Mesa/Boogie Titan V12 megathread!

As for needing more bottom end I've never felt the need for it, running through a mesa powerhouse (4x10+1x15) in 5-string drop A.
For the delay you're experiencing I've noticed similar behavior with the drive enabled, it's more of a spongy, almost swelling effect, much like the guitar rectifiers, and I like it, its like an earthquake under control, but also not really, needless to say I really like the Titan.

The Titan has massive lows, but IMHO it's focused more in the mid bass than sub bass like the M9. The Titan is probably not the right amp if you want super deep bass, as I think the amp's HPF is fairly high.

I actually run my Titan with the drive engaged most of time, but the gain dialed way down. IMHO engaging the Drive makes the amp feel very similar to be a big tube amp pushed close to it's limit. I wouldn't call it delay either. It does sort of softens the notes and allows them to bloom, which I think is the whole idea.
 
I don't think there are any HPF in the Titan. But I'm not sure of that. Maybe @agedhorse might enlight us on that point?
However I love big massive lows. And to me the Titan was perfectly filling my needs. I used it with an external HPF to protect my cabs though.


I can't say for sure, but my perception is the Titan rolls off the low end a bit higher than many other amps in my collection. If you compare a Titan, which has a very strong low mids, to a M9 Carbine, which puts out an exceptional amount of sub bass, you would will immediately hear the difference. IMHO, most of our sense of huge lows is actually encoded in frequencies above 60hz.

I agree. The M9 feels a bit more like an Ampeg to me. And yes the Titan doesn't go as low. But for someone like me who loves cranking massive lows, the Titan is absolutly flawless.

Interesting response I got from Mesa in regard to the Titan updates which I thought some users may find informative. The rep who responded didn't seem to be aware of any updates performed on these amps, may point them in the direction of this thread.

"That said, I wouldn’t recommend purchasing one of these amps for your sole amplifier at this point due to the scarcity of some select parts. We are having difficulty sourcing some parts for these amps and it could be that at some point in the future, certain necessary parts or potential replacements are no longer available."

Such a bad news for such a fantastic amp......

Okay you guys freaked me out a little, so I called Mesa USA and got an RMA. They said they have all the parts but are no longer selling them to third party repair centers. So maybe this impacts non-US Mesa authorized repair centers.

The price for the update has gone up, and the current estimate is between $350-550USD plus return shipping. Depending upon shipping rates, by the time I am done I may be out >$700 total. If it wasn't such a unique and awesome amp I wouldn't even consider it.

:bawl:

Part of the problem is that unless you have done this update a few times, it takes a LOT of time and is easy to screw up. It just became obvious that it could be done less expensively and with less grief at the factory.

That's true, but I don't think the solution is the send an amp from Australia to Mesa in Petaluma. I just paid $144.84 S/H and I am in the US...no turning back now I guess :bored:.

I got the impression the biggest issue is that sourcing authentic MOSFETs is difficult and extremely expensive :rage:. Honestly this update is already essentially prohibitively expensive, and Mesa is probably using parts they bought years ago before the price of the MOSFETs went through the roof. So basically they need to hold on to their remaining bench stock, otherwise they won't be able to support the amp at their home repair station.

Part of it is the MOSFETs (and we still buy them, and yes they are crazy expensive, which is one reason why it didn't make sense building amps using this technology), part of it may be (depending on the rev. level) other parts, including a power transformer. These were crazy expensive amps to build.

Finally got my Titan back with the power unit update. Only 4 hours before rehearsal. :hyper:
Tested it within my punk rock / dirt rock band. And we're loud.:)
Cabs are two 2x12" SAD with respectively 1000W and 600W. Load is 2 Ohm.
Before the update it only took 10-20s for the amp to go into protection mode. :(
Now, full power ahead for 90 minutes. :bassist::bassist::bassist:
NO FLAWS!

