Comparison Ibanez RG421 vs Ibanez GRG121DX

The ability to disable one of the coils in a humbucking pickup.

Pickups with this feature are, in fact, universal modules that can operate in both humbucking and single-coil modes. See "Pickup Diagram" for details on both. And the ability to switch between these modes allows the musician to change the colour of the sound without resorting to external gadgets or changing instruments. For example, for a dynamic composition with rich overdrive, it is more convenient to use a classic humbucker, and for a slow, lyrical melody, just move the switch and you can enjoy all the advantages of a single-coil.

The presence in the electric guitar of a system of through fastening of strings.

In the classic through fastening, the body of the instrument itself plays the role of a stop bar — holes are made in it, in which the strings are fixed (from the side of the bridge). The advantage of this design is the improved contact of the strings with the body, which allows you to achieve good sustain. However, in tremolo machines (see "Bridge") there is another kind of through fasteners — when the holes are located not on the body, but on the bridge; in particular, this option is typical for Vintage Tremolo machines. In such cases, the through fastening itself is only a design feature of the bridge, and the contact of the strings with the body depends on the features of the fastening of the "machine" on the body and can be different.
