JamStack Attachable Guitar Amplifier

The JamStack is an attachable guitar amplifier that connects effortlessly within seconds to the base of your electric guitar. It is lightweight, sounds incredible, and connects to any smartphone to open up an unlimited world of effects. Whether you’re jamming in the park or practicing in your apartment you can take the JamStack anywhere and everywhere. JamStack’s 10-watt speaker sounds great at high and low volume. You can sound as good practicing at night with low volume as you would jamming alongside other instruments. Traditional guitar amplifiers can’t handle multiple frequencies at once. Also, the backing track drops out of the mix when you start to play. With the JamStack’s drivers, it sounds like you’re right inside the song, playing alongside your favorite musicians.

A central feature of the promotion of this product is how loud it is. It isn't. If you have a guitar with double coil pickups, the volume is ok on the passthrough setting but there is volume loss and sound dropout when you use the amps.


Don't even bother considering this if your guitar has single coil pickups. On passthrough setting, the sound sounds like it is coming out of a soup can. Its performance with amps is pathetic. The tests that led to these results were done in conjunction with guitar techs at a guitar store.


And for strike three, the company has horrible customer support. It can take 7-10 days to get a reply, or never. They refuse to acknowledge the single coil/double coil problem even though they must have known this to be true from their own testing.

We appreciate your feedback, Ian!

Never got the product and service is HORRIBLE!

Ugh, thank you for letting us know, Joe!

Ordered in September- Official Website said they were shipping products in September- Never Arrived. October 26th was told that they were shipping in 3-4 working days - Never Arrived. Oct 29th was told that they would arrive by Nov 7th - NEVER ARRIVED. Nov 27 was told last units would ship on Dec 5th - NEVER ARRIVED. Dec 11th was told it would arrive by the end of the week - HAS NOT ARRIVED!!!😡

So sorry to hear that, Sarah! 😩


This says I can buy one for $145. But when I go to the link it says it's $249. I would like the $145. Price. What gives?

Gadget Flow Editor
Hi Deb, Apologies for the price difference. This is an old listing and the new pre-order price is $259. We've updated the detail from our end. Sorry again!😣
Don't buy it.....they don't even have a product. I bought this immediately after they appeared on Dragons Den (Canada). After a series of lies and missed promised deadlines, they still don't have a product to sell. It's been almost a year.....Money has gone.
Oh no! I'm guessing you've already contacted the seller directly, Jason?

When and where can I buy this?