Soundwise this amp is something special. There is a big boomy bottom which really fills the room and pillows the band. Midrange is somewhat scooped, so you have to work on the mids eq-wise, and highs are open, clear, without any bite. What really flabbergasted me were dynamics. This amp projects everything I play without upper bounds, without any power unit compression. Any accent stands out clearly. But without that clinical harshness that some silicon amps deliver. The Titan's basic voicing leaves much space for the guitarist's sound, so we immediately found our band sounding better than ever. EQing was only needed for optimization.

Altough I rated the overdrive as too sweet and soft while checking out at home, it really worked well with the band. You can dial in a good scoop of dirt without sacrificing your attack. Sorrily it too boosts the bass frequencies too much, so I ended up setting one channel for a clean sound and the other channel for a more raunchy, aggressive sound. The concept of switching clean/overdrive within one channel did not work well.

What comes into play handy is the solo switch. I use it for that occasional slight +3db-push when we go to 11. Or when I go for slapping as this technique tends to get lost when everybody goes berserk.

Compared to my Thunderfunk TFB750, which is a swiss army knife due to its elaborated eq, and which has plenty of clean power, I can say: the Mesa Titan V12 has a lot more character, it has a character of its own, and it delivers superfast 16th notes at silly volumes without any compromise. When the Thunderfunk starts mumbling and you hardly can't tell whether there are distinct notes or just one long sound, the Titan nails one note after the other.
Apparently more is better. I like big power amp units. F*** for weight.

Compared to my Mesa Bass Strategy 8:88, the tube monster has much more mid range character, it is more of a giant guitar amp, while the Titan delivers more deep bass and embraces the band. Both take no prisoners.

I agree that the overdrive circuit brings in a bit of EQ. To me it seems to add lows and takes away some of the highs as well.

FYI the amp uses four tubes and they are shared across the two channels. The two tubes on the right are always on, and the two tubes on the left are brought in when you engage the OD circuit. I haven't tried it yet, but it may be possible to modify the OD tone and get it a bit closer to the clean tone by rolling tubes.

I set up my amp with one channel in clean mode and the other in OD they way you describe. Usually I run the OD channel with the gain turned down just below break up. IMHO, this really makes the amp feel like a pushed tube amp. So basically I have one voice that is faster and a bit brighter, and another voice that is squishy and thick, with a bit more bloom.

Glad your update worked out. Mesa should receive my Titan tomorrow. They said it would take about three weeks, so time to brace myself :greedy:.

Yes it did. You're right the two OD tubes are on the left, and have a bit of bass boost when OD kicked on. I remedied this by using a pair of vintage RCA long plate tubes in those sockets. Long plates seem to not be as bassy, and keep the high end.

Did some experimentation with these three 12AX7A / ECC83: RSD, Mesa, JJ
Although I consider myself picky, I couldn't detect any tonal differences.

Just paid for the Service and Reliability Update on my Titan. Cost including return shipping came to $452. Shipping there was $144.84 so the total cost comes to $596.84. That would have been a nice down payment on a WD-800 :bored:.

They replaced the power block and power transformer, did some additional work on the power supply, and replaced a capacitor that was causing some extra hum into the high gain section of the preamp.

Another bit of news, the store that originally sold the amp and refused to provide proof of purchase so I could get the work done under warranty is no longer a Mesa dealer. I can only hope a bit of karma is involved, but their Yelp reviews are still fabulous.

Maybe I can move on and stop whining about it now :bawl:. Then again what else does a GOF have to do to pass the time since it's getting cold outside, and there are no kids in the yard to yell at :roflmao:.
 
My Titan is back from the update and repair. No perforated top panel was installed, which is a bit of a surprise. The fan noise is a little louder and the smell of fresh electronic components is strong, which is to be expected. The hum from the high gain channel is gone, and I think the amp may actually sound better than it ever has since I have owned it. The highs seem just a little sweeter and the little staticy sounds that I believe were coming from output section seem to be fixed. The amp sounds fabulous :).
