I'd had a Samson wireless system for over 10 years where the transmitter used a AAA battery. Lately, battery capacity in the old unit was deteriorating. A new battery was barely lasting more than a set. My signal would drop to a whisper suddenly until I changed batteries. And I had to keep a spare cable handy as the likelihood of battery failure during a show increased.
I switched to the SonicSphere for my latest gig and got great results! Battery lasted through setup, soundcheck, elapsed time between first opener's set and ours, and our full set. The sound was every bit as good as when plugged into the amp via cable. Bonus: SonicSphere frees up plenty of space on my pedalboard as well and doesn't make me use an extra wall wart adapter like the old wireless receiver did.
I'm just trying to get into the habit of charging the transmitter and receiver prior to the gig. So far, so good.
Store owner replied:
Thanks, Jason! Love hearing the SonikSphere made the whole gig simpler, reliable battery, great tone, and a little more breathing room on the pedalboard too.
I bought the cfg sonicsphere mostly because it was supposed to have good sound and ability to plug into narrow guitar input plugs , such as Stratocasters. I have various electric guitars and a few electric Ibanez bass guitars SDgr series which have a narrow plug tunnel ( like stratocasters). I chose the sonicsphere over AKG especially due to that specific tunnel shape matter… when i connected the sonicshere to the bass guitars it turned out that the sound is indeed great but: battery holds only for 5 hours… and most importantly the transmitter can not completely plug into the Ibanes bass guitar tunnel. And i have to use special extenders that i had to find in shopping and turned out to be quite rare. See the three pics i attached. It shows the shoulders of the transmitter stuck before the end of plugging and how the short extender solves it… this i must say was a disappointment since the transmitter now is bold out of the guitar body and is swinging left and right while making some (amplified) crisp noise sound due to its movement… which i then had to support with a small velcro piece… very not elegant construct… so. Take it into account. And i hope that a future version transmitter will have narrow enough shoulders to totally entar and plug into the Ibanez basses Terriffic SDgr series…
All the best. Oded Meyron
Store owner replied:
Thanks for the detailed feedback, Oded, glad the sound delivers,
Please consider grabbing the Air-Pocket, which was made exactly to solve issues like that one
https://www.cablefreeguitar.com/collections/cfg-accessories-essentials/products/air-pocket (make sure the grab the straight one)
This little amp seems to have taken a long trip to get to me. Apparently from Florida to New York or New Jersey, and then to Alabama. So it took a few extra days to get here.
So it got here and I powered it up and I was stunned. This little amp is amazing. And it takes up so little space. It's plenty loud enough and does really good at a low volume. I am seriously impressed. It's very user friendly. It will be used a lot.
Store owner replied:
Thanks, John! Sounds like the TuneBomb took the scenic route, but we're stoked it was worth the wait and is already earning its spot in your setup.
Store owner replied:
Thanks, Edwin! Glad the ZERO-G Pro is keeping things comfortable while you play
I bought one and liked it so much I bought another one for my second bass. I have three basses on stage and am going to order a third one too. I will be using these straps exclusively from now on. Thank you.
Store owner replied:
Thanks Rhett, that’s a huge compliment, we’re stoked the Zero-Gravity strap is hitting the mark!
I ordered both the lightning bolt zero gravity strap and the Strap Sure locking strap locks at the same time. I love both of them. They are in heavy rotation during both practices and jam sessions.
My only complaint with the Strap Sure system is that I have three different Zero Gravity straps that I use and I only have the strap pieces for one of them. So if I change straps I have to remove them from the strap they are currently attached to in order to the locking mechanism or just use the strap without them. I want to order the parts for my other two straps only. I don’t need the strap locks that attach to my bass because I only have one instrument. Still I am going to make certain that I have extra parts since I’m planning on buying a second bass.
These straps (I have 3 of them) and strap locks are comfortable and secure and I highly recommend them to everyone who plays any type of guitar.
Store owner replied:
Love hearing all three straps are getting plenty of play! And that’s great feedback on offering the StrapSure strap-side pieces separately, we’ll definitely pass that along to the team. 🙌
I am impressed with the sound out of this little amp - all my basses sound great through it - the convenience to practice without hooking all my normal gear is really nice too.
