from the TLLE manual, pg 25:
10. If you notice that the volume level of a speci?c program is different from that of other pro-grams and you wish to adjust the level, press the CAB button while holding down the AMP
button, then turn the PROG LVL knob (value knob 6). You can also apply this procedure if
some effect settings cause sound clipping.
14. ToneLab LE provides a PEDAL effect [...] turn value knobs 1, 2, and 3 to adjust DRIVE, LEVEL, and TONE respec-tively. You can edit other effects using the same procedure.
HINT: Some effect settings may cause unwanted distortion (if there is such a thing!!). If this happens,
lower the PROG LVL. (p.25)
It just seems redundant to the ch volume, and i was playing with it to see if there was anything else it did.
thanks for the comeback,
