You may also find that you get a change in tone when the pedal is in, giving more highs. If this is the case, it is being caused by what ever you have after the TF loading down the guitar when the pedal is bypassed (when the pedal is in, it buffers the guitar). You can check this by plugging the guitar directly into whatever follows it and see if you get the same result.
What to do ? Probably either set the TF output level switch to "line" to drop its output a bit, or if you prefer the new sound, set BYP TYP to DSP – this will keep the pedal electronics active even when it is bypassed.
Or, of course, it could be something else entirely …
