My new HBE module is unusable with the gain past noon. I get a ton of squealing feedback then. In comparison I also have the SLO and BE and both those modules are quiet even with gain at 3 o'clock.
I replaced the pre-amp tubes in the HBE...no change. Probably needs to be sent back to Synergy.
Anyone else experience this with a high gain module?
