## Description

desertcart.com: JOYO 5W Mini Guitar Amp Portable Electric Guitar Practice Amplifier with Bluetooth 5.0, Clean/Overdrive Channels, Rechargeable Battery, AUX & Headphone Out (JA-02 II Blue)

Review: Great highly portable amp. - Perfect for the money you can't get better Even as a Bluetooth speaker it's cool with tone and drive control. Good sound and long charge life. I would totally recommend it
Review: Holy Cow!! - I got this because it's cute, pink, small, inexpensive, and I needed something to kick around the house [finally, I can leave my main rig set up in the studio]. I would have been happy if it was "just ok", but it's surprisingly fantastic! I'm honestly impressed with how good it sounds for the tiny size. It doesn't have the massive low end of larger speakers, but it has enough bass that it still sounds good. The built in overdrive sounds fine but your fav OD pedal might serve you better. Luckily this thing loves pedals! You'll want an EQ pedal if you prefer a mid-scooped tone, otherwise the tone knob works just fine. The battery seems good as far as I can tell. It has a nice little charging light that turns off when the battery is full. 10/10, would recommend to anyone who needs an affordable amp that likes pedals and doesn't need to compete with the volume of an acoustic drum kit.

## Features

- PORTABLE PRACTICE ANYWHERE: Build in Dual 5W Speakers: weighing just 330g (11.6oz), JA-02 II is compact yet surprisingly loud. Perfect for practice anywhere — bedroom, dorm, or park.

### ⭐⭐⭐⭐⭐ Holy Cow!!
*by M***Y on October 14, 2025*

### ⭐⭐⭐⭐ Solid for the size and price
*by N***S on July 24, 2025*

I bought this with pretty low expectations figuring that, worst case scenario, it would sound awful but in an interesting way but it actually sounds pretty decent overall for an amp of this size and price. It's portable enough that I can easily take it wherever I need it but loud enough to hold a presence in my living room with company or the TV going. The inclusion of aux and headphone jacks are great though I haven't used either yet. The distortion is also surprisingly heavy for such a lil guy. The only real complaint I have is that it could use an LED by the charge port to indicate charging/done charging/battery life but that's pretty minor. I've only had it for a couple weeks but as long as it doesn't fall apart or stop working in several months then I think it's a winner for a cheap, portable practice amp.
