Active Bass without using -12dB switch?

    I've got a Musicman active bass, and an Ampeg B2 200 watt 1 15'' combo. Basically an Ampeg B2r in a combo.

    This amp has the -12(or so)dB switch for active basses, and I get a better tone with the switch off, not to mention louder, but the 'Peak' light usually goes on. Is this bad for the amp?

    Not really bad for the amp, but not good for the speaker. You should be fine without the 12 dB, but adjust it so that the LED only lights up occasionally.

    Try turning down the gain. It is ok if the peak light fllickers, but it shouldn't flash. If you cannot get it down to a flicker with the gain control, you will have to use the -15 dB pad.

    I am very surprised that the active switch is affecting your tone. I would have expected it to be a very clean buffer with no colouring of the tone.

    I never use the active inputs or pad on any of my Ampeg heads. what the others said is right on the money. Just turn down your input gain until the red light flickers on your loudest heaviest playing. Then turn your power amp gain/stage volume up until it's loud enough.

    Yea, I use the -0db input on my BA115 w/ my Lakland 55-01 ALL the time... Since I'm not cranking it up too much, I don't worry about it. But, the sounds is definately better.
