a bit of history...
I had a PJB rig - The Dalek - but then I got a new car. Although the car was bigger, it was a saloon, so access to the boot was smaller and my PJB rig wouldn't fit. I bought the above set up as it nicely fitted in the boot.
The combo is great on it's own for rehearsals and small gigs. It can handle 5 and 6 strings for rehearsals, but needs to the cab for gigging volumes.
I last gigged it over 3 years ago, since then it's been sat in a bedroom.
