New TC Electronics RH750 or RH450?

Well.... I went with a new RH450 which arrived yesterday; I coundn't justify the extra $300 plus I figure that if I want to get the RH750 it would be best to wait until they've been out for awhile to get a good deal on a used one. The RH450 sounds great to my ears but I did discover a mechanical problem with the headphone jack... it does not work nor does it cut the sound off to the speakers. I've contacted the dealer and they've emailed TC Support so we'll see what happens next.

I'd argue why even bother with the RH750 then? The TweeterTone was a very important control for me, but it certainly won't be for everyone. If you're perfectly happy with the RH450, which I could EASILY understand, there's no need to spend another dime. :)
 
I had the same question, except I may also have the answer. :)

I noticed when I pressed the shift button on my RH750 last night, the dots were NOT all at "noon", but I didn't really think much of it until now. So other than the small boost/cut diff of the treble control, I THINK they're identical, but we're talking about the "default" vs "noon position". I'm guessing the noon position is the same, but the RH750 ships with different default settings.

In short, it may simply be that in their case, "default" doesn't necessarily mean "noon" or "center position".

I need to play more with this to verify tho.
That makes sense, and would be the only way I could rationalize having the same min/max on those knobs. Those default settings are MUCH better, and are aligned more with how I usually set my RH450 up anyway. Thanks!
 
I'd also be interested to know as I ASSUMED the default positions would be at noon when the shift is pressed. Velly interesting....
Yeah, I'm gonna' do a factory reset tonight just to make sure I'm not smokin' crack on this, but I think that is the case.

Because the only other answer is the range is not implemented linearly on the controls. While that's completely possible with their design, I don't think that would make a lot of sense from an intuitive usability standpoint, which would be counter typical TC Electronic design.

More later.
 
Yep, that's what it is. If I do a factory reset on it, the bass and treble controls are NOT at the center position. The bass control has a few clicks showing to the left, (280-200) and the treble control shows about 9-10 clicks to the right (1.6K to 4K).

So the only real difference is the RH750 has a little more boost available on the treble control. Otherwise the controls are the same, just their default settings are different.
 
I've had both the RH450 and RH750, and only kept the 450.

The 750 has its fan always running and its pretty much noisy and noticeable in a quiet environment (studio). Also, the tone of the 450 was more interesting to me, with my RS210. I feel like they went too far with the 750, packed too much in this little box... The tweeter knob can easily be emulated if you just cut some highs with the eq...

There wasn't that much power difference as well...

Considering they have the same amount of output power....
 
Do they?

I was wondering if it was just my RS210 that can't provide more volume ... But for sure, there wasn't that much difference (if any) in overall volume, and the cab didn't fart either even with the RH750 output volume at 10.

Here is Link Removed on the RH series amps.

That's the limitation of the 210 more than anything. I still have an RH450. I had a 750 also. The 750 is definitely bigger sounding through the right cab. There is absolutely no doubt about it, despite the posting of folks here at TB that want to slam it. The 750 has much more punch and authority, but you need a cab that has the capacity to showcase that. Most every 210 delivers all it can deliver in terms of volume at a fairly modest power input.

I've also owned the RS210, RS212, and the little RS210 combo cab. All of them are nice cabs. I like the baked-in tone of the RH450 very much. The RH750 does have more flexibility due to the extra controls and such, and if you want a more open sound then it will get you there. For me, the RH450 has plenty of power though, and it just always sounds great. Everyone always loves it and thinks it sounds the way a great vintage bass amp should sound.

I would say that the standard 210 would be reaching it's limitations around ~225-250 watts. Some thermal compression will come in to play before that.

Agreed. Volume differences IME with a 210 become hard to detect over about 150 watts. Transients and such just don't jump out at you if there isn't a lot of headroom in the cabinet. That is why I'm suggesting that a larger cab is needed to notice the difference. I used to run my RH450 and RH750 both on top of a dual RS212 stack, and also with other manufacturers cabs. The RS750 is quite noticeably more powerful, punchy, more authoritative, etc. TC's pdf on the power management was released to help the nay sayers, which I get. That's a whole nother discussion on what they did and if it's right/wrong/whatever. I'm just saying that there is a definite difference between the two if you use them with the right cabs.

I definitely can believe that! I had the feeling that my RS210 was the limitation...

Anyway for me, the always runing and noisy fan was the major deal breaker...
