    Not sure if this is the right forum...

    Looking for opinions on Tilt EQ and it's usefulness and/or effectiveness.

    Define what you mean by tilt eq?

    Shelving?

    Do you mean an EQ that cuts the highs when you boost the lows and vice versa? Plain shelving EQ? Using an off the shelf EQ to manage your sound in difficult rooms?

    That's it.
    A single knob control. Frequency response is flat with control in center. Turn the control one way it boosts lows and cuts highs. Turn the control the other way it cuts lows and boosts highs.
    Generally, boost/cut is up to +/-6dB but can be asymmetric.
    Obviously more for tone shaping, not EQ.

    Ah.

    Can't say I have. Seems like an interesting idea though.

    Any standard Baxandall bass/treble control can be designed and wired to operate this way, but it is not as useful as using 2 controls, in order to tune each band independently.

    The turnover frequencies need to be common, and a dual pot would control both sections together, one pot inverted from the other.

    Tilt is really a marketing term derived from some historic circuits that had this characteristic because of the need for simplicity.

    The tilt eq is explained here:

    A james tone circuit is more functional. On the plus side, a tilt control doesn't clutter the signal path.

    Yup. It is a very simple tone control.
    Just curious if anyone has any experience and has feedback as to it's effectiveness.

    Ask any Thunderfunk user what their favorite control is.

    Bet the answer is the Timbre. It is a tilt eq.

    Nice. Thanks.
    I know there was a few pedals that JohnK built that had a Tilt EQ.

    The tilt eq on the Thunderfunk is one of the things that makes it so well loved as a gigging amp. A little twist this way or that way in sound check to tame the room and then get on with worrying about something else. It works well.

    I've got six years on a Thunderfunk. It is not for sale.

  13. I can see it as being a useful addition to the EQ panel... but I wouldn't want it to be my only EQ control for a bass amp.

    That's what the tone control does on the VB-MA overdrive channel.

    There's a shared passive 3 band for the clean and overdrive channels. The single tone control on the overdrive allows for some extra adjustment.

    The Bax on a stacked pot thing is kind cool for minimal knobs, add a switch to flip one side so it becomes smiley-frowny control.
     
  16. It is my understanding that tilt EQs are used when the gear in question either has a limited number of knobs available, or needs to be kept simple. You wouldn't desire to have a tilt EQ, if you could have a more traditional multiband graphic EQ, instead.

    I have one on my Diamond Bass Comp. It has two tilt point options. Find it very useful and extremely easy. When the room is sounding muddy I turn it to right, when I want a dubby tone I turn it to left. So it is kind of like having a HPF and a LPF hidden in just one knob. That Diamond is a fantastic pedal.

    It's also discussed in Merlin Blencowe's valve preamp book. It is useful for single-knob guitar amp tone controls.

  19. I've never heard of this type of EQ before, if there a way to do it with a single knob on a passive bass (even if it needed larger cavity than say a Jazz bass) that would absolutely be amazing for something I'm working on.

    I did stumble onto this page Passive Baxandall but it's a two pot type... Would it be possible to wire this up to a blend pot?
