TC RH750 part II
- Thread starter Chef
- Start date
Nope. I am currently twiddling shafts. 3 of mine have fallen off - the plastic fins on the inside seem to be disintegrating.
I've contacted them through their site - hopefully they send me a new set.

Twiddle your shaft in private, please!
I also had knobs fall off my RH750. The knobs seem designed to fail. Support agreed to send me replacement knobs. They were helpful, but couldn't tell me if the replacement knobs would be of the same design. Also, I was told that there are none in stock in the US; they have to get them from Denmark.
On the plus side, I was told the shafts are 6mm. Anybody want to recommend a good, lightweight aftermarket replacement?
I got new knobs for my GB Shuttle 9.0, but I can't remember where. I root around and see if I can find a decent set and let you know.
Were you feeding it a fairly hot signal? What about overall volume? The power management will compress like a tube amp when pushed hard. Does it happen at all volume levels?
Yeah, I never was a huge fan of the cabs, but I've had pretty good luck with the head's dynamics, so maybe the amp could work for you but just with some other cabs and maybe with some different settings? Using much eq on the bass?
Ran this amp/speaker combo with everything I had!
Active and passive basses -
Flat EQ-'Tweaked EQ -
High and Low gain -
Bass to cable to head straight path -
Ran the head into different cabs with same compressed oddities resulting.
It definitely sounded great for thumpin and loved it for picked overdriven rock! Super tight!! Great massive attack! I suspect it would lock effortlessly with a raging guitar accompanied Marshall stack! Best rock bass amp I have ever heard! I play guitar too, and most bass amps don't get that incredible tight Marshall guitar "chug".....the RH750 does!
But I play mostly fretless - harmonics, chording, glissandos, fingered vibrato, even thumpin! And at all the settings I used over a week of trials, I had to conclude that it "hid" (for a lack of a better term) the subtleties and finesse qualities that I have come to appreciate in fretless playing. Even plain ol string scrape noise was differently reduced.
After years of different amps I have used, the only way I could describe it, is that it seemed like some digital compression/interpretation (when no compression was used, added, or engaged by me) failed to capture the finesse and subtleties of my fretless.
It is a digital head with digital output. Perhaps a bit rate increase might allow the subtleties to return? I don't know; I am only guessing as to what could be the limitation or problem according to my opinion.
I would highly recommend this bass amp to thumpers and pick rockers!!!
Great head room and tone when hittin it hard! It will hit you back hard!
To some, that is a welcomed warning!But if finesse and subtle nuance is your game, you may be missing something.
I have a different experience with my fretless. In fact I could not say if I am using more and more fretless now just because I am playing more hours a week or because I like the tone of the 750 with a fretless.
Perhaps the RH750 is eating some subtle fretless nunance that you can perceive better than me (I am not recording seriously and when the sound is good enough then it is good), but in my opinion the RH750 does not necessarily dissapoints every fretless player.
There are a couple of things that might help:
-If you play VERY loud (or with a low efficiency cab), the RH750 sounds like a tube amp. Compressed. I agree, ideal for pick or certain rock, not for chords, glissado harmonics and so on on a fretless. I like all these advanced techniques in a fretless and I agree 100% they are not appropriate for a tube amp or an RH750 depending on how it is set.
-I've got the impression that if your gain is set near the point where the "clip" led lits (as recommended by manual, the setting that makes most sense to anybody) there might be some soft compression in the pre. I think my sound is cleaner if I reduce gain some 3 clicks down (my gain was already low because my basses give a very hot signal). And then using a higher master volume. I read this opinion on TB, I was reluctant to believe it. But i tried and I have the impression that this works to have a clean sound.
Perhaps this (and not our ears) makes the difference between users who can get a clean sound and people who cannot.

I agree completely with this and its the way I use the head as well. No TubeTone, no Spectracomp, low input, high master. IT yields the best sound out of this head to my ears.
I ended up liking the RS210 way more than the head. To my ear, one of the best 210's out there. Very even, nice but controlled low end, and the coax tweeter is a thing of beauty. That cab with my F500 or LMII was really something IMO. Very 'Bag End' like to my ear.
Also, I found the RH450/RS210 rig wonderful for fretless playing. Lots of warm mids and no super deep low end or sizzle to mask the 'woodiness' of a good fretless tone. IMO there, but man, I recommend that rig for fretless players to this day. Of course, I didn't run the head 'neutral'.
I unfortunely don't have a clip posted of my fretless Mouse prior to selling it, but for the OP, here is a clip of my fretted Mouse (which still has quite a bit of that woody fretless vibe) through the RS210 and TCRH450. If you have a good set of phones, you can literally hear that 'wood' coming out of that instrument.

Great rig for fretless if you like the 'mwah' of a fretless tone, due to the warm midrange voicing.
IMO!

I have sold a bunch of these things, and I own an RH750, and have had zero problems with the knobs, so I don't think it's a widespread problem. I would imagine a replacement set will set you straight, and if not, I would imagine TC would do something to make it right.
Actually found an old audio clip of my fretless Mouse and the RH450/RS210 rig, set relatively 'neutral' (no boost or cuts except for a slight attenuation of the deep low end to allow the midrange to bloom a bit more, no tubetone, no compression).
I am not much of a fretless player (which is why a swapped the fretless Mouse for a fretted), but even with my meager fretless skills you can (IMO) hear that wonderful wood and nuanced tone, the 'mwah', and that 'warmth and mid articulation' that IMO is so key to making a fretless tone work.

PS Bummer on the knob issue that the newer units are having. They must have changed suppliers, since there was never a post over the couple years the RH450 was out regarding any issue with the knobs. Seems like they either got a large batch that was not spec'd properly, or someone messed up the specifications sent to the supplier.
That rig is really made for the Rob Allen basses, if you are interested in 'wooding them up'. Really nice rig for that sort of 'mid present, warm' vibe IMO.
Thanks! I love that little bass.
Has anybody else who's waiting on one of these gotten their amp or a revised ETA? Mine was initially "mid-January," then "by the end of the month." The end of the month is about here.
Finally got a RH750 used in mint condition from another Talkbasser. Im using it for upright, a fretted jazz bass and a frettless and Im liking the sound very much for all 3 setups. I have the amp set pretty flat for everything. I had a chance to try it out on a couple gigs this weekend. With the upright, depending on the volume and room, Im rolling off some lows and highs slightly. Im playing this through a Schroeder 1x15 cab with no tweeter, and it really is bringing out the qualities I like best about that speaker cab. Playing all styles, mainly jazz standards and latin music. The design of this amp is really one of the best Ive seen. In combination with this 15lb Schroeder speaker, Ive got a great sounding, super lightweight setup that is as loud as anything Ill ever need for large venues to small clubs that Im liking with all 3 basses. Im happy.
Wow... seems like maybe you have kinda' tried everything... I guess I've just had different experiences, but I don't know why. Oh well... I'm sure you'll find something that works better for you. Lotsa' great products on the market.
