For me this is the best review of this product I've seen. Clear explanations, nice close ups, so I can see exactly what the controls are and what they do. Audio demo was really nice too. I'm pretty certain that this is the one I want, now. Thanks.

I have two BP40’s now… I tried it with short scale bass at home and it did ok, but did not crank it loud. I’d rather play through my Fender Rumble. I use them for keyboard or acoustic guitar or as monitors for the band. I love having 48volt phantom power onboard too.

Thanks for the excellent review Mundo. The orientation versatility has me captivated. Rechargeable portability lets me be free. Still confused by the Bass Boost switch advertised amongst the specifications by coolmusic. Have you tried pulling on any of the knobs? What is the Bass response really like?? Was that a attenuation switch I saw next too the Line out volume knob? Please excuse all the questions. I'm making a investment in my future and taking everything into consideration. It sure sounds alot like the clean sound of a Street EX but without that digital processing quality audio. Seems like a excellent Keyboard and Vocal amp perfect for busking or Mob Flash events.

Question for you. As for the mic inputs. Is one a QTR input and the other an XLR or are they both the 1/4? I'm going to be using 2 mics on this baby and have one that's a 1/4 jack. Need to know what to buy as a second mic or an adapter. Thanks in advance and thanks for the review and sound sample. I was going to buy the orange BP80, but not keen on that orange. This blue is much more appealing. Glad to hear it has plenty of power and sound for my needs.

[@mundojuillerat]

On Input 1 there is one XLR that can accept a 1/4" and also a separate 1/4" input jack. On Input 2 it has two separate 1/4" input jacks. Hope that helps ?

[@anthonynieto8296]

Thanks

[@DaveZiffer]

An amazingly important question that neither Coolmusic nor any of the reviewers I've seen is: What do I do when the battery dies (i.e. can no longer be charged)? Older portable amps used standard sealed-lead-acid batteries (SLAs) that have been sold for decades and will probably be sold for decades to come. SLAs die after three years whether you use them or not. My old Crate Taxi amp, for example, makes replacement easy: unscrew a few screws, disconnect the standard battery connectors, take the old battery out, put the new one in, reconnect the connectors, screw the cabinet back together. My questions for Coolmusic, which are not answered in their manuals, are: 1) What specific batteries you use in your amps (exact models)? 2) Is the amp built in such a way that I can easily replace them? 3) Where I can buy replacement batteries? 4) What are the prospects for these batteries still being sold many years or even decades from now?

[@mundojuillerat]

David great question and honestly I have no idea ha! Shame on me for assuming it would last. But so far after a few years it has for me and it still hold's it's charge well.

I have this amp. I'm generally happy with it but the internal battery went bad after 2 years of use. Now I use an inverter with a small lithium battery to power it. It would be nice if it had an easy to replace battery. I'm seeing other owners with this same complaint.

Would like to hear you play more nylon string guitar individual notes, chords in other words maybe like in a Brazilian style, that’s what we do, we do a lot of Brazilian stuff and Mexican and other Latin American FOLK MUSIC, so we don’t really use steel string guitars I haven’t found any demos of this amp with a classical guitar technic and it would like to hear a little more so if you do, it would love to hear you Mundo and thank you for being so thorough with your great video.

Paul I apologize- I answered this already but it didn’t post (a bunch of my replies didn’t post-must be me!) Anyway yes I have played the loud box. Don’t know if it was the mini but it was small. I think the Fishman sounds good although it does add a certain “Coloring’ to your sound. Not necessarily a bad thing but I didn’t find that on the Coolmusic amp.

[@mundojuillerat]

Loudbox's are great too! I think the sound has some coloring to it but that's not a bad thing if you like it. I think this amp offers you more bang for you buck tho.

[@timzitzelsberger3200]

It's a signal out not a speaker out there is a great difference between the two

[@barfboy2000]

you would need an amplifier or the external speaker would need to be self powered. some self powered speakers want balanced input, which is a good idea if your running a long distance. A long unbalanced low voltage run is asking for noise.

[@benjamincardenas4219]

I have a Roland street EX. I love what it is, it’s a great portable PA and an OK amp. The problem is the premium price. The Roland does have its flaws. 1. No Bluetooth 2. Price 3. Mediocre amp sims, uses old COSM not Katana or boss GT tones. 4. No D.I for recording. I always said to myself if someone made a less pricy portable PA that meets the specs as the Roland streets, ha someone just did. Roland just released a gen 2 of Roland street cubes, they don’t include BT, so all the deep editing can’t be accessed, and nothing else was upgraded not even the guitar tones, they have a katana and a boss gt tones would have been an upgrade, and yet they still raised the price of a 12yr old reboot, not impressed Roland’s value additions. This unit seems like it will be my second portable PA, now I will have a stereo set up with $ to spare. I’ve been waiting for a second CUBe, but this is perfect. Thanks

Yeah I'm in the same boat with two Roland street EX amps for a battery powered gig far away from any power lines. Need another two battery powered amps for a quad surround immersive effect, but the Street EX are to expensive to buy again, so I'm looking at these Coolmusic BP series of amps with there very clean sound and adapt-abilities. The Price is right.

[@martinespinomusic]

Yeah, I had the Roland Street Cube EX and I was totally unsatisfied with how a classical guitar sounds. I think steel always cuts through but nylon most of these amps out there and pick ups. Make it sound like it’s a nylon string guitar being amplified through shitty pick up I like the sound like a louder, nylon string guitar not an amplified nylon string guitar. That’s a really hard thing to get. That’s why I like to hear this amp played by a classical guitar player or unless Mundo can do it I’m sure he can. Yeah I was so unsatisfied even when I use the microphone and played my foot through it all these Native American flutes that I have it still didn’t sound that because the reverb was really shitty on the Roland. It sounded like a really bad spring I didn’t like it at all and so I wouldn’t go with the Roland at all if you’d like to retain “an acoustic sound“. And I am a great fan of Roland so don’t get me wrong. I have a lot of their equipment it’s just that this amp does not meet at the cool music amp sounds like it might be the thing if anything I like it because of all the features it has, and you can’t get that for anything that’s at that price but yeah, I forget the Roland. I bought the acoustic sonic 90 which is also discontinued and it does not sound like it had an 80 W of power it was not loud enough for my very quiet Jazz Quartet, so it just doesn’t have the balls. The instrument sounds good on the sender. The fender is made for acoustic instruments and a classical sounds wonderful there and the flute sounds come out really good to reason I’m going to sell my fender is because it does not sound like it has 90 W of power it doesn’t have a lot of power and so I’m thinking of the BP 80 or whichever one one of them has 100 W and I’d like to get that one instead and then with all the features well the fender doesn’t even have those features at all
