Positive Grid US

Disappointing due to no support to allow download of presonus. Also website and instructions for Riff could be better process and more clear. Location of serial number is not evident

I will amend this review if my issue is resolved to my satisfaction.

Non working Spark 40.

i NEVER RECEIVED IT !!!!!!!!!

Horrible customer service. Still haven’t received amp weeks later and the customer service told me to double check around my house for the delivery. Lol. I work from home and get all deliveries hand given to me since I am home. Same for this order, no amp, no help from customer service. Check the BBB on this company before you make a mistake and buy from them
