Confused so forget my review but...

Okay man what happend was like all my guitar amps with my death metal distortion settings when hooked together with all the pedals and cords to any of my guitars(sounds fine) but i have the static in the background when not playing and it’s so loud sometimes, it becomes frustrating or i get a headache but i know there are static and grain sound silencers or dampeners or whatever so i got on AMAZON 🤘😈 to look for it to play my death metal from my soul bro. So i find this thing one here the inject box or whatever and i could have sworn that i saw it cancels out static and plus i can hook up more of my instruments to it like i could plug in like 3 guitars and a bass and a electronic drumset and a keyboard at once or something wild of the sort. But i gotta have some giant robot thing called a PA system for it to work cause directions for guitar were all like “oh blah blah gotta connect it to PA SYSTEM to the amplifier then the guitar to the amp sound system or something stupid like ugh now i have to get more cords everywhere like usual i feel like a lost Vietnam veteran in the jungle stuck in vines. So many vines. Anyway from the physically held point of view and overall appearance it looks like it can do what it says and it has a lot of directions so if i think I understand it then everyone can understand it. Satisfying weight to it, not too light which is good cause light typically feels weaker. Not too heavy cause thank god lol. Two different panels in one small portable system at avery good deal. Keeping it even though itll be couple years til i get the pa system crap. That is what happened. I wanted no static on my guitars. (Sad hold F to pay respect rip george bush did titanic)

Solid Performance, Excellent Price!

Grabbed a handful of these units to bolster up my recording kit this year. I got three single channels and two dual channel units. Set them up for the keyboard player (Dual Channel), bass, and guitar player DI's plus one from a DI output on a effects module that were all on stage and connected them into my snake running to the back of the venue. Crystal clear sound from all 4 units straight into a recording mixing console. I was impressed.Not one pop, hiss, crack or anything from these units all night. Even was able to adjust the pad setting on the guitar and bass to cut the signal a bit so I didn't have to use so much compression to keep the signal from clipping going to the recording. No telling how long these units will last, but for the price, who cares, just buy another one and move on.

Check out how these boxes sound on the Band's YouTube page @ GerrellTheBand to hear the sound coming from these units. Near studio quality.

Exceeded All Expectations!

I've recently resumed gigging out at open mic nights. At some venues, I was getting noise and/or other sound problems (like distortion) from some of my active acoustic pickups. I bought this mostly for the ground lift to eliminate the noise. The first time I used this, I was playing a vintage ES-150. WOW! Not only was the noise completely gone (including static from the 50 year old pots), but by tweaking the ATT, I got a more pure tone than I ever had before on that old guitar. I also tried my Michael Kelly Patriot and was very impressed with the tone I got out of it; both times w/o using either of my equalizers or any effects. Since then, I've used it at a number of other venues, and like another reviewer, use it before or in place of the house DI. This makes my boxes, new and old, sound far better. I'm going to buy its dual channel big brother for those rare occasions when I bring more than one guitar. Best Buy For The Money!

ships mostly as expected

This passive DI-box is a great little tool that provides attenuation to interface a line or instrument output with a balanced microphone input. Some notes on this box are that the 0db attenuation still has some attenuation. The -20db attenuation sounded funny, but that is probably because I used the same equipment for all attenuation settings. With each attenuation setting, I had to adjust the input volume accordingly. This device also has some ground lift switches that can prevent ground loops. All the devices that I tried this with did not have their own internal grounding, so I needed to have the ground come from the mixer. I did get some hum when I would touch the case, just like I did with other DI-boxes. This product worked very well for my needs.

Portable, works fine with active guitar pickup

I bought this because my band's primary PA mixer doesn't have high-impedance inputs for a guitar pickup, and I don't always want to bring my submixer for quick-change gigs. So, a small, cheap DI box seemed like a good solution. The PDC21 is a no-frills device. It converts a 1/4" instrument cable (high Z) to a balanced/unbalanced 1/4" or XLR (low Z) signal. It does a fine job. I don't notice it coloring the sound (i.e., it's not changing the balance of frequencies transmitted) although it does lower the volume somewhat. That's to be expected in a passive DI box, and it doesn't bother me. I'm using it with an LR Baggs M1A active soundhole pickup. The M1A spits out a fairly hot signal, and I don't have any problem with the signal loss associated with the PDC21. If I were using a passive pickup in my guitar, the results might be different. Bottom line: it's small, fairly light, seems durable, and it does a good job converting my active guitar signal to the XLR inputs our PA mixer requires. It does everything I wanted, and the price was right. I see no reason to go shopping for a more expensive one.

Fantastic Direct Box

I used to have a hum from my guitar all the time. I have a mixer for all the instruments in my garage band and was told this product would eliminate that problem. Guess what it did. I am well pleased with this product and the price is amazing. Would highly recommend.

Good for a passive DI -- amazing for the price

I just ordered a second one. I'm using this to eliminate ground hum by isolating laptop outputs, and also in a live performance setting with bass (line out from pre) and keyboards. There is some signal loss as compared to active DI boxes, so it's not a first choice for going direct with low-output instruments (passive electric bass etc), but with active drive it sounds good (inaudible), I haven't been able to overdrive it to distortion, and of course it doesn't need batteries or phantom power--great when you don't know what to expect from house sound. At the current price (under $20) it's unbeatable. [update] I've noticed that it picks up hum from the Silver Dragon's giant wall wart power supply. I believe this is inductive coupling between the two, so will probably be an issue with other passive (transformer-coupled) DI boxes, and is more likely a problem with the wall wart generating nasty huge magnetic fields. :) Still, it happened so I'm mentioning it here. Separating them by a foot or two fixes the problem. I haven't broken any of the switches.

Price to performance ratio can't be beaten

Works as advertised. Price to performance ratio can't be beaten. I really can't fathom the negative reviews. Faulty product, or misunderstanding about how to use it properly? I couldn't be happier, as a musician who uses this box as a PA/recording interface for my P-Bass. Low noise/low distortion. I'll repeat, works as advertised.

Best bang for your buck in having quality live sound

I've been using these for about 3 months now. I'm new to live sound, and just learned about direct boxes. These are essential for ensuring that your instruments produce minimal interference and noise. I currently have 2 units and input the following instruments: acoustic/electric guitar, electric viola, electric piano, electronic drum set. The direct boxes output to a snake, which in turn outputs to the mixer. Previously, we were plugging our instruments directly into the snake which resulted in constant noise and interference issues. This particular model is admittedly my only experience with direct boxes. But so far, I can say it has cleaned up all the noise issues we've had from our acoustic/electric instruments. It has a sturdy, durable build. And it is dirt cheap compared to other models. It also has a built-in attenuator if a particular instrument is coming in too hot, and a ground lift switch to ensure you have plenty of control for your setup. I can't speak much for longevity, but I will definitely update this review if any of my units fail on me.
