Mesa Big Block 750 insanity!

    Sup master bassers! I've decided to purchase a Mesa/Boogie Big Block 750 and PowerHouse 1000 cabinet. Talk about signing away your life to the bank...

    I used to have an Eden WT800 for 9 years and it served its purpose but it just wasn't cut out for rock music (buy Eden if you're looking to play jazz or RnB). Mesa is the ultimate in rock tone and reliability (sorry Ampeg lovers).

    Anyway, since the Mesa site didn't have any info on stereo or bridged-mono modes for the amp I decided to call them and speak to someone who knows the sh*t. The guy I spoke with tells me the BB doesn't have a bridged-mono mode; in other words, if I decide to get another PowerHouse 1000 one day (2x4ohm for 2ohm load) the BB doesn't power the 2 cabs at 375W each, it powers EACH cab at 750W (for a total of 1500W)...

    ... *shivers* ...

    This sounds too good to be true. I'm so blown away by this revelation that I felt motivated to talk about it here, either to create awareness for others (to pimp Mesa) and to see if anyone can corroborate this fact. I heard 750W per channel from the horses mouth... can anyone vouch for this?!?

    Thanks!

    Not exactly... it pushes 750 watts at 2 ohms; you actually are only pushing 375 watts with the single 4 ohm cab and won't get 750 until you actually get the second cab.

    I'm really hoping the Mesa rep didn't tell you otherwise...

    No no... amp specs are:

    550W @ 4 ohms
    750W @ 2 ohms

    He said with the single PowerHouse 1000 (4 ohm) I'd be getting 550W to one cabinet and if I run a 2nd cab the load would become 2 ohms (to the head), thus each cab getting 750W (for 1500 total).

    My question to him was about bridged-mono and he said the amp doesn't do bridged, EACH channel gets the rated power based on the the ohm rating from connected cabs.

    I thought the bb750 was a single channel amp

    It is. You can still split the power between two cabs though; as with all Mesa amps.

    And yes if you run two PH1000s the total load will be 2 ohms. The wattage isn't doubled. It's halved. 750/2 four ohm cabs gives you 375 watts per cab.

    Personally, I never found the BB750 all that inpressive. M-Pulse blows it away, especially with the 5-band semi-parametric eq. Theres no tone you cant get out of that amp (well...except for Bass 400+ tone).

    But if you're going to spend $1300 on the BB750, why not go for the all tube Bass 400+??

    No solid state amp (sorry, but I still think of an amp with just a preamp tube or two as solid state) is worth signing your life away. Tubes, on the other hand, have caused many a soul to be to be sold. Worth it? Ask those who have done so. They will say "yessss..."

    Congrats on the amp. I A/Bed the Big Block against the MPulse with that same cab. I wound up getting the MPulse because I found the tone had more character and I don't ever use overdrive. But its a good amp. And the Powerhouse 1000 is a monster of a cab. Enjoy.

    Too much hip thrust
    Whatever it is, you are good. One of my fondest memories was playing through an M-Pulse 600 and a Powerhouse 1000 one gig.

    Actually I will say "noooooo.." :D

    Tube bass amps are not for everybody. I finally sold every tube bass amp I owned...at one point I had three heads and two combos.

    BTW, I never sold my soul for tubes...the most I have ever paid for a tube bass amp was $500. Yes, I bought all mine used. I'd recommend that to anyone, let someone else pay for the right to put the first scratches on it :p

    Actually Im glad they're not for everybody. It means that I will sound even better by comparison :rolleyes:

    I like the used route myself. 2 of my tube heads were bought with money from selling my 400+. I won't put the 400+ down at all, but I like having gear that you don't see everyday.
