Today I did a main band rehearsal using the Laney and a single 2x12 as an experiment.
Despite appearing a clone of the TE (similar graphic, pre-shape, parametric EQ) I had to set it up very differently to get a good tone, lots of bass boost and I found I had to use the neck pickup a lot (I mostly use the bride PUP alone on a Jazz). Even with the graphic boosting all frequencies (especially bass) found myself running at with master volume at about 80%, which is roughly where I used to have it for gigging with two 2x12s. I do vaguely think this was my old rehearsal setup. I normally run the TE on 1 or 1.5!
But, it did sound OK and will be fine as astopgap for small quieter pub gigs.
I'm increasingly minded that the best solution will be a pocket sized 300 or 500W class D as a backup head and a high efficiency 1x10 or 1x12 for small gigs.
