Ah scary, reading! -> scroll to bottom for TL;DR and requirements for valid suggestions. Everyone else -> I too drank the kool-aid... Sure there are pleeeenty of amps/cabs worthy of replacing my Line 6 Low Down, but based on the output to weight ratio, clarity, wide dispersion of sound, and ability to be used as a full-range PA speaker, I've convinced myself a fEARful 12/6/1 is the only cab worthy of being the cab for me. This upgrade should get me through until the total collapse of western civilization. At the very least I would just add to it, not replace... Anyways, I can't decide what amp to feed into it. Since I want to stick with the one cab for as long as possible (keywords being lightweight and "affordable"), I want an amp than can push a 12/6/1 to its full extent. That means drawing 700 - 1000 watts at 8 ohms, depending on how much the amp can go without clipping. Generally, I won't be cranking it, but if I'm putting the money into the cab, I don't want it to be wasted potential I can never use. That said, the cab alone will be quite a pretty penny at an estimated $682, minus the cost of the wood. Ideally, the amp head (or separate pre/power amps) would be less than the cost of the cab. As much as I love buying secondhand anything, for a setup that'll last as long as I want, I'm hesitant to buy a secondhand amp, even though it would be cheaper. If it is from a reputable source though, I'm all for it, especially if a warranty is still valid. I'm not looking for any fancy add-ons or crazy tone-shaping. My main bass is a Schecter with dual TWXs and a BQC preamp all wired in 18V, so I already have some versatility in tone there. Though, my passive P bass (WIP) will be ready to plug and play in a couple months, so basic EQ is required. TL;DR Requirements for a suggested amp head or separate rack units: Minimum 700W ideally ~900W at 8ohms Less than $700, bonus points for under $500 Ideally tube-driven, though will consider proven, reliable digital units; Line 6 has scarred me Small/lightweight preferred, but not a deal-breaker Basic EQ controls, nothing too fancy required Speakon outs for cab, headphone out, DI send, aux in Bonus points for effects send/return I have some ideas already, but I'm casting a wide net here. Thank you for the fishies.
