Boomy F Note

    I've been playing my Mark Bass Little Mark 800 & MB Standard 104 HF cab and loving it. However at our last gig, (the first time that I have used my MB amp at this venue) whenever I played an F on the E string it sounded awful... really boomy. The open E sounded fine. For all of my other live gigs with the MB, I've been setting the EQ flat, the gain at 10:00 and volume to taste. The VLE & VPF are off. I am playing a Fender American Jazz 4 string with custom 60's pickups. String gauge is 105-45. Both pups are on full and the treble is a little less than 3/4. Any suggestion on EQing, etc?

    Sounds like room or boundary reflections to me. Happens to me occasionally, too, though the note varies with the room.

  3. When a room dimension is a multiple of the wavelength you get a resonance at that frequency. You would be looking at 26ft or 52ft most likely across the room.
