Fender ProTube Twin-Amp reverb feedback

[Mick]

Glad to hear you got the Twin fixed, Mick. You should post a pic or two of it sometime. With your photography skills, you could make it look sweet.

Thanks oldguy! I'll give it a try soon. I've actually been thinking about trying to recreate some of Fender's ad shots.

That sounds like a cool idea. I've always liked this one, even though it came out two yrs. before I was born................don't know if it's the dachsund or the raybans...................

Oh yeah, that's a good one!

I also like the “You Won’t Part With Yours Either” ad campaign photos by the late Bob Perine. Cool stuff!

Just recently picked up an old Peavey Deuce as it's the closest thing I have found to a Twin in my price range. Had the same issue described here. I pulled the reverb tank from my crappy 80s Fender Princeton Chorus and plugged it in, problem solved. Then I pulled the tank out of the deuce. It is clearly a new tank, so I was surprised to find that inside it there were blocks of light foam (think packaging for a retail product) in the center of the tank. Pulled those out and the issue was immediately resolved.

My theory here is that the blocks were acting the same way your finger does when you play the harmonic on a guitar string at the fifth, seventh, 12th (and so on) frets of a guitar.

Wish my Deuce were your Twin, but now that it doesn't feedback it is exactly what I was looking for.