Store owner replied:
Jim, love hearing all your basses sound great through the TuneBomb, that grab-and-play convenience is exactly what we built it for!
Using it outside when I have my tortoises walking around the yard...or when Im in my living room, not wanting to go upstairs to my music room...sounds and works great
Store owner replied:
Thanks, Darren! Love that the TuneBomb is getting yard time with the tortoises and living room duty too, glad it’s sounding great wherever you play.
Store owner replied:
Thanks, Jack, that’s exactly the kind of weight relief we love to hear about, glad the Zero-Gravity strap is doing its job!
I just absolutely love this strap. Just like my first Zero Gravity guitar strap, it’s extremely comfortable. The length is easy to adjust, and it just seems to be so well made. The Zero Gravity straps are the most comfortable straps I have ever worn, and they look so good with my bass. I love them so much that I ordered a third strap along with a set of strap locks. As long as CFG keeps selling them I will keep buying them.
Store owner replied:
Jessica, we love hearing that your Zero-Gravity straps keep your bass looking great and feeling comfortable, thanks for being such an awesome part of the CFG family!
It was simple to use, great range and felt good to cut the cable 😊
Store owner replied:
Thanks, Russell, glad the Zero-Gravity strap takes the load off your shoulder and makes that doubleneck feel easier to play!
I have several of these straps. They are all I will use now. So comfortable, I’m able to carry my heaviest basses throughout shows! Highly recommend these straps!
Store owner replied:
Thanks, Mark, it means a lot that Zero-Gravity is your go-to for keeping even your heaviest basses comfortable through a full show!
I have an off shaped bass and this stand works for it perfectly! Couldn’t be better!!
Store owner replied:
Thanks, Mark, glad the BunnyNest is a perfect fit for your uniquely shaped bass!
It's pretty great. It fits in my guitar hard case. So convenient for travel. Loud enough. Love the effects and drum machine. Wireless is where it's at!
Store owner replied:
Love hearing that, Keith, a travel-ready amp with wireless freedom, great effects, and a drum machine is exactly what TuneBomb is all about!
Upon receiving my straps, I had to make some adjustments. For me the shortest length was a little too long. I shorten the length my self (see photos). I used my new strap this past Sunday for one hour of worship service playing. ( See Youtube Video Link)

(Fast forward to about 9:40)
For me the strap did not feel as comfortable as my original strap. This is just my first assessment so please keep this in mind. I would also like to suggest designing some way to attach a guitar transmitter pack to the strap. Not every musician uses the one you sell. High-end systems are the one I am aware of that are being used by touring artists.
Let me know your thoughts and/or feedback.
Thanks in advance.

Store owner replied:
Don, thanks for the thoughtful feedback and for giving the strap a real-world test, we appreciate the notes on fit, comfort, and especially the transmitter-pack attachment idea as we keep improving the design.
Store owner replied:
Thank you, AT, we appreciate you choosing the SonikSphere!
It works really well for nearly every guitar/bass that I have. The only one I had an issue with (and it still worked for the lost part) was my Fender Jazz bass because it is a little offset at the bottom, so it leans a little in the stand. Other than that, it is an awesome product that I would recommend.
Store owner replied:
Thanks, Lindsay! Glad the BunnyNest works well across your collection, and we appreciate the helpful note about the Jazz Bass fit.
Love it.. all my other equipment is getting Dusty.
Store owner replied:
Love hearing that, Earle, sounds like the TuneBomb has officially taken over practice duty!
This is my 2nd one of these straps I bought so that I could have one for each of my basses. Most comfortable straps ever. I love them. This is coming from an old guy with a bad back that still loves to play music!
Store owner replied:
That’s awesome Alan, love hearing it’s got your back while you keep playing! Appreciate you rocking two of them
The Tune Bomb practice amplifier is loaded with features and is perfect for my Kala Baritone ukulele. The Bluetooth lets me practice with songs from my iphone - great feature. Put a little delay or reverb for an even better hall sound IMO.
