I have a few Z amps and have always used open back cabinets. Tomorrow I have a gig at a place where the band sets up is kind of like a small hardwood bandshell, but wraps around the sides quite a ways. It gets pretty loud with a lot of frequencies getting cancelled out in "the Wigwam" as we call it. I'm thinking if I used a closed back cabinet it would help keep the sound from shooting out the back and swirling around, thus reducing stage volume and frequency cancellations. Given the choices below, which would you do closed back? I have a large variety of 12" speakers to use, so feel free to suggest the actual speaker pairing as well.
Therapy Z28 Maz 18 Cure (It is in a combo now, but I have a head cab for it also)

I’ve run my Therapy into a closed back Z 2 x10 with great results. So I’d say Therapy, but I’m sure they all would be great.

Very disappointing gig last night. We played a place that we've played before and never had an issue with power. I setup the Therapy and strummed, ran a couple scales etc to make sure everything was working. I got a very harsh, terrible distortion on a few low notes. I tried a different guitar and plugged a different cable straight in and the unpleasantness was still there. So, I swapped out the Therapy for the Z28, including different cab. Distortion was still there. The other guitar player asked if I was getting crappy, farty sounds and I said yes. He was too. I muddled through the night. I've had a couple power conditioners before, but haven't used one for a few years because I hadn't needed one. This evening I ordered a Tripp Line Conditioner. I've gigged for several decades, but feel like such a rookie...

Man, sorry to hear that, my guess is it won’t happen again but it does leave you frustrated to say the least.

My experience is that that is usually caused by a problem with the line voltage and most power conditioners won't help that unless they also regulate the voltage and those are very expensive.

Expensive and heavy. The $50 variac and a voltmeter might not be a bad idea.

Interesting. This thread sent me off down a rabbit hole! It looks like a ferroresonant constant voltage transformer. Hammond makes this: www.hammondmfg.com/CVR.htmThey say it's not suitable for office use due to audible noise. I wonder how heavy it is, and if it's noisy in use? Hope it works out for you.

I didn't see a price on this. Just curious. One time many years ago I had a bad experience with voltage at a gig and I suppose that made me a little paranoid about it. I looked into voltage regulators and they were too expensive I thought. I had a variac that I used in my shop at home so I started carrying it to gigs. I wound up not needing it for over a year so so I quit that. Actually the only place I have had a problem is when we played outdoors and had to run off a generator. Those can be pretty iffy. I do take a variable isolation transformer to those gigs. The price on that Tripp Lite product is surprisingly reasonable. I would still have to think about regularly lugging around another piece of heavy gear.

You didn’t mention swapping speakers (your last variable). Could that be the culprit?
If the problem is low power at the wall, I’m not sure of a solution. If you’re getting over 117… try an amp preserver or a brown box. Pricier than a variac, but much more convenient.

Now that I have something that will probably work, I'm sure to never need it.

I ALWAYS use a Furman Power Factor Pro (the large brick model) at any venue that I'm playing at to protect my gear and to keep it sounding right (making exceptions for the room of course.)

just set up the Tripplite I bought, last night……………..all noise gone! However my amp(Jetta, it seemed to sound a bit thin, however, there was a huge increase in high-end and gain …………. I think that it’s likely the increase in gain and high end is giving me that perception, and I just need to adjust for it on the amp, and most likely in my case to Guitars tone in volume. I think it’s possible that my ear got used to the reduced high end and I compensated for it with the eq/tone/volume. I’m going to play it this evening. See if I have any changes and plan to give it a week to get accustomed to the changes. anyone else have this issue, or temporary issue like this? I may have a duplicate post on and old thread

Too bad you didn't have a meter to measure what was going on with the voltage.

The transformer took line voltage from 116 to 120
