how to use amplitube effects only?

if you have the WAH pedal, you can load it only.  just insert amplitube from the FX bin and click on the browser and look for the WAH pedal.

ok, click on the STOMP BOX A, click on the first selection on the left, click on AMPLITUBE 3>FILTER>WAH add it to stomp a.

click on AMP A click on BYPASS
click on AMP B click on BYPASS
click on CAB A click on BYPASS

that should work, I think.
