    My 550 is making a "ocean" sound from Vol. setting 4 and gets louder as you go to 10. The Gain does not affect this. Is this normal? I usually play with the Gain high and volume low so that may be why I didn't notice it before. Again, is this normal before I send it in for repair?

    I get this as well. It's a bit more pronounced with the limiter on, and with the Gain up. Also, you can hear each of the frequency bands in the 'ocean' being amplified when you turn up each of the parametric EQ ranges. This is just the ambient noise at the phone plug and in the preamp. I'm not sure I've heard an amp that won't have some of this 'ocean sound' when the preamp is cranked up.

    Do you have another amp for comparison. I'd be curious to know whether you can 'hear the ocean' with Aguilars, AIs or Walter Woods amps as well.

    No other amps. My gain doesn't affect mine at all. Just the Vol. and the noise gets louder as it's turned up.

    I had a similar issue but I tracked it down to my bass pickup, not the amp.

    Sometimes I even pickup radio stations with my bass .

    Mine's dead wuiet, and engineers and sound guys have all commneted on how quiet the DI is. I think you have other issues...perhaps shielding in your axe, noisy electricity issues, cable issues. I'm very happy with my TFB420 in this regard, and find it to perhaps be quieter than my eden bits...It could also be your horn attenuator needs to come down a little?

    I get this with all the cables pulled. On the outputside I have Accugroove Tri112Ls (attached with Planet Waves speakon to speakon 5' cable). These have a pair of tweeters. These may need to be turned down (I'm not sure quite how to do this)

    What do you mean when you say 'noisy electricity'. Is this something that, e.g., a Furman power conditioner might clean up?

    I don't know if this helps or not but this is from page 2 of the owners manual:

    'a small time delay is built in to the limiter to prevent it from "riding" the low frequencies, causing an audible "pumping" effect. Using any limiter or compressor will affect your sound, so you should adjust it by ear.'

    Is the "ocean sound" noticable when you play?

    I just sat in front of mine and tried everything I could to hear the ocean.
    I couldn't hear it.

    I wonder if power has anything to do with it? Maybe plug in at someone else's house and listen again? (This is just an ignorant guess!)


    Keep us posted. especially if you solve the mystery.

    Good luck,
    Chad

    Yep, that's a possibility. Try another rig and see if it's effected before you shell for one tho....

    I'm playing thru a EA Wizzy, so no horn. I left the amp on a little while last night and the sound went away and is still gone today. It wasn't a tweeter type sound. It was more like an AM radio sound that wasn't set on a station.

    It does it with or without cables plugged in. I can hear it thru headphones with everything else unplugged. I've heard it other places too.
