Blues Deluxe Reissue. Weak Reverb?

    I've just bought a Blues Deluxe, the amp sounds great and I love it.
    I've just a question about the Reverb: Do you think it's normal the Reverb is really "light" or "weak" ? I mean that the Reverb starts to give a nice, deep sound only if I turn the Knob over 7 or 8, so if I want a really "full reverbered" sound I have to turn the knob around 12 (and even at 12 it's not a Pulp Fiction sound, but just a nice, warm but not too strong, reverb).
    I hope to explain me correctly, I'm not sayng that Reverb doesn't work (the sound is nice), but only that Reverb is not strong as I supposed to be.
    Fo example, on my other amp, a Blues Junior the Reverb is less warm and less good, but I if I turn the knob at 7, the sound is totally reverbered....
    So I'm wondering if it's simply a matter of different kind of reverb or if it could be an issue of the amp.
    Thanks. RS

    Might need a new tube. The reverb should be just as strong as the BJr.

    @Rusty Silver ,

    The reverb on the Blues Deluxe is a TL072 OP-amp, no tubes.

    This circuit can be defective, but first I would search somewhere else :

    1 - check the reverb tank itself. On it, there is a reference number. It should be 4EB2C1B or 4EB3C1B to be the convenient type.

    2 - check the DCR of input and output of the reverb tank. Input = drive = circa 58 ohms, Output = recovery = circa 200 ohms, springs being totally immobile.

    3 - check if the reverb is connected in the right sense, not input and output reversed cables. Try to reverse and test if it sounds better, no danger here.

    4 - tight the CINCH connectors on the reverb tank.

    5 - check if the springs are fully free, not more or less hindered by the tank installation.

    With all this, you will have an idea about your reverb issue, I think...

    Let us know ! ;)

    Thanks for your suggestions... I'm going to check... Anyway is there on this forum someone who owns this amp? I'd like to listen other users opinion...

    Unfortunately, I do not have this amp, but I repaired /serviced at least one dozen of them... ;)

    It could be something as simple as a dirty or corroded connector to or from the reverb tank.

    Well, thanks guys. I've just opened a similar discussion on an Italian guitar forum. It looks that's simply no issue or defect. Just the reverb of this amp is nice and warm but a little weak. Two guys wrote me that have the same amp (latest model) and they have to put reverb on 12 to hear real reverb sound.

    The reverb on my Blues Jr. is very weak. I had the reverb chip replaced but it is still very weak. Now I use a TC Hall of fame 2.0 for reverb on it and everything else. Perhaps the problem is with the way the reverb tank is mounted?

    I had a first gen Blues Deluxe in the '90s and the reverb was very strong, almost surfy. Also i could swear it was tube driven as i had a problem with a microphonic tube when the reverb was cranked. Maybe my memory is playing tricks on me.

    The original Blues Deluxe had a tube driven Reverb, the actual model has a solid state driven Reverb

    Hi Rusty,
    I have the same amp, and I'm here for the same reason.
    I love my blues deluxe, great pedal platform as well, but reverb is tooooo weak!!!
    I made some test swapping the tank with one taken from a 90's peavy bandit (totally compatible tank model, according to online documentation).
    The tank on the bandit sound super surfy, with lot of drips on top even at low volume, but in the fender this not change the results.
    I was in a store to test a brand new model, I noticed a good amount of 'verb, more than I can get at home... It's true.
    I back to home and test my amp at very high volume, just before limit of tube breakup, I have a loadbox and I can test it with an IR Loader sporting exactly same amp speaker and cab combination :D
    The result is: at high volume there is enough /verb for a shy, almost decent surf tone. I cant say if the newer or older model sport a deeper reverb, but a lot people suffer the same lack.
    Here a video of a guy that fix the problem with a new tank model.
    One of these days a will try to do it, if I'll get a good result you can come to hear it, I'm in Rome!
