The Ibanez RG Tremolo series of guitars boasts various combinations of necks, pickups and bridges making them very versatile, great playing and great sounding guitars. Not to mention they look fantastic as well. We'll start by taking a look at the necks.
The RG Tremolo series uses two necks: the Wizard II-7 and the Wizard III. Let's have a look at them.
Like all the Ibanez Wizard necks, the Wizard II-7 is wide and thin with a virtually flat fingerboard. The Ibanez Wizard necks are famed for being an ultra-fast shredder's dream. The Wizard II-7 is the 7 string version of the Wizard II. The Wizard II-7 features a 5-piece Maple/Walnut construction with a bound Rosewood fingerboard with 24 jumbo frets, dot position inlays and a 25.5" scale length. The 5-piece construction technique provides a very strong durable neck because it has two pieces of walnut running the length of the neck sandwiched between three pieces of maple, also running the length of the neck.
The remainder of the Wizard II-7's specifications are: 48mm wide at the nut, 68mm wide at the last fret, 19mm thick at the 1st and 21mm thick at the 12th fret. The fingerboard has a 400mm radius which is about as close to being totally flat as you can get.
The Ibanez RG Tremolo guitars use two of Ibanez's innovative bridges: the Edge III and the Edge-Zero II with the ZPS3Fe spring system. Let's take a quick look at each of the bridges.
The Ibanez RG Tremolo series uses two series of pickups: the Axis(AH) series of humbuckers and the INF(Infinity) series, which contains both humbuckers and single coils.
The AH27 is the 7 string version of the AH1 humbucker and is used in the bridge position. The AH27 has a full bass sound with Alnico 5 magnets providing excellent clarity in harmonics and individual notes.
The AH17 is the 7 string version of the AH1 humbucker and is used in the neck position. It provides a very responsive and full sound. It's a medium output pickup with lots of character and is great for chording.
The INF2 humbucker is used in the bridge position and has an enhanced midrange output. It sports Alnico 5 magnets for individual string clarity and has excellent dynamics.
The INFS1 single coil provides nice single-coil snap thanks to Alnico 5 magnets and is designed to be used in the middle position with the neck and bridge humbuckers in the split position.
The INF1 humbucker is used in the neck position and has Ceramic magnets which make the INF1 very versatile and responsive with warm classic tone and added output.
The INF3 humbucker is typically used in the neck position. Ceramic magnets provide the dynamic sound needed for outstanding chording and rhythm.
The INFS3 single-coil is used in the middle position and is designed to be used with the bridge and neck humbuckers in the split position. Thanks to Alnico 5 magnets the INFS3 provides the traditional single-coil sound but is still a high output pickup.
The INF4 humbucker is usually used in the bridge position. With Alnico 5 magnets, the INF4 is a brilliant lead pickup with a warm sound and great harmonics.
The last thing I want to cover is the pickup switching. The Ibanez RG Tremolo series guitars all have either a humbucker-humbucker pickup configuration(HH) or a humbucker-single-coil-humbucker configuration(HSH). All the Ibanez RG Tremolo models feature 5-way switching but it works differently for each pickup configuration. The switching combinations can be a little hard visualize so I wanted to give you a diagram(courtesy of the Ibanez official site) for each so that you can get a clear picture of each switching scheme. If you click on each diagram a bigger graphic will open in a new window.
