Trying not to derail another thread, but wondering if folks can explain how they use/under what circumstances they use amp "modeling" pedals such as the Tech 21 Character series or the Joyo pedals? Are you use them with an amp to achieve another amp's flavor (ex: using a Vox-style with a Fender amp)? Is it redundant to use a Fender-style pedal with a Fender-style amp? Using them direct to board without an amp? Just wonderin'!
