Fender TBP-1 and MB 1200 - cab support?

    I've toying with the idea of picking up a TBP-1 preamp and matching it to a Fender MB 1200 power amp. Here's the specs on the latter from the Fender website:
    The MB-1200 has six speaker outputs and runs effortlessly at 2 Ohms allowing for speaker setups including:
    (2) 810 PRO cabinets
    (4) 410 PRO cabinets
    (2) 410 PRO SL cabinets & (2) 115 PRO cabinets
    (2) 210 PRO cabinets & (2) 115 PRO cabinets

    • 1200 Watts @ 2 Ohms (same as 800 PRO and Bassman® 1200 PRO heads)

    My only concern is whether my GK cabs can support it. I've got a GK 410SBX+ with the following specs:

    IMPEDANCE: 8 ohms
    POWER RATING: 800 Watts

    paired with a GK 115SBX-II with specs:

    IMPEDANCE: 8 ohms
    POWER RATING: 400 Watts

    I know little about these power ratings and what they really mean. So, (1) does anyone know of a good source for newbies regarding this type of information, and (2) would the Fender MB 1200 pose any risk to my current cabs?

    Thanks in advance for your thoughts!
  2. No, that sounds fine to me. the 4 ohm load will get about 800watts outta the poweramp, and the speakers can supposedly handle upto 1200. I don't see any problems.

    Thanks, Son - my uneducated guess was as you say. The 1200 rating on the cabs suggests it should be able to handle whatever the power amp throws at it. It was the ohm stuff that I couldn't figure. I've gotta get someone to explain that stuff to me so I have it in my head once and for all.
