EVH 5150 III 50 watt question

[JustSomeDude]

Guys, first post here, been lurking for a while...

So, I got my new EVH 50 watt head with the 2x12 cab this week. Rehearsed it Wed, gigged it last night. Great tones, I really love the sound of the thing. Only issue is, I am getting an insane amount of feedback any time I use channel 3. Is this normal? Did I get a lemon?

(Sorry in advance if this is old territory, I tried the search engine but it doesn't really clear things up)

Not sure if normal or this helps, but I have a 50 watt 5153 and matching 2x12 and was playing last night. Only played in bedroom but volume at 3 and no feedback. This was sitting maybe 3 feet from amp also.

No feedback on my EVH 50 watt on channel 3 either. Might be a problematic tube, or possibly extreme gain settings. How high are you running the gain? I don't ever need to run higher than 12 o clock for the gain on channel three.

What are you running in front of the amp (pedals/pickups)?

 

[JustSomeDude]

Gain was at 9 o'clock. As far as effects. I have an mxr chorus and phase 90 and boss tremolo and Dd3 and a HOF reverb in the loop. In front just aBoss pitch shifter, ep booster and a wampler paisley drive. All of my guitars produced feedback. Les Paul and SG with 57 classics, strat with Texas specials and tele with tex mex pickups.

Could be a microphonic preamp tube. V1

Was the feedback occurring even with the EP and Paisley off?

 

[JustSomeDude]

Yup, even with no effects on, wicked feedback. I reached out to EVH. Good to see it isn't a common problem. Hopefully they can remedy or I will exchange it with MF.

yeah, something must be up. I've only ever had feedback problems when a boost was engaged.
