The L.R. Baggs iMix Onboard is an onboard retrofit stereo mixer, which combines the iBeam bridge plate transducer and the Element undersaddle

pickup with an all-discrete class A battery-access preamp. The system is a drop-in retrofit upgrade that is designed to fit in the hole used by several

common factory-installed systems.

We recommend that this system be installed by a professional dealer/installer. We do not provide installation advice or support for home or

hobbyist installations. Installers: please read the instructions carefully before proceeding. We will not be responsible for any damage to the guitar

or personal injury resulting from installation, improper installation, use or misuse of the product.

Before beginning a retrofit installation, be sure that the screw holes in the iBeam preamp bezel (mounting flange) line up with the existing preamp

screw holes on the guitar.

The iBeam fits x-braced guitars with at least three inches of flat open space directly under the saddle (see figure 1). For new installations, the preamp will generally fit in guitars with a side width of four inches or larger, assuming average lining and top thickness. Again, verify that these requirements are met before making any alterations to the guitar. If the space is too small to accommodate the iBeam, do not cut the iBeam to fit a tighter space.

each of the screw holes and then drill out the holes using a #45 drill bit (.082” or 2.08 mm). Cut out the area for the preamp carefully and slowly using a rotary cutter with a sharp 1/8” cutting bit. We recommend cutting just inside the lines for the initial cut and then cleaning up the edges with a file. Remove the template and clean up any excess tape residue with a soft cloth and naphtha. 4.

Though the Element will mask some of the characteristics of a non-optimum iBeam placement, we strongly encourage the installer to invest the necessary time to perfect the iBeam as a single source. This will have a significantly positive impact on the overall mix. The iBeam is designed to attach to the bridge plate, directly under the saddle line and generally parallel to the saddle, with the attached peel-and-stick adhesive.

instrument. An unsatisfactory location will often be characterized by a woofy or nasal tone, poor string balance and a high sensitivity to feedback. 8.iBEAM INSTALL ATION: NON-PIN fig. 6 BRIDGE 8.1 General positioning guidelines: The iBeam is a highly sensitive pickup; therefore, placement and the unique characteristics of the instrument are critical factors in producing the outstanding results of which the iBeam is capable.

The optimum location will deliver a sound that is focused and tight, with proper string balance and good presence. It will capture enough of the string resonance to be articulate, but will be mellowed by a full and strong body resonance. Ultimately, it will accurately capture the distinct tone of the instrument. An unsatisfactory location will often be characterized by a woofy or nasal tone, poor string balance and a high sensitivity to feedback. 9.

Important: The fit of the saddle in the slot is the single most important factor in this installation. It is crucial that the bottom of the slot and the lower surface of the saddle be flat to make even contact with the pickup. The saddle should fit loosely enough in the slot that it can be pulled out with your fingertips. It will then have a slight forward lean when the strings are under tension.

3. Mix control: The position of this knob will determine how much of each pickup's signal will be present in the overall mix. When the knob is turned completely counterclockwise, the output will be 100% Element; likewise, when the knob is turned completely clockwise, the output will be 100% iBeam. For most situations, the best position is 12:00. 4. Treble and bass controls: These controls adjust the level of high and low frequency output. 5. Phase: This inverts the signal phase.
