FIX: Alesis Q2: First Made Strange Sounds, Then “Bad Program” Issue (QuadraVerb 2 Battery)

So I’ve had a Q2 since the Nineties and I like some of it’s effects.  But a while back when I wanted to use it for a Delay effect, it was acting funny.  Essentially the thing sounded like high-depth Chorus all the time!

So today, as I’m getting ready to work on a big project, I decided to look into this more.  Does it need to be cleaned inside?  I turned it on and it seemed that the Factory Preset Programs were fine, but now when going to create a User Program, the names of the Programs were all gibberish-y and when clicking the scroll wheel to “Select,” the name of the Program would just say “Bad Program”




“Bad Program”


So after a lot of Googling I finally found this. Turns out the problem is a dead battery soldered to the circuit board inside.

You can see it here, in the bottom right of the picture.  It’s a Panasonic BR-2325, a 3 Volt Battery with solder terminals on it. You can get them for a few bucks online, but I’m too impatient and resent shipping fees.


I replaced mine with a CR2025, a similar 3V coin battery that I had mistakenly purchased to replace a Mac Front-row remote.

But what to do about the missing Solder-leads?  It’s probably not good to cook a battery with a soldering iron, so I improvised a battery holder with two pennies.

Here’s the pennies with leads soldered to them


Next I put the battery between them. and taped it all together… I taped more than in this picture because I wanted to be sure there was very little possibility of shorting out inside the unit. I left my leads about 6 inches long so I’d have some slack to work with when soldering.



Next I desoldered the old dead battery and soldered in the leads from my DIY battery pack


Next, I gathered up the slack and taped the whole thing down onto the circuit board so it would rattle around inside the unit (while rocking out to tap tempo delay)





Finally, I  had to do a “Total Reset” of the unit, which unfortunately will delete your stored programs.  But I don’t think would have been stored anyhow, without the battery.  Not sure about that.

Total Reset:
A more drastic version of re-initializing the QuadraVerb 2 will erase all User Programs, as well as resetting all Global parameters. Hold down [PROGRAM], [COMPARE], and [<BLOCK] (block-left) simultaneously while turning on the power.

Now my q2 works again!

  1. Hi ! very useful information, really thanks !

    My Q2 is working nice again but I dont have the user programs anymore.
    I have downloaded midi-ox and Qclick software but I cant find the sysex files to download to my Q2. In Alesis homepage there is only a mid file. Any suggestions?

  2. Mike,
    I have no idea. But those older units usually did do a data dump/restore via midi.

    Also, I think the user programs are all blank by default, so you hmay have lost them by replacing the battery. I think the battery enable the unit’s memory.

    But if you learn something, share it with us! Will make it easier for the next guy.

  3. Thanks – same thing happened to Q2. I bought a CR2032 coin battery holder and soldered into the Q2. Next time, I just need to swap out the battery.

  4. hello
    I am the owner of a Qadraverb Q2 and I would like to program it with shadows effects, but i lost my Qclick 1.01 program :-(
    Do you know where i could find it
    all my best regards from Paris

  5. Jean Pierre, if you have not resolved, write your email address and I’ll send you the program

    Hi Andrew
    First of all, I apologize for my English.
    You can ask me for any problem (hardware or software) related to Alesis Q2/Q20. For some years I have been interested (for hobby) of their repair and their sale, and yet now I have someone too much on my shelves. I am a fan of Shadows and Hank Marvin, and only with Q2 or Q20 I managed to get closer to those sounds.
    As you asked me, I attach the link where you can download the software “QClick” but it only works with Windows XP. If you tell me what you exactly want to do, I could help you more.
    I cordially greet you from Italy, Giorgio!qM4SmBib!X8d5nY7jXV60eXG9Fm25PA

  7. Hi Giorgio, I told Andrew by email that my Q2 has the Winbond chips that run the battery dead in a short time. I’d like to make the modifications suggested in this post but am uncertain about the hazards of de-soldering the battery. qClick should give me enough functionality that I might not want to risk it.

    Regarding qClick, I owe you both an apology for putting you to the trouble. On an old hard drive I found a file named “qClick(portable).zip” and it turned out to be the elusive version 1.0.1. I’m leaving a link to that as well as the Registration number that will keep it working beyond 30 days.

    Thank you Andrew and Giorgio for your efforts,

  8. Great!
    This is definitely the latest version, and it works great on my windows 7 64bit
    Thank you Mal
