From what I have learned on this site, Australia prices are killer for bass players. The SVT 1000 should work out well with a 410.

680 watts at 8 ohms would work great in a band situation. Do not skimp on a cab though. This head will be useless with a garbage 410. 4 ohm power is 1000 watts.
As far as tone, you need to try it out. If it is based on the B-2RE tone style, the mids are scooped at around 600hz and the 40-60hz region is boosted with the knobs at noon.
