ENGL Blackmore extreme squeal

Recommended Posts

Posted (edited)

Hi Everyone,

Bought a second hand ENGL Blackmore. ESP guitar with EMGs & an ISP Decimator. Played it three time with band rehearsing & I'm seeing the following get worse (was ok first time)...

1. Real loss of gain - it's a higg gain amp with active pickups & I'm needing to crank gain to 10 to get even a classic rock sound.
2. Screech/squeal - any sort of volume from guitar on high gain & I get this ear piercing screech. Basically unplayable. Not feedback - I can get 'real' feedback but going close to amp & then if I increase gain or volume the screech kicks on over the feedback.
3. Intermittent sort of interference on the tone.

Squeal only happens on high gain channel - also tried two guitars & same issue. Other guitar had passives.

Bought on Ebay & no return possible, so obviously need to get this fixed. Is it the tubes? Seller said it was a about 5 yr old (mint condition) but hardly played for about 2-3 yrs.

Cheers all

it sounds to me like a tube issue - tubes can become microphonic and, in cases of extreme gain, sometime cause acoustic feedback within the amp itself

your best bet would be to replace all of the tubes and, if that doesn't solve the problem, take it to an experienced tube amp repair person

Yes, it's a tube gone bad.

If he has a extra one, he could do one at a time to see which one it is.
