Don't forget that You can save the cab from any rig You have.
My favourite cabs have I saved from my favourite rigs by Guiorist, Deadlight Studio, SinMix and others.
To try out different cabs, take a rig You like and just lock everything except the cab and then You can browse the RE, search for certain speakers, manufacturers and so on...
And when You find cabs that You like just go to the cab section and hit save.
I have started doing this with ToastMe and then setting up a directory in rig manager saving my favourite cabs/IR’s.
You then just use the !Cab! Function to lock everything but the cab and then select through the list in the rig manager folder to try all the various cabs with my selected rig. Works a treat.
I just need some utility to pull out all the various cabs I have in the 1000’s of profiles in rig manager..oh well I am managing to do it a bit at a time..
