Of the four pedals I have, which I placed next to each other for the test (Off-Set, Yamaha, Trick, and the Drumnetics) and memory of the Speed Cobra I tried out last week, the Nucleus 3 is closest to a perfect pedal for me as I have tried. I just sent Mike a long review.
If by reverse angle you mean the shaft is less than 90 degrees at impact, I could not get that, regardless of adjustments, which was the only thing that I found fault with, for me. I really dislike, and as a result, never go past 90 degrees on impact. It has always felt lax and stressed to me. Now, I set this test up against a vertical surface, not a bass drum. I always tilt my bass drum back at me enough to make sure I am less than 90 at impact. Tilting the test surface towards me gave me the quick impact feel I am used to, so ...
I tried both post positions. The forward is better. Funny, I thought you stated you had him push the posts back. He sent it to me posts placed back, and I placed the posts forward after awhile to see the difference. That pushed the beater noticeably closer to the impact surface, and also I placed the link all the way up, after trying all three settings and liked it better high, though if I played heels down the angle of the footboard would be rather uncomfortable for me, and I sit pretty high, too.
The magnets are terrific. Very sensitive. The Trick wins out on beater placement, which is very far forward on its mechanism compared to all other pedals I've owned or tried. I basically maxed out all the Tricks possible settings. Dialing in is nice. I didn't find the compression adjustments to be quite as defined as reviews I've read. Most times if I max out a spring it is way too tough for me. Not the case with the Trick. The magnets are noticeably aggressive set all the way up, but still quite controllable. Overall, though, the Nucleus just kept pulling me back to it. The Off Set is just a great pedal, too, and I actually found it easier to play faster on the expansion springs, but had more control with the Trick and Nucleus, which I expected.
The only physical problem is with the posts forward the hoop clamp bolt did not line up with its receptacle. Maybe just an oversight Mike forgot about. I didn't think about it, because I thought you liked the posts further back, but if he sent you one with forward posts he must have a post design that accommodates lining up the the tightening bolt.
I tried each pedal on my Hart edrum kick and the Nucleus won out there, too, for me. My acoustic drums are undergoing a renovation and are down right now. I am trying to finish up a bass drum before the trial period expires.
I also wondered what a longboard would feel like, and mentioned that to Mike. The Speed Cobra really surprised me last week, even though it isn't quite a longboard by design. It is quite a bit longer than any other split boards I have encountered. If the Nucleus had a longboard it would raise the heel some and take away some of the severe angle.
If I could just move that beater wheel forward 1/4" and get that beater to impact in less than 90 degrees this pedal is gold for me. The Trick is an excellent pedal, to be sure. Very close they are, but the Nucleus has an edge in those magnets and the centered design of it all. "Immediate" is the one word I use to describe the feel. I mean, Bang! that beater is on that head with more wallop than any of the other pedals using the same stroke force.
In some respects it actually surprised me that I like the OFF SET better than the Trick, being an expansion system. It is beefier than the other pedals, and with my 13EEE feet the wide footboard and weight and solid nature of the whole unit just feels really good to me. But the action of the magnets is quite unique on the Nucleus.
I generally place my beater at 12 - 13" off the floor, at center. Can't be done with the Nucleus centered cam/beater system. You only have about 3/4" inch of play there. I had to cut down beater shafts for use with the Hart edrum kick, and using one of those beaters in the Nucleus made all the difference in the world. With a standard beater I could not get the unit going as fast as my other pedals where you can slide the beater shafts up and down at will. I should mention this used Trick I got off ebay came with a Tama rotating beater, which is fine, because I like those anyway. So, I have not been able to try out the Trick sliding beater heads.
I couldn't quite warm up to the Trick footboard. The pedal came with the base slid all the way forward. Good grief it places the pedal an inch and half closer to you then the other pedals. Drastic. I tried it that way and then slid the base back and brought the Trick to the same basic placement as the other pedals, though even there the footboard is closer to use because you really can't place your toes up closer to the pivot point like other pedals. That means adjusting bass drum placement to accommodate leg angles. Not a big deal.
The centered nature of the Nucleus was noticeable to me. Not drastic, but noticeable. The Trick obviously has more adjustments, but for me, going past certain points became totally useless regardless of where you counter-adjusted in other places. Great pedal though. Almost neck and neck with the Nucleus because of beater angle adjustment. And maybe a slightly beefier feel to the whole pedal by weight and design. Cannot compare with the OFF SET, though. That thing is a tank with eagle's wings. If Charles made a single pedal I may have never looked into getting anything else. Finding the Nucleus has been a great discovery.
I also would need to affix a toe stop on the footboard. My foot just keeps incessantly sliding forward to the point of distraction. I also think a toe stop would add a little weight I miss compared to the OS and even the Yamaha with the toe stop I put on it which made a huge difference. The Yam is a rattle trap compared to the silence of the Nucleus and Trick. The OS is quite silent, too, but just a touch of spring stretch can be heard with it.
Ultimately if the beater shaft screw were placed behind the shaft rather than in front I could rotate the wheel further forward and get the impact angle I really desire. Of course, Mike has a physical stop on the motion to prevent the wheel from going past the point of being able to place a drum key over the screw head.
I also will try to place a small piece of metal rod under the footboard, magnet holding it in place, and see if the slight weight adds some oomph to the feel. Big feet are no blessing, I'll tell you. I just like some weight underneath my foot.
The immediate action of the Nucleus is really nice. BAM! The more I played it, the less the learning curve took place.
To be totally honest, after all the thinking and research I have done in the last couple of months, while the difference between expansion systems and compression systems is noticeable, it is not difficult to overcome, and one has its merits for various pedal tastes. I'm still waiting on a Speed King I got off ebay, just for comparison's sake. I grew up on that and want to feel the twin compression springs again. But I'm sold on the magnets. No gimmick there. Real pedal science. Aside from some sliding forward on the footboard, the pedal truly becomes one with your foot. Brain, foot, play action is really one, which is wonderful. I am not involved in the slight wrestling match I feel with an expansion spring, even the OFF SET to a small degree. The Trick is not a wrestling match, but the action is different by design. I tried getting the Trick and Nucleus to match. Couldn't do it. Close, but no real match in feel. They both feel nice, though.
We'll see what Mike says about all the ideas and stuff coming at him. Like he says, with all honesty and practicality, he'd never have a pedal to sell if he followed everyone's suggestions he's gotten. Trying to come up with a pedal that meets everyone's tastes and feel is impossible. I do not care what any company says. Human beings are all too different to have such a device. Ultimately we are talking nuances. Anyone with proficiency can play just about any pedal with some adjustments. Even beginner's pedals. Some just make it a little easier for players to pull off the multiple strokes and all.
Is there a bad pedal out there anymore? I doubt it. The Nucleus is as close to a perfect feel as I have gotten thus far in the search, though.
UPDATE: Just want to make sure no one has the impression the Nucleus is a lightweight. While I didn't put the pedals on a scale, in lifting the Trick and Nucleus and letting them hang by two fingers it feels like the Trick weighs a tad more. I first felt the weight of the Off Set to be more than both the others, but its right about the same I'd say, which impresses me with how it is made to feel so stout and hefty. But they all weight about the same, and truly, this hi-tech aluminum is not siding on a house. It's heavy stuff. I can only logically conclude, once the Nucleus is tightened down to a hoop its strengths of use and action will only increase.
