Oh... I only wanted more low end :(
Any trick there?
I may contact TC about it for future products heh.

Buy a different head:) Again, it 'is what it is'. Very nice, warm, loud, punchy head, but like any other head, it has its own voice that is hard (or in the case of the RH750) impossible to 'dial out'. You can smooth that low mid bump a bit with the EQ but lowering the shelving start point on the bass control and boosting, and cutting the low mids a touch arond 200hz. However, that won't change the actual low end extension, but will 'flip' the ratio of low mids to upper bass, which will give the impression of a more open, wider low end.

If you are looking for extended low end in a micro, the Markbass 800 series, and the GK MB series both have a very open, deep, low end. I guess I would just say, depending on your cab, be careful what you ask for:)

Thanks! It's a pity there's no store with GK's near :/
At this moment I have an RS212, about being careful do you mean that if the amp dials out low tones perhaps the cab can be damaged?

Not so much damage IMO as a flubby, non defined tone (not a problem with the GK stuff though), and a head that spends too much power trying to reproduce deep bass that most cabs can't even use.

1. That's right, you don't need to worry; and that has nothing to do with SMPS, which this also presumably has.

2. It's actually limited to 236 watts at 4 and 8 ohms. There has been an awful lot of controversy regarding TCE power ratings on this this forum. There are probably two main take-home messages from this: 1. TCE should have done a lot more to explain their power management module at the time of the series release and not misrepresented their power specifications, and 2. power ratings mean very little with respect to loudness.

Thanks a lot !! :hyper::hyper:

Here is TC's drawing of APM smart technology at work, cutting the peaks that the human ear/brain does not really use to give you perceived loudness, and using the resulting surplus power to boost the frequencies with low level to give you a more even frequency response thus you experience a louder tone overall (technology adapted to the human biology, I like that):

And here are the (not so important) hard power numbers:

It's an interesting approach for sure.

EBS is coming now out with a new 250W class D head which they say will sound much louder than its power ratings due to some smart power management. Look for the Reidmar at the EBS web site Link Removed.
The Reidmar have very nice modern design. They chose to make it physically larger then other class D amps in this class, looks about as big as a SVT 7 pro.

I wonder how the Reidmar will sound compares to the TC450 which is a 236W head with the same technology.

I would doubt VERY much that the technology is the same. EBS, for some reason, has always been a bit behind the curve with their 'power per size' ratio. Nice stuff though. I was unimpressed with the output of both my HD350 and especially the TD650.

So where is that info buried on their website? I tried to find it and couldn't.

I had not seen this info before today either. Perhaps it has been updated since my last search. Also, that is my first reading of specs that include the BH500, which I own (and could not be happier with) now.
In addition to that, and the discussion of the "baked-in" sound of the RH750, I have yet to try the RH750. But, where I made the same observations with my previously owned RH450, the BH500 seems to have an entirely different voicing. Not lacking on the low end, and easily capable of going "clean" or not-so clean. It could be just my ears hearing it that way...Or perhaps the cabs that I use, Hartke HyDrive 112's (X2). I have no problem getting a vintage sound, or hi-fi modern, with everything in between. :D

I do not know much about EBS amps. My step son has an EBS T90 valve head, rated at 100W. It sound like it is rated decently.
Any way, it is he first amp that is non TC to be using this kind of power management, will be interesting to see what kind of voicing it will have compares to TC and other class D amps.

That does not have any impact, since again, the low end is kind of 'set' in the unit, via whatever circuitry they use. However, to my ear, it sounds like a hi pass set pretty high. Since I was given the software that allowed you to lower the hi pass filtering, and the amp got significantly deeper and wider down there, it again seems like a design goal (the vintage thing) versus any physical problem or shortcoming. It again tightens a cab up to give you that 'fridge' sort of experience, no matter what you are playing through, for better or worse.

I liked it quite a bit for some contexts.

Ah, OK. Got it. Thanks, Ken.

I would also agree that the TC does what it does and trying to get a different tone out of it might suggest its not the head for you. I just picked up a Classic 450 and the voicing is IDEAL for me. However I know its not ideal for everyone. Its a friggin loud 236 watts though!

With the right cabs, I could see the 750 being a serious contender for a lot of guys.

Especially if you use the extra features like the headphone out, which was very nice.

The amp does what it sets out to do. The design is slick.

I really wanted it to work for me, but with my cabs, the five string basses, and my need for clean as well as the tube sound, it just wasnt my cup of tea. No big deal, that's what tryouts are for.

In my enthusiasm, I bought a super nice TC gig bag that of course arrives the day after I ship the amp back. I'm on a roll now!

Anybody who might want a gig bag, check out my soon to be posted ad in the amps for sale classifieds!

Thanks, and carry on!

Yeah I can see how it wouldn't be right for a lot of guys too. If the sound doesn't suit you it's better to get rid of it before you become addicted to its awesome feature set. There are so many amps out there I'd like to try but then I imagine living without preset EQ's, A1 headphone amp, tuner footswitch, etc etc....

But yeah - as KJ has said before - it you find yourself fighting hard AGAINST the amp's natural tone then you're backing the wrong horse.
