basically, it's powering up, and when turned on you can hear it, but very quietly (when turned on, i hear nothing)

anyhoo, what's going on? and if i need to move the board dealie, how do i get it out?

Do you have the correct power supply the old hm-2’s used 12 volt and sounded weak / quiet if you used a 9 volt adapter.

If you plan on fixing/troubleshooting your pedals, you need at least two things. A digital multimeter and an audio probe (and of course a soldering iron). You will probably have to build an audio probe but it's easy and if you google it, you'll find how to build one.

You would use your audio probe to see where the signal dies/lowers. Print out a schematic and follow the signal through. I usually start at the input and outputs of the IC's using the IC's in the schematic to break the circuit down into sections. You'll probably have to check the IC's datasheets to find their in/out pins but they are pretty standard.

For us to say, "Oh, Q3 is bad" just by you telling us there is a problem isn't going to happen. It could be anything in there.

If you have no clue about anything I'm talking about, it's probably better to get someone to fix it. It's not one to start troubleshooting on. It's pretty packed in there.


If you are using a battery, make sure it's good. Make sure you are using a power supply that is meant for effects pedals and not some Radio Shack/generic thing.

I 2nd the audio probe...... but if u cannot figure it out with that I say just buy a used one as they are dirt cheap used
