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

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.

This is the best portable amp I've used. I was dubious about its' ability to handle the electric bass but it's not a problem. Excellent sound and build quality. I haven't rated the battery life because I've only used it for 2 hours at a time - but I don't doubt it will live up to the description of up tp 4 - 6 hours. Well worth the money.

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.

This items is faulty. Adapter is damaged and charges intermittently. input 1 is good ,but input 2&3 are very low. After 8 hrs of charging this product battery is non existent. You can only use this with a power supply which defeats the purpose.Either this is not worth it or I have a damaged product. Amazon!!! come and collect this junk.

The amp quality is quite good on average. I am satisfied with the battery life. It is acceptable to carry it around.

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

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.

This little battery rechargeable amp is well made and sturdy I use it to play my acoustic bass guitar through and it gives a good warm distortion free sound and a 40 wats of power more than enough for small venues also with a 6 hour +battery life it is as good as any comparable amp costing over 500 £ very good value for money

+ Laddningsbar, vikten, storleken, att den har tre mick/instumentkanaler, bluetooth, hörlurs- och line out samt line in. Den är egentligen helt perfekt om det inte vore för minusposterna: -Ljudkvalitén är inte mycket att hurra för, inte ens när man spelar upp via Bluetooth eller line in. Den är uppgiven till 40 W men kan inte ge mycket mer än 5-10 på sin höjd. Om man kostat på hårdvaran 500 Kr till hade den blivit en hit, även vid ett högre pris.

One amp for all my instruments. This thing not only looks great, but it is versatile and delivers. The diversity of input ports that this amp has is all I need now to jam at home. Great product!

I bought this because it had a DI output that lets you add a speaker, others I had bought, the output didn't work or wouldn't work with bluetooth on. I tested and it works great even with a wireless guitar transmitter and reciever set up so that I don't have to run a 1/4 inch cable between the speakers. It worked well up to about 100 ft. Only thing I did notice was with bluetooth playing the wireless mic I added lost most of it's volume. If you are DJing you might need to use a wired mic or look at other posibilities. I have no clue how it it will work in a year but sound quality is good and volume is very good for it's price and size.

Molto soddisfatto dell'acquisto, ha tutti i requisiti che cercavo e anche qualcosa di più ad un buon prezzo. La qualità dell'audio per amplificare chitarra acustica e voce è più che soddisfacente dovendo lavorare l'amplificatore su frequenze "normali". Ho provato ad amplificare anche la mia batteria elettronica e sulla bassissime frequenze della grancassa e le altissime dei piatti fa onestamente una gran fatica e non rende bene i suoni, ma nonostante tutto regolando bass e treble al massimo si può ottenere un suono dignitoso. Graditissima la funzione bluetooth, così come l'entrata aux in e le uscite jack 6.3 stereo e jack 6.3 per cuffie che muta in automatico l'amplificatore, serve però un riduttore per passare dal jack 6.3 al jack 3.5 standard per le cuffie. Ho provato la funzione riproduzione musicale da USB e funziona, non ho provato la funzione di registrazione ma non ne ho onestamente bisogno. Qualità materiali sembrano molto buone, piccolo ingombro e peso, graditissima anche la batteria per funzionare senza alimentazione. Ulteriori note le manopole per il riverbero ci sono e aggiungono un effetto riverbero non particolarmente evidente. Bella anche la predisposizione per uso in verticale appoggiato a terra o installato su palo, davvero un amplificatore versatile completo di tutto
