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