For my Kala bass the output volume is weaker than my Blackstar Bass amp (with added speaker). I play bass for Southern Strings Mountain Music out of Northwest Arkansas. There are some 60’s songs we play that are nicely enhaced, with the delay or reverb. Makes for a nice sound variety between songs.
Store owner replied:
Rick, love hearing TuneBomb adding some extra color to your Kala baritone and those ’60s tunes, and we appreciate the honest note on the bass output too!
It was easy to use, just installed on my mic and pa and turned it on. They went into sink right away. I turned them off during breaks. The only problem I have with them is I read you can’t replace the battery in them when they go bad.
Store owner replied:
Thanks, Richard, stoked the Zero-Gravity Strap kept things comfortable through the show!
I was most impressed with the sound quality with and without effects, and the effects quality is also nice. I find myself playing more right now, and that’s a good thing! Awesome little jam machine that shins fantastic!
Store owner replied:
That’s awesome to hear Alan, that’s exactly what it’s all about!
I have tried three different bass guitar straps in the last few months, including this one, a nylon strap, and a different manufacturer’s padded strap,
Kind of like Goldilocks, the nylon strap is pretty but it slides around easily and it concentrates all of the weight in one area between my neck and shoulder.
The other manufacturer’s padded strap is comfortable but very very stiff and is difficult to attach to my bass.
But, my Zero Gravity strap is “just right.” I like the fit, and I love the comfort. The other padded strap is not even close compared to the Zero Gravity strap. I can’t say that my bass feels weightless, but it most definitely feels lighter because of the weight being spread out more evenly across my left shoulder (which is extremely important to me since I have an artificial left shoulder and a rotator cuff that I destroyed in an accident several years ago) and gets the strap off of my neck. There’s really no comparison between the two straps. The zero gravity strap is just better in every metric that matters. I love it so much that I have just ordered another one in a different pattern.
I highly recommend the Zero Gravity Straps for every bass player, especially those who use extremely heavy bass guitars. They work great on lighter basses but are almost essential for heavier ones.
Store owner replied:
Thank you Jessica!
we’re thrilled the Zero-Gravity strap gives your shoulder real relief, thanks for ordering another and sharing such a thoughtful recommendation!
Store owner replied:
Love hearing that, Peter, two straps in and still going strong!
About 15 years ago I fell and shattered my left shoulder and completely destroyed the rotator cuff. Even though I now have an artificial shoulder on my left hand side, it still hurts after about 20-30 minutes of holding my bass. I have tried several different bass guitar straps both wide and padded, and have not been successful in finding one that is both comfortable and strong enough to hold my bass. One of the straps even gave way causing me to almost drop my bass from a height of about three feet which could have severely damaged my instrument.
Then I found the CFG ZERO GRAVITY guitar strap while looking for other things on the website. I was skeptical about the claims being made about the strap, but I tried one anyway without expecting much from it. I ordered the musical notes Zero Gravity Strap and received it within a few days. Long story short, I now use it daily for practice, rehearsals and jam sessions as well as gigging. I love this thing. It is comfortable and sturdy so I don’t need to worry about it giving way causing my bass to fall.
I highly recommend this Zero Gravity Strap for anyone, especially those who need the comfort of a padded guitar strap because of arthritis or otherwise damaged shoulder. Well done CFG!
Store owner replied:
Thanks, Bernard, we’re glad the little TuneBomb is making a big impression!
The 2.5 inch strap is more comfortable than the wider one. I have used a leather strap for a long time and it is the most comfortable. I will stay with the leather strap.
Store owner replied:
Thanks, Michael, we’re thrilled the Zero-Gravity strap is the most comfortable one you’ve ever owned!
Thats means a lot to us!
I bought one to use with my guitars and then I also bought a second one to use with my aerophone (plays like a saxophone, but it’ll sound like 128 different instruments). There’s no delay and they’re very easy to set up. Plus, it keeps the stage clean.
Store owner replied:
Thanks, Kenneth, we love that NEXUS is keeping both your guitars and aerophone delay-free, easy to set up, and the stage nice and clean!
Awesome little practice amp. Great tones and features. This is my second one. First one fell off a short coffee table onto carpet and the input jack broke. My fault but be aware it's plastic and very fragile. The fact that I bought another one tells you all you need to know.
