Hey guys. I did a search for this but all I am coming up with is the model with the switches, and this Growler doesn't have them. This is one Bartolini pickup, non radiused, with five knobs and one of them is a push pull. I dont have an amp here right now, and need to see if I can find out what the control layout is before my gig tonight. Thanks in advance. Bass belongs to my guitar player by the way and he has no clue.
