Anybody use a Tilt EQ?

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.

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

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.

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.

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.
