I imagine a lot of gear is tough to get unless it’s high end stuff right now. There has been a ton of people picking up instruments during the shelter in place orders.
Sweetwater is significantly better than GuitarCenter though. Better customer support, better site, better warranty, better everything.
My dad used to have a recording studio before he passed away. Our Sweetwater rep (the same one the whole time)called every couple months for 13 years just to see if I need any other equipment, and to tell me when older gear I had was going obsolete due to driver support etc. fantastic experience, and one of the best companies I’ve ever bought from.
Their YouTube channel has some good reviews of equipment and Mitch on there does some interesting informed interviews with musicians. I live in the UK so can't order from them but they look to be very good sellers.
