QuarterMaster QMX - 4

Excellent product. Compact. Quiet switching. Flip flop mode works great.

This is my second Quartermaster. I grabbed this one to go on a small board. I love these. Makes those old pedals true bypass and also gets rid of the annoying “pop.” The signal is stronger and it saves wear and tear on your pedals. Great product!

I purchased the QMX-4 to replace a Loop-Master 4-channel mechanical switch looper. The Loop-Master served me well over the past 3 years of giging (approx. 50+ gigs), but the switches didn't survive the COVID shutdown and neglect the past year and the switches started to fail. About 1 out of every 20 clicks on 2 of the 4 switches resulted in no sound until clicked again. So I've recently upgraded to the QMX-4. It dropped in with no issue. I am already using a Strymon Zuma PSU so the extra current QMX-4 needed was no issue. I love the soft touch footswitches and look forward to testing out it's reliability over the years to come. I did notice the QMX-4 is less noisy than the Loop-Master, I assume it might have to do with the isolated send and return jacks versus the loop-mater which are all gnded to the chassis.

Nice made my Pedal Tran Novo 18 build great. Love the ability to instantly change tones without having to have a large board or do alot of programing .

I just recieved my gigrig Quatermaster qmx 4. I have to say this is hands down the best loop switcher out there. My tone has never been better and I love the silent footswitchs. Plus the flip flop function is great!

First of all, I have spent several decades pushing effect switch buttons with my finger. My fingers are killing me! These button are like a dream to push with finger or feet, (if you have to use them). Secondly, it is beyond my understanding as to why pedal makers insist on, always on buffers. Put a switch in there! If I want a buffer, I will buy a stand alone good buffer. If you stack pedals, which if you have enough time and money, you will find the perfect pedal combination for your tone. But after about 3 always on buffers...that what predominates: ' always on buffer' sound. I have a chain of 6 stacked pedals. So even if there are 3 pedals on, I got 6 buffers! With Gig Rig, I switch off 3 pedals and I have three pedals and it sounds great. Further, II have 2 pairs of the same pedals. What sounds worse than 6 buffers on. Two buffers from the same vendor. So now, I push that switch in, on the jack field (Red LED), and I toggle between 2 pedals with different settings from the same manufacture. No more buffer overload.

This loop switcher works perfectly with no problems/issues, and can do exactly what you want/need it to do perfectly. Additionally, product is very well-made.

I've only been using this for a few weeks now, but I absolutely love this switcher pedal. I use loop 1 for my tuner and the rest of the loops for my different drive types. It was nice that it came with a plug to setup one loop specifically for a tuner loop. Really should have bought this sooner. No more dancing around to hit the right pedals on and off anymore. I even have the second loop setup for my always on drive (Wampler ego into Greer Lightspeed). I may have to order a second one for another pedalboard in the future.

This QMX-4 is exactly what I was looking for to switch between overdrives and distortions on my compact pedalboard. The build quality is immaculate and the product is very sturdy. I have already recommended this product to multiple people and will continue doing so. This product has also convinced me to order other GIGRIG products to complete my pedal board.
