Hello all, I wanted to test some reverb pedals tonight - and of course I wanna put 'em in the FX loop. I just connected the pedals with two 12" patch cables - and I was shocked: all the highs were gone and the sound was totally dark/ oompfy! I replaced the cables, replaced the pedal... Finally i found out that as soon as I plug a cable in the SEND socket on the MAZ (nothing in the RETURN) I loose the highs and get this bad sound. I never used the FX Loop before so I didn't notice that earlier. Any idea out there? I would really appreciate any help!!!

Did you try swapping the in and out cables. Maybe you're running it backward accidently.

Did you try swapping the in and out cables. Maybe you're running it backward accidently. I've double-checked it and even swapped in/out - same effect. As I said: as soon as a cable is in the SEND of the Loop the highs are gone.

The effects loop is passive, there is no signal boosting circuitry in the loop. Dr.Z it's told me that it's just there as a courtesy, but thats about it.
Any cable more than 3 ft from the send will result in a loss of highs. You'll notice that on most amps with an 'active loop' there is some sort of volume or loop gain, but on the maz there isn't. It's just there as a courtesy.
You could run a small 3ft cable to a signal booster like a Duncan or a Tube PRE and that will resolve the issue. I have a few TubePre's lying around and tried it and it worked like a charm.
But to be honest with you, Unlike most other amps, the MAZ can take having pedals infront of the amp such as reverb, delay etc... Just don't put your reverb or delay before your distortion.
Honestly, there was no benefit using the loop vs. putting the pedals infront of the amp. I have mine infront of the amp. Just ask any of the Kalhuna's or Z-Natics... they'll tell you the same thing.

If you're running the amp clean you can use delay and reverb into the front. If the preamp is cranked you won't like distorted reverb and delay. Just as an experiment i plugged a cord into my effects loop and it make no change in the amps volume or tone at all. I see a technician in your future...................

Billyguitar, you are correct about about cranking the amp. I find I have to turn down the saturation of delay or reverb when I lean on the pre-volume.
No need for a technician... The change is ever so slight... Dr.Z (in not so many words) said you have have to be really anal to hear the difference. I mean really slight... It's so faint, that a small tweak of the Hi Knob will correct it.
No need for a technician. Dr.Z already said, it's a passive loop.

Thanx a lot, guys - it's maybe the easiest to run the reverb in front of the amp (I do this with my delay anyway...). But apart from that: the loss of the highs is really critical, even with a 1ft. patch cable used... I will also try the use of a signal booster in the loop - just because I'm curious...
