The extra machinery for each amp is around 1000eur or usd so that is a big investment. And then add the cost for each amp of course.
I think this service is cheaper than other reamping services where there is a technician operating the amp. In this system you don’t have to interact with another person and you can reamp at any time you want. Also the turnaround time is much shorter now when you batch job all tracks in one run if you want the same sounds on many tracks. You can also start to dial in another amp while the first amp is running the batch jobs.
It’s pretty cool actually.
The price I have chosen is 1€ per minute. And that is calculated very precisely.
