Thunderfunk 750 owners unite! round deuce

Cool.

How's the DI on the TF750?

It is VERY good, Neutral and VERY quiet! I don't use it much because of the way I have my rig setup. I go from the bass to the Neve pre where I do all my basic processing and then I send the XLR line out to the Console or snake, the DI output to the front of the T-Funk which I run more or less flat unless I have to adjust for the room (I do use the Enhance and Timbre knobs to fatten the cab) and the insert send of the T-funk is used to feed my tuner...

Peace,

Tommixx, very interesting findings. I JUST received my TF-750a last night, literally when I was walking out the door to the gig. So, I decided to hold off til tonights gig to give it a good run. Right now, I have the TF750a, DB750, and Carvin B1500 which I will be A/B'ing with my Berg AE410/AE210 stack. So far, in my living room, the thunderfunk sounds REALLY REALLY good. At first, I couldn't get a good tone, but I started tweaking a few knobs, and let me tell you..that timbre and enhance knobs are a god sent! I can fatten up the tone Soooooo much. I'm really digging what I'm hearing so far. Tonight will be the ultimate test, I have a gig with the "LOUD" band, and I'll be putting the TF750a thru the paces. From what you say about the NV215/TF750a combo, it makes me want to take the NV215 off the classifieds! I'm still fighting with myself to sell it because it is one of my top 3 favorite cabs. The only reason I wanted to sell it, is because, like you, I have way too much gear right now, and it's not getting used much.

I've owned one of the TFB-420's, one of the TFB-550A's and 2 of the TFB-550B's.
IMO the TFunk is without a doubt the best bass amp available. To be honest, I didn't need any more power than the TFB-420 but I did want the mute sw. and the ss/tube sw., so I upgraded to the TFB-550B.

I don't see a TFB-750 in my future primarily because I just don't push my 550 any where close to it's power limits and I don't like running any amp @2 ohms.

Of course for those that need a little bump in power and/or have a requirement to run @2 ohms I'm sure it's cool thing. It's just not worth the upgrade price for me.

Jome; for me (and maybe some others) the 550 wasn't that big of a jump from my trusty 420.
The added power and headroom seem to be doiong great things for tone...so, those things, plus 2 ohm ready now make the 750 worth moving to for me.

I actually bought a TF550B and sent it back because I didn 't think it was enough of a bump up to warrant the change. i gotta tell you though the TF750 is a LOT more than just a power increase. It is like a different amp, but in a good way. All the things I love about the 550 are there but the TF750 is airier, fatter, and crisper, and quieter than the 550. I think a lot of it is the change in the caps, fan, and the transformer. The 750 gives you all the note size of the DB750 and you just can't do that without the transformer. I still lusted after a DB750 with the 550 (and bought my 5th one) but after this little test I lust after it no more. In fact, I am seriously thinking of trading my DB750 for another T-Funk 750!! Hope that helps Chef!

I've read where several other TB'ers stated the same thing about the 750 (airier, fatter, and crisper, and quieter than the 550) so I guess there must be something to it.

I'm sure it brings some nice enhancements to the table but at the used prices for a TFB550B (~$900) I would have to spend roughly $600-800 to upgrade to the 750.

If I'm not going to run it at 2 ohms then I'd be paying $600-800 more for roughly 75 watts more @4 ohms. I doubt that I'd hear the 75 watt difference (and even if I did I'd also hear the sound man yelling at me to turn down!).

It is a pretty dramatic difference IME. I was a bit surprised when it beat out my DB750 side by side as bad as it did... It was obvious not only to me but to the non bass players there 2! Keep in mind this was a DB750 that had been tweaked with 4 Black Swamp NOS Telefunkens too! Give it a shot if you can, you won't be sorry...

Peace,

Should be 200 more watts at 4ohms I think.

There have been a few higher powered amps that seem to crush you, but the nuances are masked. It is almost like they are too 'hyped' sounding and lack detail in the tone.

The ThunderFunk 750A is the best of both worlds. It is LOUD yet it still delivers the goods. Compared to the other TF offerings, the 750 is more open and airy sounding. The mids seem to be more refined. The thing is--I never thought that there could be an improvement in the TF tone, but the 750 is a huge upgrade.

 

[KJung]

Argh... me too

I've grown to love the more transparent, wider tone of the Markbass heads versus my TF550b... more deep low end, and a nicer, crisper less clacky treble response to my ear and still plenty of mid punch. But the build quality, the features, and the unique warm mid punch voicing of the TF550 has always been great to me.

It sounds like the 750 will expand the low end a bit, which is good, but my guess is the upper treble will still be attenuated (which may or may not be an issue, depending on the player's tone goals). I'm think strongly about it though.

