I was looking at an amp and head with the expectation of adding a second cab when I needed it and had space again. But, I bought my last amp in the mid-90s and things have changed a bit since then. Combos actually seem really good now, being lightweight and having a smaller footprint than in the past. Many have the ability to add a cabinet too. I played with a 410 cab in the past and it was loud enough for everything we did in my old power trio. I play pretty much all genres so versatility is a plus. Current bass is a Jaguar PJ with a focus on the P at the moment. My budget is up to $1000, but I have $650 in hand and would have to wait until after Christmas to get that higher total. I'd like an amp now since I am currently using an old Crate guitar practice amp. You can hear it in a room by yourself, but it sounds like crap, obviously. I do need some other gear and the after Christmas money would be good for that. This amp will be my only amp for a while, so it will be used for practice at home and carried to rehearsals and gigs in small bars and halls. A 210 seems like a great starting point to me. Class D is all new to me. How does it compare to the old, heavy solid-state heads like a Peavey Mark III in power? Combos I have considered: Fender Rumble 500 - $600. Very popular, lovely lightweight, can add a cab but I fear the tone may be a little muddy. Ampeg BA 210 - $500. The Ampeg sound suits me well, can add a cab, little heavy at nearly 50 pounds, $100 cheaper than the Fender but slightly less wattage. Hartke HD500 - $600. I like the Hartke sound. No speaker extension so it's 500W through 2 tens. I worry about the lack of air I could get from an extra 210 cab, but should I? About as light as the Fender. Blackstar Unity 500 - $650. This amp has so many bells and whistles and I think it sounds pretty good. Can add a powered cab (limited to a 15). On the heavier end of the lightweights at nearly 50 pounds. I know absolutely nothing about Blackstar so, are they any good? GK MB210 - $800. I like how they sound. I can add a cab and or a powered cab. 39 pounds, but it's a brand I am unfamiliar with aside from the talk here. Is it worth waiting for this and spending more (your opinion, I know that's a subjective question)? Ashdown Rootmaster RM500 - $800. I think I like how they sound, but can't hear one in person. A lot of artists I like play Ashdown, but they get custom jobs to tweak their tone so that's not a true indicator of what I'll get. I know nothing about the brand personally. Can add a cab and weighs around 40 pounds. Again, worth the wait and cost difference over the lower priced amps above? I figure if I am spending more than $800 I might as well look at heads and cabs as even some decent sets come in around $800 (Ampeg Portaflex, some Hartke and Peavey, etc.) My local shop only carries Fender and Blackstar. I am very familiar with Peavey's sound from the mid 80s - 90s. I am very familiar with the classic Ampeg sound. I like the later 3 more than the Fender Rumble tone, so if that helps anyone aid me in comparisons, great. Slightly OD tones are nearest and dearest to my ear. Any and all input would be greatly appreciated as I am really wanting to get an amp soon so I can really get into bass again. Thank you.
