On the Andertons blurb for the Abasi Pathos pedal it mentions that it is suitable for 'saturating a modelling amp tone'. It also says, "Encompass the functionality of several dirt boxes in one; be it a push to a driven amp, a full-on distortion channel in front of a clean amp, or a boost in front of a digital modeller." Which made me wonder, is there something specific that makes a boost or drive pedal more suitable for use with a modeller? And if so, what is it? And therefore which pedals are best for using with a modeller?
