In the opposite boat. Trying to go smaller.
Lifting, packing and carrying large heads and wheeling 8*10 cabinets around on Saturday night are not my gig. In the home studio, I just want nice tone. So for live gigging, take weight into consideration.
I've run a Genz Benz GBE 1200 and 750 with a Genz Benz Uber 8*10 cabinet. For my needs, it is a little heavy to move around, and way too loud. Looking to move to a 2*12 cabinet at some stage.
My recommendations are based on the latest and greatest technology, bang for your buck, weight, and build quality.
Bass Heads
Probably the biggest improvement has been in the weight department. You can get micro-heads from GK and Genz Benz now, some of which are nearly small enough to fit in your pocket.
Never under-estimate the value of having a lightweight bass amplifier head. Specifically, I am talking about these heads:
Gallien Kruger:
GALLIEN KRUEGER GK MB FUSION , 500 WATT HYBRID ULTRA LIGHT AMP | Bass Centre
The watts-weight ratio is extreme and the GK tone is exceptional.
Genz Benz:
Streamliner Series | GENZ BENZ
Both amps would have a tube powered pre-amp with 12AX7 tubes. So check the weight of the head before you buy. You may really appreciate these as working player's bass heads.
Bass Cabinets
Here, I recommend two lightweight cabinets:
First and foremost, a Bergantino Neodynium speaker cabinet 2*12 is probably the best cabinet on the market at the moment.
Secondly, a Genz Benz Neodynium NX2 series, also 2*12 -
Genz Benz NX2 2*12 Neodynium Speaker Cabinet
The only issue with Genz Benz is that they have been bought out by Fender, are hard to get, and they may not exist too much longer if Fender kill them off like they have been known to do.
But for quality of build etc and tone control, I love owning them, and can only say they are some of the nicest things I have ever purchased.
Because of your budget, these products may not be your first options, but if you can make some money playing bass, they could be worth saving up for.
I hope that gives you some ideas.
