Jumping from 4-5 string isn’t that big a deal. Once your right hand has allowed for the extra string in the way.
6 string has caused me issues the last few times I’ve forgotten I can’t get on with them and bought one again. I think it’s that whether you play 4 or 5 the original 4 strings are where your fretting hand expects them and so in order to play the bottom b you have to stretch up to it. Add in the 6the string underneath and my whole hand has shifted downwards by a couple of cm and this throws me off. Hopefully that makes sense.
so I find I can jump between 4 and 5 easily but not so much with a 6.
I think I bought a whole TC rig back in ‘14/15.
ive been using the genz cab I’m selling for the last 2 years though,
the covering they use does mark easily. It hasn’t been driven hard. I’ve used the 210 for pit band work last couple of years.