I really still love the matchup of the TF550 with my Ag DB112's.... just warm, punchy and tight. I'm not sure those little 112's would be able to take much more than the TF550.

I'm intrigued by the TF750a/Berg AE410 matchup though... that seems like it might REALLY be a good one!

Considering I just had to sell mt TF750, I hate you all right now

I used my TF 750 last night on a gig through a Dr. Bass 115 cab, 4 ohms. Never had to turn the master beyond 4,a nd that was too loud. Fender '62 AVS Jazz with TI flats.

Man, one of the best bass sounds I've heard in 30+ years of playing bass.

This amp SO reminds of an Acoustic 360/361!!!

Highly recommended!

Any tips on EQing the amp for a P bass? Seems a little to complex with the Precision. Loves my jazzes though.

Glad to hear it worked for you. I always start with the EQ flat and use the Timbre and Enhance to get me where I want to go EQ wise but depending on how low mid to mid heavy your P is you may want to cut the low mids about 6-9 db and just sweep the frequency knob until you find it and then adjust up or down from there. It seems the more low mid growl the bass has the more you want to either add some bottom or cut a little of that mid out. I had a similar experience with my Glaub the other day. It was like a pi$$ed off pitbull it was so growly I think I turned about 400hz down about 2 or 3 db and it was perfect. Good Luck!

For what its worth the TF750 and the AE210 is one of the best 10's sound I have ever heard! The NV215 and the AE210 together through the T-Funk is the schizzle!

Peace,

T

tommixx: "does it help?"

depends if you're asking my personal opinion, or my credit card limit

what I hear from you current users is: the sonic difference is waay more than just the watts.

the only thing that concerns me about this: the TFB420 is my favorite Double Bass amp. I hope the changes in the 750 don't somehow take away from that.

LOL! Not what I meant...I remembered your PM (I had forgotten I hadn't responded to it until I saw your post here) and was hoping that this answered it. I really don't think you would find it changes in any way for the worse. I LOVE everything about it now. The only real thing I could complain about before was the size I got out of the DB750 versus the TF550. This absolutely KILLS the DB750 IMO now but also sounds "better" to me at the same time. The sonic difference is amazing as well as the sheer size it is able to produce.

Peace,

Ok , I finally received my TFB750a and I was able to use it at the gig saturday night. I paired it up with the Bergantino AE410/AE210 stack which was running at 2.67 ohms total. I was playing very loud, about 4 on the gain(high as I could go b4 clipping) and 6 on the master volume. By the end of the night, after 3-50 minute sets and 4 hours, I placed my hand on the amp and it was hot, really HOT! I had the fan in the ON position ALL NIGHT. So it wasn't because the fan wasn't on, I even checked it a few times for air flow. When I placed my fingers under the amp, on the left side, it was so hot that I couldn't leave my fingers on the metal for more than a second or 2. It was scorching HOT! I've never had an amp, besides a tube amp, get remotely close to being that hot, especially the metal chassis.
So, the following day, I proceeded to remove the top cover, and sure enough the heat sinks are located on the left side, right by the fan, which makes sense. They are attached to the bottom of the chasis, which would explain the heat, but I don't think it's a good thing that it would get scorching hot. I know heat, just IS NOT GOOD for any electrical components. Has any one else ran at or near a 2ohm load? Found any heat issues at all? When I feel the fan, i can feel it working fine, but the air flow just doesn't seem like much to me. I may look into replacing the fan with one that can move more CFM of air flow.

I have all 3 amps at the moment, and I have used all 3 with the Berg AE410/AE210 stack at 2.67 ohms. I can contest that the Thunderfunk is my favorite!!! It's lightweight and has massive output can compete with the DB750. I didn't do a direct A/B like Tommixx, but it is literally ALL there, all the massive low end, girth and substance to every note, and punchyness of the DB750. The only other amps that I have personally tried in this category are the DB750, B1500, and Crest CA9. This amp is lighter, smaller(it fits above the AE210 perfectly), and it has MUCH more tonal capabilities than the DB750 and B1500. I can get so many different tones out of this thing, it's the perfect "cover band" amp. I still like the DB750's burpy tone slightly more, but the pro's of the TFB750a bring it over the top. The Carvin B1500, is a nice amp with alot of mojo, but it's just slightly too SS for my tastes. If you read my above post about heat issues at 2 ohms, this is a minor concern at the moment because I really like this amp alot! It may be normal, I don't know. The timbre knob is really something else. Just a slight tweak, and I can add sooo much mojo to every note, without having to tweak the EQ all night.

Yeah Ken, i hear you. Sometimes i'd like my Tfunk to be a bit 'wider' and not compress as much. I occasionally use the Sadowsky outboard pre/DI to help fatten up my passive jazz but it would be great if i could just dial it in on the amp when i want... I'm seriously considering it now...
