Coolmusic BP40 40W Portable Acoustic Guitar Amplifier Battery Powered for Artists on the Go Built-in Bluetooth

The various lockdown has had some advantages in that it has given me a lot of time at home to learn things that I have always put off due to being too busy. I’ve been learning guitar for a few months now and although I’m not great, I’ve been looking for an amp to enhance the performance aspect. The electric sound can hide some playing mistakes with it's noise. I bought this one after finding it and thinking it looked perfect for my needs. It’s small enough to be easily transported if you’re looking to go out and about busking, while still having a great sound quality and an impressive battery life of about 7 hours. You can use it while plugged in to a mains output or from the built-in battery after it’s been fully charged (takes about 5 hours). It can also function as a speaker for your phone or microphone using Bluetooth or wired connection, but I primarily use it for my guitar. All the control knobs on the top function as expected and provide a good amount of customisation for your sound. Great value amplifier, perfect for at home or out and about use.

This is a fantastically useful little amp which currently is being used for at least 2 songs/hymns in church every week. Some of the best money that I have ever spent. Sound quality is excellent and it is plenty loud enough to do do our small outdoor meetings with 2 mics and guitar. Recharged after 2 months light use. Again, virtually PERFECT.My only criticism is that the BluTooth link is locked too loud with no facility to control the gain. Ergo, had to have my phone on only 1 blob and that was still a bit too loud. I have not yet looked very hard for a solution so... there may BE one.

The item arrived on time an was exceptionally well packaged. The instructions were fairly straightforward. It is much better than the amp I was previously using, which I have had for over fifteen years. Bass and treble controls for one input are very handy, and the Bluetooth is an additional extra that could be useful, also the small jack input, which although labelled as for phone use can in fact be used for anything that uses a small stereo jack. The output volume is pretty good for a small amp and so is the sound quality. it is also very light to handle and has a carrying handle to make things easier for transportation. The battery charges fairly quickly and appears to last well. The price was also very reasonable. I have used on three occasions so far and it appears to be up to the job.

Prompt delivery, well packaged, clear instructions. Already semi-charged - but hooked it up - really easy. Sound quality is good - I use with electo-acoustic guitar and Behringer mic - plenty sound for my care home performances. Reverb on channels is pretty good. I've also hooked a battery powered mixer with FX for my guitar - delay/chorus. I think I will get a stand to lift it off the ground. Next aim is to add backing tracks though bluetooth or USB. Excellent value for money.

We bought it for less than 2 years, now that the battery can't even last for one hour. Also when it turned it up the maximum like we do, for some reason lot of whitenoise. We are searching for another one now, don't bother with this one!

Easy to charge. I can input microphone, guitar and backing tracks. Good sound to easily fill a small gig (village hall, care home venue, fete etc)Recommended

Easy to carry easy to use battery lasts for ages not sure why it was covered in dust the glue on the badge on the front is strange not sticking just let's the badge slide around reverb is really good I use it with my electric guitar not acoustic work well

This is the second amp I'm putting my trust in the last one lasted 4 month
