1 PRESENCE CONTROL
We liked to set this Dirty Channel control fairly high as it just helped things cut through without harshness.
This allows to send a signal with an inbuilt analogue cab sim to an interface for recording or a mixing desk live. The draw back is you can’ t turn the cab sim off if required but the results are good if you can live with that. Other wise use the Amp output.
If you’re hearing the hum of ground loop when connecting the guitar butler to an amp and pa live, this ground lift can help.
