Great practice and DI pedal

This was a good one stop shop for improving my practice and recording game. I still use one on my pedal board in case I need to reduce a frequency for feedback. As a DI box it is great, I think I'd be happier if the volume and gain could boost the signal, instead I need to be wary that I'm not clipping through this pedal before my signal gets to the house/PA, so I'm taking a star here.
