I think the abz on reverb is priced on the high side. Since it’s a music store selling, I’d call and see if there is any wiggle room. Gig bag or hardcase, shipping also count for something.
I’d also want to verify what preamp it has. And I’d want them to weigh it again, because 9 lb seems really heavy for an AB. It is solid ash, so that might be the correct weight.
At 9lb, I’d pass on it, there will be better deals on lighter AB’s if you wait.
I haven’t been able to try any of the combustion or NG’s yet, so I don’t really know how they compare to the Canadian models.
I only buy used gear. Comparing a used this against a new, retail priced that is mostly apples and oranges. I think used is a far better value than new, especially if you are trying a bass out.
Eventually, the used market establishes a fair market value and a price range. Buy on the low side of the price range and you can probably recoup the price if it doesn’t work for you.
The TB classified ads are a wealth of information for researching price and how long a bass took to sell. Great deals go fast, not so great deals sit or have multiple price reductions. You can look back at years of listings.
