    I have been plying bass for a while now, but never been good at setting the eq levels on my amp. I play mostly blues and classic rock. I cant find an online manual for my amp, but it ranges from -15 to + 15 in low,low mid,high mid,high, and something called contour for low pass and high pass. can anyone tell me how i should adjust theese or have any insight or link on how theese work ? thanks

    The very best thing you can do is set all the controls "flat", meaning no cut or boost. On some controls that may mean 12:00 noon, and on some that may mean fully counterclockwise, and believe it or not there are some 3-band EQ's where "flat" is neither of those settings. If you post the make/model of your amp, and maybe even a picture of it, we can try to sort that particular point out for you.

    Once you have everything set as flat as possible, just experiment. Boost a bit here, cut a bit there, see how it sounds. There are no rules except "if it sounds good, it is good". Generally speaking you want to avoid scooping your mids if you are playing in a full band, as you may become inaudible that way. The "contour" control is a mid scoop.

    Here's a bit more on the subject: http://www.ovnilab.com/articles/eqtypes.shtml
  4. I have my eq set as so:

    (This is assuming that the eq is flat when every knob is pointing upwards, vertical)

    Bass/Low = Turn 90° to the right (horizontal pointing right)
    Low Mid = Turn 45° to the right
    Mid = Leave vertical
    High Mid = Turn 45° to the left
    Treble/High = Turn 90° to the left (horizontal pointing left)

    If you can't tell, I'm something of a perfectionist lol.

    This will give you enough low mids to be able to stand out whilst giving a nice rounded tone. I use a Ashdown Electric Blue 180 combo and an ESP F-404 if that's any help.

    If your amp has four knobs just turn the low mid and high mid knobs abit more towards the top.

    Hi caspah1914.

    A lot of players set up their bass and amp EQ as follows:

    1) Make sure the bass is properly set up so that it:

    - plays well (neck relief and string height at its bridge & nut)

    - plays in tune on every note (intonation adjustment at the bass' bridge)

    - and so that its pickups are adjusted parallel with the pick-guard (this helps insure that all the strings will be amplified to the same volume) and close enough to the strings for a good string capture/strong electrical output, yet far enough away to avoid excess magnet damping of the string's vibrations (leading to a loss of sustain and weird out-of-tune harmonics).

    Having one's bass professionally set up is a shortcut to achieving the above.

    2) Set the instrument's EQ flat (if it's an active bass, if it's a passive bass turn its tone control up full).

    3) Set the amp's EQ flat (turn off any compressors & limiters and any mid-scoop or treble/bass-boost buttons which may be labeled something like 'contour')

    4) *With the bass' on-board volume turned up full (passive bass), and with the amplifier's MASTER volume turned up a tiny amount, plug into the regular input on the amp and adjust the amp's GAIN control so that it feeds the amp a good strong signal from the bass without distorting, even when the bass' strings are plucked vigorously.

    *Please note: For active basses, modify the the plug in procedure by plugging into the amp's input marked 'pad', or 'padded', or - 6 dB etc and realize that the on-board pre-amps on some active basses are so powerful that they'll overload even the padded input on some amps. If this occurs, one will have to turn the instrument's volume knob down a little to avoid clipping/distorting the amplifier's pre-amp stage.

    4) Turn up the rig loud enough to blend with the drummer, and then tweak the amp's EQ slightly to compensate for adverse room acoustics and/or competition from other instruments.

    5) If one's band is playing so LOUD that one's bass amp is close to clipping/distorting, then turn on any clipping limiter the rig may have which is designed to limit the pre-amp signal being fed to the power amp in order to prevent often speaker-killing power amp clipping.

    6) If one's band is so LOUD that after :bassist: one's ears are ringing :eek:, then turn down or get hearing protection! Seriously!

    If the above steps are followed then one will enjoy a bass and amp combination which sounds & feels satisfyingly full, punchy, tony, and largely balanced (no bass is perfect) throughout its entire register.

    It will also sit well in the mix--a mix which will sound good for years, and years, and years 'cause you'll still have your ears! :D
