I’ve documented a range of sustain block upgrades over the years, and they really are a great way to improve the tone of a non-hardtail bridge equipped guitar. Brass is the common upgrade for double locking bridges, and titanium is another popular option. I’ve reviewed a range of brass options from several manufacturers, and a few titanium options previously, made by Hantug Custom Guitars. Hantug have been kind enough to provide me with a couple more sustain block upgrades to review, this time a brass and titanium sustain block for the Ibanez Edge Pro bridge.
The test guitar for this review is my 2003 Ibanez RG 450 LTD, which features a basswood body, and maple neck with rosewood fretboard. As with most Ibanez bridges, the stock sustain block is made out of some sort of pot metal alloy. I compared this against the brass and titanium options from Hantug.
As with all other parts created by Hantug, the brass and titanium sustain blocks are high quality units. Hantug have done a fantastic job of machining these blocks to match the dimensions of the stock unit. The Edge Pro has cutaways in the sustain block to allow for the string ball-end holders, and Hantug have designed their blocks with two options: deep grooves for those who prefer to use the ball-end holders; and a non-deep groove option for those who prefer to lock their strings in the traditional way
The blocks are nicely machined, particularly the titanium unit with it’s etched logo, and it’s almost a shame that the block is hidden away in the guitar’s body. The only downside in the design is that the spring retainer bar is the same configuration as the stock one, and that it can hold a maximum of three springs while still having two bolts holding the bar. The Hantug Edge/Lo Pro Edge blocks allow up to five springs while still allowing both bolts to hold the retainer bar.
First cab off the rank is the brass unit, and as expected from this metal, it provides a warmer and louder tone that sustains more than the stock unit. There’s a thicker low end, and the mids are pushed more into the mix. I find that the clarity is enhanced over the stock block, and there’s a greater ability to coax harmonics out of the guitar. Comparing recorded waveforms, it’s clear that the brass block compresses the sound,which gives the perception of greater volume, and enhances the sustain.
Next up is the titanium block. Titanium provides a brighter tone that has a higher level of clarity over the stock and brass units. String seperation is amazing on chords, and the harmonic quality is pushed even higher. Titanium is bright without being too shrill, and the volume pretty much matches the brass unit. Sustain is similar to the brass, so it’s a boost over the stock unit.
Overall the Hantug Edge Pro sustain block upgrades are a fantastic option for guitars loaded with this bridge. Both brass and titanium blocks offer an excellent upgrade over the stock Edge Pro sustain block. When it comes to picking one it’s more down to tonal preference and available budget, since titanium parts are generally more expensive. The Hantug blocks are beautifully machined, and also priced well against the competition. If you are looking to push your Edge Pro equipped Ibanez guitar’s tone into new territory then definitely check out the Hantug upgrade options.
