I've been playing drums for a long, long time, but I've always struggled with tuning and tuning quickly. The tune bot made this process almost foolproof. It has a lot of features that I haven't even explored yet, so that's why the ease of use is 4 stars--it's not hard to use, but there is a lot that you can do with it, so you do need to sit down and work through the features and use the websites or the app to figure it all out. You also might need to do a little math to dial in your specific setup.BUT, I'm sure this gets easier over time, and the results have been absolutely worth it. I didn't want to admit I needed to spend this much money to make my kit sound good. But, it doesn't just sound good, it sounds great, and I feel confident about the sound. The only hiccup was with tuning the snare, and that was a little odd. It just seemed to have some difficulty with some of the lug resonances on the snare head. I did take the snare off when I tuned it, but my snare has just always been a little hard to tune. That's part of why I wanted to get this gadget. But I've read that some other folks seemed to have a similar issue on the resonant head of the snare--it almost seemed like, on the higher tensions, that there were times when it just read the tension wrong, like 100 off, but I knew it was obviosly not the low reading that came up. I could dial up, and then suddenly, over a certain tension the reading just dipped by, like, 100 points. That didn't make sense. So, I kind of went with it and used my ear a bit, and I got them in line together. Overall the sound is still superior to any tuning I've done in the past. The sound of the bass drum is also much better after applying the tune bot formulas and getting real readings. I love being able to get nice intervals between my toms.The bot can save settings too, and it can adjust for multiple setups. I haven't even gotten into any of that yet. Probably one could get away with the basic bot instead of the studio. But, it didn't seem like the 20 buck different between the two was enough to get the lesser tool. Others may have a better idea of that, since I've never played with the regular tune bot.Great tool, I wish I hadn't waited to get it.
