For those wishing to experiment with analogue effect processing on digital recordings rather than being dependent on expensive analogue emulation plugins, this is the way to go.
This machine easily lets you dial in the right amount of in and out signal you feed to your effect pedal or feed back to your soundcard so you get the best possible response from your hardware.
Of course the greatness of this technology lies in the fact that you don't end up with unusable clipping, hissing or buzzing when trying to connect gear thats not levelled for recordings.
Definitely worth the dimes if you have plenty of (quality) pedals already at your disposal.
I've even used it quite convincingly to reprocess an already reamped electric guitar signal and the results are interesting. I admit I still need to fiddle with eq because the pedals I use, affect the eq quite consequently.
I think I'm gonna stick with the creation of a wet track to blend in with the original dry track.
