Hi i was wondering if anyone knew if I could run one H9 in the effects loop of an HX stomp? And is it ok at line level?
Yes.
Also wondering how it works with having multiple units, Does the Bluetooth connection to my laptop automatically sync both and put all the algorithms i purchsed on both? I didnt but the second one yey but I hope to
Yes. You can connect 2 H9s to your laptop and control both of them there. Some users have issue with connecting to multiple H9s via Bluetooth on Macs. You may also use USB to connect if that happens. All algorithms you purchased for the first H9 will be synced with the second one.
