Features 5

  • 40W ACOUSTIC TONE BALANCED SOUND FOR VOCALS & GUITAR: It delivers rich, natural acoustic tone through a custom 2-way speaker: a 6.5-inch woofer for warm, punchy lows and a 2.75-inch tweeter for crisp, detailed highs. Whether you're fingerpicking or strumming, guitar's true voice comes through and vocals stay clear and present in the mix. 40W is ideal for busking, coffee shop gigs, travel and home studios. At just 5.7kg, it's your portable performance partner.
  • DUAL CHANNEL WITH STUDIO EFFECTS SEPARATE CONTROL FOR GUITAR & MIC: Independent channels let you dial in the perfect sound for both guitar and voice. Each channel has its own volume and EQ. Built-in CHORUS, DELAY and REVERB effects. Add shimmer to your acoustic, space to your vocals, or depth to your solo performances all without extra pedals. (Mic input supports XLR and 1/4" dynamic mics no phantom power.)
  • 20 DRUM PATTERNS & TAP TEMPO RHYTHM SECTION ON DEMAND: Never practice alone again. 20 built-in drum patterns (rock, pop, blues, jazz, and more) give you a solid rhythmic foundation for practice, songwriting, or solo gigs. Tap Tempo lets you match the speed instantly no menu diving. A creative tool, not a replacement for a full drum machine.
  • STREAM, RECORD & PERFORM ONE AMP, EVERY SCENARIO: USB-C OTG and dual 3.5mm jacks for direct recording and live streaming by phone. XLR DI Out for PA systems and small gigs. AMP IN/OUT to link two amps for larger sound coverage. Bluetooth and AUX IN for backing tracks. Headphone out for silent practice with speaker mute. Speaker Stand Mount 270 standard pole mount for outdoor performances.

Description

The BSK-40 is ideal for home practice, live streaming, street performances, rehearsals, and small indoor performances. When using it outdoors, place the amplifier on a speaker stand and point it toward the audience for better sound projection. Check guitar & MASTER volumes, center EQ, reduce effects. Test cable and guitar with another amp. For active pickups, replace battery and raise onboard volume. Pickup output levels vary widely. Check guitar is in GUITAR input, not AUX/OTG/output. Use known-good cable and test another guitar. Increase guitar channel & MASTER volumes. For active acoustic-electric, replace pickup battery. Set BASS/MID/TREBLE near center, reduce CHORUS/DELAY/REVERB. Adjust EQ gradually while playing. Too much bass/effects sounds unnatural. Tone also depends on pickup, preamp, strings, and position. It is designed primarily as a portable acoustic guitar, vocal, busking, and small-performance amplifier. It may not provide enough projection to compete with drums, loud electric guitar amplifiers, or a large outdoor crowd. For those situations, use the DI output to connect the BSK-40 to a larger PA system. No 48V phantom power on BSK-40. Use dynamic microphones. Condenser mics need own power or external phantom supply. The BSK-40 does not provide a supported footswitch connection. The built-in effects, drum patterns, recording functions, and channel settings are controlled directly from the amplifier’s control panel. Connect guitar & mic before power-on. Set channel volumes low, EQ center, effects off. Power on, raise MASTER gradually, adjust each channel. Add reverb/chorus/delay only after clean signal is confirmed. Not only for electric guitarists, JOYO has also designed a unique pedal for bassists. BSK-40 is able to fit in the different connection types including wireless connection, DI Out, 2 amps can be connected in series, headphones and micphone. What type of product is BSK-40? Multi-functional acoustic guitar amplifier with singing & live streaming functions. With the guitarist’ s needs in mind, we’ ve redesigned it from appearance, functions to algorithm. It can be used for about 5 hrs outdoors once fully charged.

This Joyo Amp delivers on Everything you need for just practice or busking on the street!
Color: Black
I was wanting something to practice and utilized in live streaming. It seems to work great. I have only used to practice and record some music, but love the battery life and the quality of the sound is great! I love my JOYO and believe it is the best bang for the buck on Amazon!

Buyer Beware. Low volume.
Color: Black
Absolute junk. Super low volume, lower than my Spark Go. I can plug my instrument and mic into ANY of my other amps like the Spark Edge or Spark Live and they work just fine. Plug it into the Joyo BSK 40 and both mic and instrument are wildly low. I'm looking for something lighter than the edge and live. The bsk 40 is NOT it. ... show more

It does it all!! I love it. I’m considering getting a second one , they can be contacted together. If you are looking for a battery powdered, on the go amp, this one is great.

Great features but sound output is like a 5W practice amp.
Color: Black
Great features, compact size, smooth sounds! My only criticism is a lack of volume. My 10W Squire practice amp is louder.

Great portable amp
Color: Black
It works as described. Sound quality is good. The initial full charge exceeded my expectations. The 20 pre-set drum feature is of little use but it was not a factor influencing my decision. I like the portability and power.

Decent amp.
Color: Orange
I have had this amp for several months now and wanted to run it through it's paces before reviewing it. There were a couple of deciding factors to purchasing this brand over others. Number one is you can actually use it on a speaker stand. Doesn't sound like much of a feature but it certainly is if you want to use it outdoors and be able to project the sound well. I use it for a ukulele and microphone. Do I get a great natural ukulele sound from it? Not at all and that's why I didn't rate it higher. All of the functions work as they should. The drum machine is hokey and mostly worthless in my opinion. There doesn't seem to be a footswitch option so I'm dinging it for that as well. Another option that should be included is phantom power for condenser mics, but it doesn't have it and many others lack it as well. All in all I'm fairly happy with it, but certainly could be happier. ... show more

Quality Sound and Built like a Tank
Color: Black
I was looking for amp that I could use at home for practice and for small gigs. Also I heard that acoustic amps can be used as an FRFR speaker. I plugged in my Boss Gt1000 and it sounded awesome. The EQ knobs help tweak your sound nicely. A great buy for sure. BTW, it is light and comes with a nice case. ... show more
