FDP Forum / Fender Amps: 1985 - Current / Reverb Strength for Fender Deluxe Reverb 65 Reissue


Pennsylvania, US

Hi everyone!

I have a question about the strength of reverb concerning a Fender Deluxe Reverb 65 Reissue.

I recently replaced all the GT tubes in the amplifier with the JJ Electronics 5AR4,6V6,12AT7, and 12AX7 tubes. I have bought the amp used about 3+ years ago and have never replaced anything on the amplifier since purchase until the tubes.

Nothing necessarily was wrong with the sound of the amp before or after tube replacement, but the strength of reverb definitely changed.

Before the reverb was extremely strong and would give a deep reverb as like a surf rock sound. I typically like the reverb around 3 or 4 since anything greater was too much in most applications I needed, but I liked having the option if needed.

Since tube replacement, the reverb is not as strong. It still works and sounds good, but the reverb set on 10 is similar to what 4 used to be.

I never played another Fender Deluxe Reverb to compare to and was hoping someone could tell me how the reverb on a stock Fender Deluxe Reverb sounds. Thanks in advance for your responses.

Try putting back the GT 12AT7 in V3. That's 3rd from the right as you look at the back of the amp. If that doesn't restore things, put the GT 12AX7 back in to V4. That should do it unless something else changed along the way.

Okay, I will try doing that tonight when I get home and see if that fixes it.

Thank you!

I tried what was recommended about replacing the JJ tubes with the GT 12AT7 in V3 and GT 12AX7 in V4 and nothing changed. I ended up putting all of the original tubes hoping that would fix it, but still a weak reverb.

I think that you should try moving/rotating each connector to and from the reverb pan to see if it's down to a poor connection. Changing tubes might just have upset this.

Just a thought but when the amp was laid down to change tubes the pan springs may have become tangles or unhooked

An inspection of the inside of the reverb pan is in order. tuninguitars is right. If a corner has come unhooked, the reverb can be seriously affected, or if a reverb spring has come off. Not uncommon problems.

I have had weak solder joints on tube pins let go when changing tubes and cause problems also I have found loose washers and nuts sliding around in amps that get trouble started,
