I use a Terror 500 and one sp212 and no problems.
I ,ve done open air festivals,pubs,clubs with no problems and the usual comment is how rich,big,huge,loud the sound is.What I,ve heard through the monitors when I,m in the PA is amazing DI,d from the head,they are fixed now,
When your in the PA your at the mercy of the sound man I,m afraid,don,t like what they are doing -slap em about a bit,although most of them are struggling to tame geetards wall of sound , drummers wanting more kick and vocalists wanting a bit more reverb.
I actually like the sp212 cabs and I used to use 8x10 ampig stack.I would not go back to that big stuff.
If you would like to donate your sp212 to a good caring home I will cherish it and look after it and gig it at least twice a week.
I have a powered speaker with a 15" and use as a monitor for the drummer now.
When I play pubs and clubs I have no PA support and never struggle for oooomph.I,ve stood in the middle of the room while my mate ws having a go and was amazed at how loud and good sounding it was out front .
I have noticed that it fills out the sound if you turn it up a bit ,10.30 to 11 0clock on the volume and 10.00,10.30 on the gain and it just fills up but it,s loud at that.Turn it up a bit more and it,s seriously loud and full but not boomy
Well done being no longer a newbie.
Sp212 cabs are like marmite along with Ricks,thunderbirds which are amongst the basses I use n I love Marmite as well on toast-mmmmm
