I'm absolutely blown away at the tones I get from this new Maz 8. If I had saved all the money I spent on pedals all these years and just bought one of these... anyway...
My variable boost knob doesn't seem to vary the boost. I can't tell a difference when I turn the knob on the pedal. Is that normal?

I don't have the Maz 8, but I can tell you that on my Zlux and my Remedy, when you step on the boost it GETS noticeably louder, especially at gig volume.

No. That’s not normal. The purpose of the knob is to vary the boost.

That's not normal. But if you already have the amp totally maxed out headroom wise, then it might not be as noticeable. If it isn't doing anything at lower volume something is wrong with it.

Do you have a DVM?

If you are running you tone controls maxed then the pot on the EQ bypass switch will have little to no effect.

Is that a Digital Voltage Meter? I have one of those.

Make sure your battery is in good shape in your meter first. It'll probably have a 'batt' icon on the display.You can find out if your variable boost knob is working by setting the DVM to read ohms (if it is not an autoranging meter, put it on high resistance, you'll be reading up to 500K ohms), put the probes on the variable boost control's plug at the tip and barrel (polarity doesn't matter here), and read the resistance. If the switch is in one position it's going to read something like 0.5 ohms, pretty much a dead short, and you won't see any difference as you rotate the control. That's okay. Press the switch and try again. You should read around 500K ohms (that's 500,000 ohms) to near zero as you sweep the control from one extreme to the other. I'm pretty sure Doc uses 500K pots in the variables. It's possible that there is a 250K in there but I doubt it. At any rate, the idea is to see if you sweep from near 0 ohms to 250K or 500K ohms. If you see the change happening then you know your footswitch is ok. If you don't see a change then you've either got a loose connection, bad plug, broken wire, or a bad potentiometer in the footswitch.

I don't know if my cheap multimeter is giving me good readings, but it appears to have 1k ohm thru the cable and doesn't vary when I turn the knob.

What happens when you press the switch on the box? Does it still read 1K ohm? It should drop to 2 or 3 ohms. Mine reads about 2 ohms with the switch closed, and 243K ohms when the switch is pressed to the other mode and the knob is all the way turned up. If I turn it all the way down I read around 3 ohms. Bear in mind that mine reads 243K because it has a 250K ohm pot in it. Yours probably has a 500K ohm pot if it's factory made, and so it should be reading from 2 or 3 ohms to close to 500K ohms. I assume you're measuring from the tip to the shaft of the plug, right?

I wasn't reading it right. The 1 is what it reads when I put the leads together or through the pedal when it's switched off. When I switch the pedal on to bypass the eq, the meter reads open circuit regardless of knob position. I'm going to find a better meter.

I decided to ask Dr Z repair if there was another test I could do to figure this out, and they just sent me a new footswitch. The new one works great, so apparently the original one was defective. Thanks for the input.
