Just got my pod hd500x and I realised that when I play open on the low B of my bass (through any amp mod) the pod plays a note slightly lower than what it's meant to then after a few moments slides up to the right note. I played my bass just through a few EQ's on the pod and they picked it up fine.
Also the tuner doesn't pick up the open B string so I have to tune on the octave.
Any help would be appreciated.
