I am seeing the same thing. The less expensive stuff still seems to go pretty quick but the higher end items are going more slowly.
I’ve decided to abandon my Electric Upright Bass playing, and focus on my bass guitar playing. I have come to the realization that they are two completely different instruments, despite the fact that they are tuned the same. Therefore, I have listed my EUB on Reverb for a very good price. It’s in “Like New” condition.
Fender Rumble 100 in “like new” condition.
I’m buying my friend’s 500 watt amp head and 115 Cab, so I’m selling my Rumble 100
Dang, Pam! Have both of them already sold?
LOL I took the EUB off the market, and the Rumble just sold.
That upright is a beauty!
She is, that’s why I had second thoughts about selling her and killed the listing on Reverb.
She stays home, love it!
I actually went and looked at your EUB, and then I felt bad because my newest family member isn’t even home yet, 

. I’m good with two 

I just noticed @Hondo shared his site here… Gibson 5 string available.
Thanks!
I also have a Rumble 100 available, though local pickup in Phoenix for that one. Shipping is just too much to make it worthwhile.
I sold my Rumble 100 to someone in Texas and charged $75 shipping. It only cost me $60 to ship it from Phoenix, so I came out ahead.
IMO, listing with “local pickup only” drastically limits your market.
I took it, in its original packaging, to all three of USPS, FedEx, and UPS, and the cheapest price was $125. I don’t know what the difference is, but they seemed intent on screwing me on it.
Reverb give a much better price when you create the shipping label from their site.
I am loving the deals places like Reverb have with shippers.
Mercari’s is awesome for me - half price, and bidirectionally anonymous - neither you nor the buyer/seller ever learn each others identity or address.
Thanks! I didn’t realize that lol. I’ll have to Re-list it.
Look at what other people are asking for shipping so you’re in line with the competition. One thing I learned is that it’s better to sell your item at a lower price and ask more for shipping, since Reverb doesn’t include the shipping when calculating your fee.
I used to sell on ebay lol. I’m familiar, but it’s great info for everyone. Thanks
Let me know if you want to try out the Gibson EB-5 5-string
Save ya a fair amount 
Seventeen people watching my Warwick, but no one buying because of the pandemic. It’s really hurt the market for expensive items here.

There’s one bass I am tempted by with 40 people watching it and no one buying. Frustrating. If I were in the market for another bass here it would be a fantastic time to buy.
