I’m a novice bass player and a bass equipment neophyte. I play in a garage rock band that is starting to play some small venues and may one day move larger ones. My Ampeg BA115 barely keeps up with our guitars and so I need more power. I’d like some advice on possible next rigs with the following ideas in mind: - Lighter, smaller gear is much preferred as I have a mid-sized car and simply don't enjoy hauling excessively heavy gear. - I think I’d like to move to amp/cabinet config (from my combo). - I’d also like my next rig to be expandable (vs. simply replacing gear). Perhaps a larger amp with a cabinet that could added to later? Any thoughts, wisdom, advice, etc. would be greatly appreciated!
