Onboard Trinity Western Standard

Onboard Trinity System

The Onboard Trinity System is a dual-source pickup/internal mic system with an onboard preamp. It consists of:

• Our award-winning Pure pickup, a bridge plate pickup that provides warm and natural tone.
  
  
• The Trinity microphone, featuring 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. Technical Information for the Trinity Microphone (Opens in pop-up window)
  
  
• The onboard dual-channel preamp, specially designed with K&K's "Silent-Filter-Technology." Individual adjustable Gain-Vol-Bass-Middle-Treble controls are available for both pickup channel and mic channel.
  
  
• The system comes completely assembled with TRSS stereo endpin-jack wired in MONO so a standard guitar cable can be used; no soldering necessary. A self-adhesive magnetic battery holder and a volume control unit for inside-soundhole-edge mount with individual thumbwheel-pots for mic and pickup is also included.
  

How is the Onboard Trinity System installed?

The photo shows the preamp circuit board and its EQ-ing capability. The board is installed on the bottom of your instrument with Velcro. It measures only 2.5" x 2.75". The circuit board has a metal backing but it is fully open to the top to allow for adjusting the EQ trimmers. It is designed to be preset to perfectly balance the pickup and mic in your guitar. It offers powerful +/- 20 dB EQ without the necessity to cut a hole in your valuable instrument. You can place it either directly under the soundhole for easy access with a long, small-blade flathead screwdriver or you can hide it deeper in your guitar. This system does not require any destructive alteration of your guitar other than the installation of the endpin jack.


Two Onboard Trinity models are available:

• Onboard Trinity Classic (for nylon-string guitars)
  
  
• Onboard Trinity Western (for steel-string guitars)
  
  The Onboard Trinity Western now comes standard with the Mini pickups. The 1/2" diameter Mini pickups will fit ANY steel string acoustic guitar. Direct installation with superglue is required for optimum performance but the system is still removable without damaging the guitar (you may damage the pickup though). Installing the pickups is a breeze with the included mounting jig, detailed instructions, and superglue.
  

The Onboard Trinity System can also be custom fitted to other string instruments. Call us at 1-800-867-8663 x808 for questions and more info.
