SWR output's power question

Discussion in 'Amps and Cabs [BG]' started by chalie, Feb 26, 2006.

  1. I ran my bass guitar via Ampeg SVP Pro preamp right into the effect return of my SWR SRH combo ( I have no other poweramp ) with the effect balance on full but I do get a bit less net loudness so I wonder if this is the right way to run external preamp to the combo.

    Yes that is the right way to run a preamp into a head. I do it quite often to test out preamp designs.

    As to the volume loss, the output from the SWR preamp might just be hotter than the SVP. I've noticed that preamps seem to be all over the place for output.

    There might be a pad on the effect return. Try running a straight cable from send to return and see if you notice a volume drop.

    There might be an impendance mismatch. I doubt it though since the effects loop dosen't know what is going to be plugged in and probably has a buffer.
