TC Electronic RH750 ???!??

I spent a lot of time last night playing with the head (through headphones, the kids were sleeping) and I have to say it can make some really useful sounds. The compressor is great and I really like the tubetone knob--I can get just the right amount of dirt (which isn't much for me). The tweetertone thing is also very useful, and I love that I can store my presets!

More to come--but so far I am very impressed. I'm also surprised at how much I'm diggin' the built-in tuner--I've always carried a tuner with me and it's really convenient having it built right into the front face of the amp.

I'm dying to know what power modules they used in it--has anyone taken theirs apart to see? I have this need to take apart everything I own--I pulled a couple of screws today out of it, but once I got the bottom cover off (that's actually the side opposite the handle) it was clear it was going to be more than I want to undertake while it's still under warranty.

Does adjusting the attenuator on the back of your cabs (ie: Bergantino AE112 or AE212) do what the Tweetertone actually does anyway?
My question is - is the Tweetertone only a easier way of adjusting the cab ( without having to physically reach around to adjust?)
Looking to upgrade my RH450 so thought I'd see if it is worth the change ( dont really push the RH450 to justify more headroom but interested in this as a new feature)

Man I've never really understood this myself. Does the tweetertone override the attenuator on the back of the cab? Is the tweetertone more effective if the attenuator is at 0%, 50%, 100%? Good question.

TweeterTone to me seems like just another eq that works in the same range that most horn tweeters typically operate in, the difference being that it can completely attenuate that frequency range to zero. I have been tending to leave it flat so far, but I've fooled with it a bit to see what it can do and it is useful as an upper-register eq to bring out some of that high-end sheen (or get rid of it, depending on what you're after).

Thanks for that,
So in reality you could get pretty much the same effect by using the attenuator on the back of the cab or, if I am reading your post correctly, it gives you an extra EQ within the cabs tweeter range?

My understanding is that the tweetertone simply dials back the low-pass filter that is baked into the rh450 and 750 around the 5k htz mark. So when you dial down the tweeter tone you are adding the hi freqs back to the natural baked in eq.

Right, except it happens when you dial UP the TweeterTone. Really, it's just another tone control with an unusual name. For me, it adds the "snap" and clarity that was missing with their earlier design. Great amp!

So it acts like a boost-only control except instead of boosting it reduces the built-in cut?

That's not confusing at all. :rolleyes:

When set to its Max position is it supposed to be flat or is there any actual boost above flat to its range?

I don't think anyone will be able to tell us this with any accuracy without scoping it. From what I've seen in demos, it appears to me that it just opens up the top end frequencies when twisted all the way to the right. Set at noon, it appears to have the same rolloff as the RH450.

I don't think folks should get to hung up on this knob or how to use it in conjunction with a cab's tweeter attenuator. Just find a setting for both knobs that sounds good together and let's you add or remove a little sparkle using the Tweetertone knob only.

It's best to think about it more like opening or closing a valve or a window to the high end frequencies. The more you open it, the more highs pass through, the more you close it, the more you're dropping off the top, and it all happens AFTER the EQ section.

What you generate behind that, with the EQ, is what gets controlled or affected.

Thanks!

Sounds like an adjustable low-pass filter.

That's at least generally what it is, and is definitely the best way to think about its use if you understand that technical term.

Either way, in simplest terms for those who want it, it's just something that either strips off highs, or doesn't strip off highs after the EQ section.

As it's generally described, that's exactly what it is, but they haven't released any technical information on the circuit stating that it is strictly just that, so we can't be sure.

The reason I bring this up is, TC Electronic likens it to giving you a different way to achieve similar goals as the tweeter control on a cabinet. Adjusting one of those does not have the same exact tonal affect as altering an LPF, so there may be a bit more to it. I don't know.

The short answer is, just play with it as well as the other controls as you find your sound. Experimentation is king with this head, and just generally understanding what the control does (above) is probably all anyone really needs for that.

Well, yet again Im in for a wait unfortunately. My 2nd RH750 had a weird 'catching' noise from the fan as soon as it was turned on for the first time (within a few seconds).

Something was either loose, catching, or vibrating.

The amp is back with the dealer awaiting another replacement.

Man, I just want a working amp so I can enjoy it :)

I think I've only heard of 3 issues with TC heads ever, and you've had two of them! Talk about bad luck. It'll be awesome when you get it all working though.

I'm continuing to really like this head--I played it yesterday through both my Avatar 2x12 and separately through my ancient SWR Goliath I Jr. The Goliath Jr. has a completely different character to it than the Avatar, but I was able to get the head to sound great through both of them. And it's small enough to sit on the Goliath Jr standing on it's end without looking stupid, which is a big bonus.

Can't remember if I mentioned it before, but this amp is loud as h*ll. I like it.
