Thanks for your suggestions, but I think the plot thickens..

This amp has a fully balanced output at the back with a ground lift switch. According to the manual, it is sourced from the post output section and can be used with or without a speaker load.

If I was to run from the DI into another power amp and then into a speaker cab, am I going to cause any problems or damage?

Am I right in thinking that 4×12 / 2×12 speaker cabs are set to run at a certain omh and will therefore not like the double amplified DI signal going in? And crucially, is it likely to sound awful if I do this?

If this will not work – any other suggestions for supercharging the little guy?
