i actually added a resister and capacitor to my guitar's volume control to make my guitar thin out more when rolling back the volume. i like the tone to sound like a clean amp simply by rolling back my volume....and the eleven rack does it well.

without the treble bleeder circuit on my guitar, the amp models tend to stay about the same as i roll back my volume.

the impedance matching feature rolls off some highs, so may try a setting like 90k to roll off the thin tone?
