It's just a convenience thing Jon but TBH, it wasn't planned. I went to buy a LM Tube head and there were none in stock so I just tried the combo cos it was there and it sounded great in the shop so being an impulsive compulsive I bought it. I must be honest and say that at first, I thought I'd made a big mistake but I've done two gigs with it now - yesterday was an outdoor one on the seafront at Cleveleys and it's done a sterling job both times.
It is a compromise but I value my back more than my sound.
