Sweetwater and Vintage King have alway been up and down as far as shipping time goes.I'm usually happy or pissed on any given order.
Could be that Sweetwater is being stung by the employee shortage thing. They employ a butt load of people there.
With the live music scene starting back up, they could be getting buried with orders too.
Sweetwater keeps a shit load of inventory in stock while VK does not but they have more locations to draw on.
I prefer VK for most stuff and I'll live with and extra week or two to get it from them but for the run of the mill stuff, Sweetwater or Amazon is great because of their liberal returns/exchange policies.
There's always the less visible sellers like Musician's Friend, Pro Star Audio, etc.
