NOTE: In keeping with the originals, certain models will produce almost no sound when these three tone controls are turned all the way down (counterclockwise).
NOTE: Not all of the original amps that we modeled have controls for Treble, Middle and Bass. In such cases, rather than simply leaving the

1.8 PRESENCE Control
This control allows you to adjust the amount of Presence (high frequency “sparkle”) in your sound.
If the original amp doesn’t have a Presence control, this will have a different function.
NOTE: Presence is a function of a power amp containing a negative feedback cir- cuit, and not all the original amps we modeled contain one – for example, none of the four Vox amps we modeled (AC15, AC15TB, AC30 & AC30TB) feature a nega- tive feedback circuit. Furthermore, not all amps that have a negative feedback cir- cuit necessarily feature a Presence control. For example, the original BLACK 2x12
–negative feedback in the power amp? Yes. Presence Control? Nope. Whenever a modeled amp didn’t have a Presence control, rather than have this knob do abso- lutely nothing, we used it to control something else. For more details on exactly what the PRESENCE control does on each model, see the explanation of each amp type starting on p.21.
1.9CH VOLUME Control
This knob allows you to adjust the overall volume of your ToneLab.You can use this to adjust the volume while preserving the tonal character, including the dis- tortion created by the Valve Reactor circuit.
NOTE: Some effect settings may produce unwanted distortion. If this occurs, turn down the CH VOLUME.
