If you've not tried a Big Block you should... they sound like they sound but ****!!!! You will NOT EVER have to worry about being heard... wherever you are...
I've always liked heavier basses and I also think the weight helps them 'sing'. Had a F'less one of these and they are [i]very[/i] nice to play; out of interest what is it you miss and want to go back to? Must be tasty to move this on for...
Got an iAmp 800 definitely does 2 Ohms (1Kw)..If the cabs are nearer 6 Ohms and the amp has a low current capable PS that would almost certainly trigger the thermal pretection.... as above try one cab.. if all is well i'd be sure that impedence matching is the issue... the iAmp 800 has a large (hence 19lbs weight) toroid for just that reason... andsounds great btw!!!
