I am a long time drummer and will always prefer acoustic drums; however, edrums do provide excellent practice and recording opportunities. Having a wife and young son and being busy with work and life, I usually only get a chance to practice late at night. For years I just couldn't practice on the kit but then I got into edrums (note, I still gig on acoustic kits). I started with a Pintech kit that had a module from Pintech (EZ)- I moved to an Alesis D4, then a Yamaha DTX2.0 and then a Roland TD6V- the kit was nice for practice, but I was never satisfied with the way ghost notes were expressed (etiher no sound at all or way too loud even when striking very softly). I also found the mesh head too boncey to use for a practice kit, but that is my personal opion- many people love mesh heads (they are quieter, feel good, and can be much easier to play faster). Since I use an ekit to practice I really don't want it to be easier to play faster - I don't want to try to execute something on a gig (while I'm playing acoustics) and find that I can't really do it on a straight up kit.
I had a lot of experience with Alesis' D4 and DM5 modules and knew that they were solid (there are still guys using D4 with acoustic triggers- they really are solid units). WHen the DM10 came out I was very interested- especially given the price.
I needed to replace some components on my ekit (frankenkit) and decided that it was time to move to a new kit altogether. When Aleis came out with the DM10 Studio 2011 (four leg rack) I new it was time to pull the trigger- then when it went on sale a couple weeks ago (down to an incredible $799) there was no way I could NOT buy it (the module itself is $699, which I think is a great price for what you get).
I see people griping about needed to tweak it- the thing is almost every edrum kit needs tweaks before it feels and plays the way you want it too. For me, the DM10 was actually the fastest/easiest to tweak. Of course, I always used the Pintech kit with other manufactures modules and I never had the top of the line modules, but it always took significantly longer to get the other modules dialed in.
I don't think it makes since to look at acoustic and electric drums as either/or- I don't believe you can ever replace the feel of a great acoustic kit- but it is often not possible to play an acoustic kit. Also, edrums open up worlds of sound that would cost a fortune to access via acoustic instruments. Add to that recording benefits (no need to buy mics, get a good room, etc.) and edrums are a wonderful tool to have in the tool box. One drawback is that edrums do go out of date or obsolete relatively quickly (consider that I gig with acoustic kits from 1968, the 1980's, 1990s as well as from the present). AN ekit is likely obsolete in less than a decade. With this in mind I just can't justify spending the 5-7K for Yamaha and Roland's top end kits. Yes, they are excellent kits, but I don't see paying almost ten times what I gave for the DM10. Yes, I agree that you get what you pay for; however, every once in a while you do get a whole lot more- that is the case here. If you are a frustrated drummer looking for a way to practice late at night you really need to check out this kit, I couldn't be happier with it.
