    • Roland killer (unless you need onboard fx/ electric guitar amp models)!
Color: Black
I don't usually leave reviews, but considering how pleased I've been with this product and how often I use it, I'd like to give er a boost. I've been a busker for over ten years now, and until now I - like probably 90% of other buskers - used Roland/Boss products like the Cube Street and its big brother, the Cube Street EX. This amp handily beats the Cube Street in nearly all categories for $150 less and holds its own against the EX, for nearly $400 less. PROS: - Sound quality. Sounds grand for what it is. Plug in a mic and an acoustic guitar, and you'll get a sound that's surprisingly faithful to the source. Much better than the smaller (Boss) Cube. Playing back music via Bluetooth will give you a good idea of what you're working with - it's quite mid-rangey, like most smaller amps, and not particularly detailed, but with a fairly solid, only slightly muddled low-mid end, and a nice bit of "oomph". The top end isn't anything special. If an airy, modern-sounding top end on your vocals is a must, the Cube Street EX does a better job at that & might be worth the extra cash. - Loudness. I was wavering between this amp and the bigger version, the BP60D, but I'm glad I picked this one as it's a lot more portable and plenty loud. I've yet to have any need to go beyond about 12 o' clock on the master volume knob, and around 10 o' clock is where I'm usually at for outdoor settings like farmers markets where you're not trying to be overpowering. - The battery. Unlike the Roland/Boss amps, which use AA batteries, this one is actually rechargeable - and it lasts substantially longer. I used rechargeable AAs for my Cubes, but that's an extra cost and it was a hassle having to pull out the batteries, charge them, and put them back in every time. - Bluetooth for playing tunes off your phone or karaoke/backing tracks. The Cubes have an aux in, but that means carrying an aux cable (and a lightning adapter if you're using an iPhone). - The USB socket is powered, meaning you can use it to charge your phone, or even better, power your guitar pedals with up to 800mA of power (if you buy a USB to 9V center negative cable). - Phantom power. Admittedly not something that's going to see a lot of use in most live settings, but fancy to have. - Output. 80W in this tiny box, compared with 50W for the EX and 10W for the Boss Cube. - Portability. It's much smaller than the EX and packs about as much punch. - Inputs. Two microphone inputs and two instrument inputs, as well as a basic line-in and the bluetooth connection makes for six channels, comparable with the Cube Street EX and far outperforming the smaller Boss option, which has only two inputs. CONS: - NO ELECTRIC GUITAR AMP MODELING! And the gain is clean, you won't get any overdriven/distorted sounds out of this. You could get around this (and get a sound much better than Roland's COSM) by using a modeling pedal like the Strymon Iridium or one of the UAFX amp pedals. But if you want electric guitar amp modeling in the box, Roland is still the way to go. - No onboard effects aside from EQ/Reverb, and the reverb sounds like arse. However, you can always get your effects thru pedals powered by the USB port or a rechargeable pedal power supply. - Default EQ balance - on acoustic guitar I've found it's actually a touch too bassy - I tend to dial it back to about 10 o' clock to keep it under control. But usually smaller amps have the opposite problem, eh? - (Possibly) Build quality. The sides aren't wood or plastic, but some sort of composite board material. It's not terribly substantial. If you remove a screw, some of the material will come out with it. And you're going to want to be careful with rain, if playing outdoors. I was careless and let mine get pretty damp a few times, and after one particularly wet session it wouldn't power on anymore. That was obv on me, and I was ready to purchase a new unit, but I figured I'd take it apart and see if I could repair it. It disassembles easily and the electronics are straightforward enough. The problem turned out to be the power switch, which went tits up for whatever reason. I was able to replace it with a cheap generic rocker switch for about $5. But obviously not everyone's gonna be able to troubleshoot that sorta thing. I couldn't say whether this component is a weak part, whether there's other weak components or whether I just got unlucky, but you might want to pay the $35 extra for a 3-year warranty if you plan to use this amp a lot. All in all, I'm betting this company will be a nice kick up the arse to Roland to start upgrading their line. It was only a matter of time before there was some more competition in this field, considering how much better both battery technology and the sound quality of portable speakers have been getting. If you were thinking about getting a Boss Cube Street and you don't need FX or amp modeling, get this one instead. And if you were thinking about getting a Roland Cube Street EX, I'd seriously consider this lil amp as a solid alternative. If you need an affordable live monitor, this'll do great. If you're very quality-focused and have $700 to spend, I'd consider the Bose S1 Pro+ as one of the only clear upgrades out there. ... show more

    • A great portable amp
Color: Black
Review of CoolMusic BP40D (Background: Electrical Engineer, Age 77, Ham Radio Op - so I know equipment) I have 2 other amps, but I wanted a fully portable amp that had two input channels - one for mic and one for guitar. I wanted an XLR input for the mic. I wanted a real amp, not a toy with a 4" speaker. I was less interested in fancy DSP processing (see Spark). The BP40D fills the bill, and at a great price. Although a bit heavy (15 lbs) and big, I was willing to sacrifice that to get the sound that I wanted. Pros: - Loud, great sound. The two 6" speakers and tweeters do the job. - Terrific battery life. I ran it for 7 hours playing via the Bluetooth input, and the battery was only 1/4 used. It charges fairly quickly. (Your results may differ) - Nice control panel layout, very logical. Good quality controls and switches. Cons: - does not have the 9v output for effects pedals that other CoolMusic amps have. This would be nice but not a serious issue for me. - Size and weight - but if you want a sweet sounding amp, you have to pay this price. Other nice features: 48v phantom power so you can use a condenser mic - a nice option. Allows external Bluetooth connection so you can use it to play music between sets. Reverb, chorus, and delay work OK - nice to have but you will probably want to use external pedals for better control if needed. Carrying handle. Hole in the side so you can mount it on a speaker stand. Line-In / Record-out could be handy. Headphone output with separate volume control. So it's a great sounding, fully-featured amp at a great price. A winner for me. (No connection to CoolMusic) ... show more

    • BOSE-LIKE QUALITY WITHOUT BREAKING THE BANK!
Color: Black
I don't know of a single battery-powered unit that can sound this good and loud, with fine rich tones and more than the COOLMUSIC BP40D Battery Powered Amplifier and Portable Bluetooth Speaker. I purchased the BP40D back in April 2024, and after the initial charge, in late April, I only had to attempt a new charge in late July 2024. Despite playing it outdoors with my acoustic-electric Martin guitar and a microphone plugged in, the charge held, from playing at an outdoor Boy Scout Jamboree to practice at home. I was first inspired to purchase it after a fellow musician, who did a lot of small gigs at campgrounds, senior homes, and more, told me he used the BP40D and its many qualities. It is absolutely, the best fit for a single musician or two to use, with both their instruments and microphones plugged in, without sacrificing rich Bose-like quality....yet at the most reasonable price ever. The size and portability are what sold me on it. I even stopped using my Boss Katana 100 W Amp, since this Coolmusic BP40D sounded better, had better reverb and gain, was lighter to transport, and did not require a separate sound system for singing or speaking! The output was also louder and clearer than my Boss Amp, as my guitar amplifier. Serious full-time musicians or part-time music enthusiasts like me can benefit from keeping one or more of these in their arsenal. I highly recommend for first-class Bose-like quality, without breaking the bank, in these tough economic times. You won't regret it. In addition, the Coolmusic Corporate office is extremely kind, helpful, and responsive to any questions or concerns you may have. I am 100% satisfied with both the product and the manufacturer. It is the BP40D Amplifier System and Bluetooth Speaker, for your electronic music needs. ... show more
