One can purchase Crate brand bass amplifiers from a music store. Guitar Center is a great reputable music store that sells Crate brand bass amplifiers.
It is a solid bass. Nothing fancy but should be reliable. I just bought a used one and I am impressed with how solid it is built. There are gear snobs that will turn their noses up at the Crate brand, but play it well and they will quickly be put in their place.
It was made by the Eminence speaker company. This 4 0hm speaker only. The Eminence cb 154 legend is a match for replacement. Ampeg also used the same 15 inch speaker for their bass combos
It really depends on the condition of the bass and which market you sell it in. I'd estimate over $10,000.
50 dollars
It depends largely on the brand and power
An original hand built Burns Balck Bison Bass Guitar with original fittings could be worth up to £4000.00 depending on condition
I just bought one for $650.
Depending on condition, an Alembic Spoiler is worth $1500 to 2000 US.
