I have been waiting for a set of Basso since around mid August. When I e-mailed them a month or two ago Jan-Ole apologized for the long waiting time, he said that they had problems with producing strings during covid and they were not quite back to full speed yet. He told me to remind him about my order if I didn't hear from him again during December so I just sent him an e-mail last night to hear what the status is. Hopefully they will be ready soon.Is the wait time still very long for Tempera strings? I recall years ago that they wanted it to be a similar production pattern to Velvet but it seems like it is still very bespoke.
If you are interested in the strings I'd say just place an order now. It will take a while and you are not paying for anything now or committing to buying when they are ready.
