As the high strings do not ring at low frequencies at all, this feature provides a very sweet and crystal clear transmission of the high stings that, as a nice by-product, completely eliminates unwanted pick-attack noise.
The trim-pot settings on the main circuit board can be changed with the supplied long screwdriver.
The Tri-Star preamp is available in two versions:
Both versions are available as a complete system with Pure Pickup or as preamp only.
