Grovers are installed on my last three guitars. Simply elegant, stout, and affordable (below left). Below right, the Schaller Roller bridge has also been my choice for the last three guitars. The string rests in a tiny groove on a wheel. The wheel can move with the string when the Bigsby B3 tremolo is played. The wheel may be fine tuned both left/right and forward/back. Wheel posts lift one end or the other. Set your fingerboard arc to the 12 foot radius of the bridge. Take a very close look at any other roller bridge before you buy something else. They may vary in adjustability, overall dimension and diameter of posts. Note that primary acoustic sound transmission is through the posts. That's where the bridge rocks (...and rolls). I built a rosewood arched pad, which is free from the top in the middle just like a floating bridge. This pad is glued, not floating. See interior braceworks in Lady Sprite Acoustic Design & Construction.

The Black Ice Overdrive creates distortion for the harder rock tunes. It is installed with a mini-switch to select either "warm" or "industrial strength". Pull the tone knob out and the pot becomes a variable control for either selection. I like "industrial strength" with the pot set to 3/4 strength. This passive device means no battery required. Use the black three-way switch to select either or both of the GFS P90 pickups. I really like the P90's. They "grab air." The maple blocks into which the pickups are installed are copper foiled lined and grounded to prevent single coil hum. The Bigsby B3 (below right) comes with simple instructions and a red string to help align the tailpiece. The blue tape protection is my idea. Note the mini-switch between the B3 and the lower soundhole. The pickups and bridge ground safety circuit are soldered to the main harness, and the harness is installed, through the lower soundhole. All carefully planned in advance.

A mockup circuitboard is used to orient and wire devices (below left). It also helps organize nuts and washers. Note things like knob turn direction and wrench sizes. (Black Ice not shown) Below right, use blue tape and a scrap of soft cloth with duct tape on one side to protect the finished surface at harness install. Note the copper foil lining of the pickup cavities, grounded to prevent single coil hum.
