MXR M288 Bass Octave Deluxe - blue lights don't work

[peledog]

My MXR Octave Deluxe is relatively new - at a gig a couple nights ago, the lights didn't turn on, both the main pedal switch and the mids boost. The pedal works - the effect is fine, but the lights don't go on, so I can't tell on stage if the pedal is on or not.

Anyone else have this issue? Anyone know what it might be? I've never had this happen with any pedal before.

Thanks!

I remember reading about this issue with this pedal here not that long ago, but can't find it with the search function. Probably was a post inside a thread, instead of a dedicated thread.

I remember the discussion going around pedal powering. I had this issue with phantom powering a DI from a console and found out the console's phantom power was enough to make the pedal work, but not enough to light it up.

Sounds a bit basic, but could that be your problem ?

EDIT: of course, there's always the "defective unit" possibility.

My blue light wouldn't turn off. But it works fine otherwise.

I had that problem recently when I added a few more pedals with my one spot. Seemed it didn't get enough voltage so I had to re power everything. Now its happy.

Interesting - perhaps the battery is running low? Not using phantom power, just a plain ol' 9V battery.

It's the only pedal I used at the moment, so it's not in a chain. I'm going to try with the AC adapter and see if that changes anything.

I appreciate the responses.

Using the AC adapter did nothing. I used it last week at a gig and it works just fine, it's just that the lights still don't go on. I'm off to the MXR/Dunlop site to see if they may have some insight.

I had the same symptoms with an Akai Unibass. I looked inside, and it was an easy-to-repair cold solder joint.

MXR has a phenomenal warranty. I used cheap jacks once that broke off in my BOD and they were gonna send me a new one for free, even after I told them it was my fault. Ended up fixing it myself but still give props to there c.s.
