...and about those MBPs...
Does anyone have any experience connecting non-GK products to one? I've used them with a GK Plex with success, but was pondering connecting a Line Out on a Phil Jones Bass Double Four Plus to my MBP112 for gits and shiggles.
Looks doable...
From the MBP112 Manual
Connecting your MBP to an MB Head: When connecting an MB head to an MBP cabinet, a cable with a male 1/4” Tip/Ring/Sleeve to a male XLR end must be used. Plug the 1/4” TRS into the Headphone/Line Out/Chain Out jack of the MB head and press the corresponding button to the 2 position, Line Out/ Chain Out.From the MB200 Manual
Headphone/line out/chain out: When switched, this output allows the user to send a direct (unbalanced) line out to devices with unbalanced inputs such as personal multitrack recorders. This connection requires a shielded patch cord. The Chain out allows the user to connect directly to a GK MBP powered extension cabinet. This connection is made with a balanced, tip, ring, sleeve to male XLR cable.I've got the appropriate cable, used from Plex to MBP with success.
I'm pretty sure @mmbongo tried connecting the Plex to various cabs and whatnot, or maybe he tried various preamps into MBPs - I can't remember.
