Sounds like he is still hitting hard. I have had several pairs of rods and they are still completely whole! He is hitting them harder in order to make the same amount of sound a stick would whacking a snare drum. It is one of the loudest drums that drummers can get wrong so easily. He would be better off using sticks and playing quieter. Rods sound better played softly. Then you really hear the sound of individual rods contacting the snare head. Although a very fast flam say this sound is easily picked up if the stroke level is not too loud either. You can capture this sound and to sounds killer. Fat. The note is wider. Whacking a rod is more akin to using a single solid tip.
Try this experiment. Try letting a stick fall under its own weight from about 6" up. One end of the stick should swing on your finger about 3" up from the edge of the head. Listen to how much sound it makes. Well, the snare drum has something to do with it too. A Sonor snare
(wood or steel) sounds loud doing this! A drummer only has to add little more energy to snare drum strokes in order to achieve quite a high volume in the whole room. One can wish.
I am in an interesting situation now. Mixing a tribute show. They do three sets one for Orbison, a British song collection say around 60's and a 70's American song collection. I am enjoying pulling a good FOH sound while not to have to sweat the music. The drummer I am working with has a Pearl electronic kit with nice pads triggering. The snare is electronic too. He uses real hats though and sometimes a real crash and ride etc. This sounds very nice and natural as well. He has the electronic cymbal hitters as well.
(Note the original balance from him was wrong though. Electronic kit Drummers also don't know how to balance the kit pieces leaving a drum brain. Drums need to be all in balance. Keep the reverbs to fast and subtle effects. Setting velocities is real important to your playing style and dynamics. Hats and cymbals mixed right down and add some crispness. Many brains have amazing production processing that is going on inside) It still takes the same amount of time to set up an electronic kit as it does for me to set up my Sonor kit.
Got to say though. Once you get this right the drums can sound amazing. Out front and on stage too. I have got full drum brain PA splits in stereo from him of course. He can fiddle his monitor levels without interference to me. Drum sounds are very consistent now from venue to venue as well. Once I get the PA out front sounding nice to the room
(a la Steely Dan ref mixes out front tell you everything!) The drum sound tends to slot right in with a minimum of fuss.
Now this sort of thing does allow more control over the overall stage sound. It takes a surprising amount of amps and speaker power would you believe to achieve anything is remotely close to a loud Sonar kit say. Our drummer has two monitors next to him. One on top of the other. Both powerful active full range boxes. The drums come out of the lower one for him and he is letting himself mostly hear it too. So this is good. It also creates quite a nice amount on stage for the rest of them. Not too much though. I have three foldback mixes and the drummer is one of them. His top speaker does the vocals and the rest of the music. The others all have nice active wedges and I can slip some drum sounds into any of them as well. This all does work rather nice and you can control the amount of stage sound. Still got a reasonably loud guitarist and bass player to contend with which can sometimes over power the PA, but I can usually keep them under control. They are nice fellas and listen to me. We are using backing tracks too which the drummer controls. He wears one headphone in this situation to hear the click. The backings out front are clear and in stereo too. I have mixed them. I blend them into the live channels. The line between the backing and the band is real blurred there too.
The fabulous thing about this though is his ability to switch entire kits to suit all the songs involved. You can carefully go through all your set lists and call up a range of kits. Not major changes all the time either. Keep some kicks while changing snares etc and toms. Some of those big Orbison numbers need the fat deep rock 80's snare like
She's Got It. But in the 60's Beatles stuff, that older English rock kit needs to be pulled up, and it can. The 70's American disco songs need some change ups too. It's all good and the kit changes can add a lot of colour to the show.
