Hi all – I just got a 4 knob blue face DMM (with squelch but no modulation) and it sounds great – but it doesn’t go 100% wet like my 5 knob 90’s DMM. Is that normal for these ones?
I haven’t played an original so I can’t give a definitive answer but it should give very close to 100% wet, a little bit of dry bleed might be expected as it’s a passive blend although so is the 5 knob.
It’s very possible that it needs a couple of electrolytics replacing and re-biasing at this point in its life.
