It offers versatile connectivity options including Aux In, Headphones Out, and Line Out, plus a three-band master EQ for precise sound shaping. ## Description The compact and lightweight VX series is joined by a new 50W model, specialized for keyboard and featuring Nutube, the new vacuum tube. With a coaxial speaker that outputs clear sound even to the high-frequency range, and a bass reflex structure that reproduces rich low-frequency sound with ample power, this amp delivers high-quality sound from a compact and lightweight unit. The three-channel design provides an independent volume control for each channel, and CH3 also supports mic input. The Vox VX50 KB keyboard amplifier is built with a focus on durability and portability. Its lightweight, sealed ABS body ensures robustness while keeping the amp easy to transport. This construction ensures reliable performance and longevity, making it suitable for both studio and stage use. The back of the Vox VX50 KB keyboard amplifier is designed for user-friendly functionality and optimal performance. It features a conveniently placed DC power input for easy connection to the power adapter, ensuring consistent operation. Additionally, there’s a footswitch input for seamless integration with a compatible footswitch, enabling hands-free control of the amp’s versatile features. The three-band master EQ with BASS, MIDDLE, and TREBLE controls is common to the three channels. It provides basic and flexible control that you need to shape your sound. In spite of its high 50W of output power, the lightweight 4.1 kg (9lbs) body and compact design mean that transportation is easy. The one-piece ABS chassis ensures high durability and great sound quality while keeping the weight light. By using Nutube, the new vacuum tube, this amp achieves an output power of 50W while being compact, lightweight, and power-efficient. In addition to enjoying the rich overtones and sonic power of vacuum tubes, you’ll also appreciate the clear tone with compression that particularly enhances piano and electric piano sounds. The coaxial two-way speaker features a powerful eight-inch speaker plus tweeter. From a bountiful low range to clear highs, the output is transparent-sounding while ensuring a sense of volume. Another major advantage is the excellent sense of positioning that you receive from the VX50’s coaxial speaker. Even the sparkling highs of a piano or synthesizer will be expressed in every detail. A proprietary, optimized bass reflex structure is used, with every detail adjusted specifically for the response of keyboard instruments. The chassis uses ABS polymer for its light weight, durability, and excellent acoustic properties. This allows for a 3D design that would be impossible with wooden material and achieves the ideal cabinet resonance. In addition, wood is used for the baffle, achieving the optimal resonance for a keyboard amp. While the chassis is polymer, a distinctive sense of high quality is emanated by the stony-finish exterior and a white/black color scheme based on a keyboard motif. This unit’s three-channel design meets the needs of any scene: three keyboards, two keyboards and a mic, or a stereo keyboard output plus a mic. It can also act as a simple PA system. In addition to a master volume, independent volume controls are also provided for each channel 1–3. Furthermore, each channel also has a CLIP indicator to prevent distortion caused by excessive volume. CH3 is also equipped with a PHASE switch. When a mic is connected to CH3, this switch can be used to correct phase interference with instruments that are connected to CH1 and CH2 or to reduce low-frequency acoustic feedback. A full complement of input/output jacks are also provided, including an AUX IN jack for connecting your audio player or rhythm machine to enjoy jam sessions, a LINE OUT jack that can be used for connection to a PA system, and a headphone jack that’s ideal for practicing at home. ## Features - 50 watts of output power; NuTube-equipped preamp - 8" coaxial speaker; Bass reflex structure enhances low-end - Three-channel design, with independent volume controls - Aux In, Headphones Out & Line Out - Three-band master EQ for ultimate control ## Technical Specifications | Specification | Value | |---------------|-------| | Amplifier Type | Tube | | Asin | B075QKK2N6 | | Best Sellers Rank | #62,644 in Musical Instruments (See Top 100 in Musical Instruments) #9 in Keyboard Amplifiers | | Brand | VOX | | Built In Media | Instruction Manual | | Color | White | | Compatible Devices | Keyboard | | Connector Type | 3.5mm Jack | | Customer Reviews | 4.2 4.2 out of 5 stars (85) 4.2 out of 5 stars | | Enclosure Material | Stainless Steel | | Global Trade Identification Number | 04959112170643 | | Item Dimensions D X W X H | 8.19"D x 12.32"W x 13.94"H | | Item Weight | 4.77 kg | | Manufacturer | Vox | | Mfr Part Number | VX50KB | | Model Name | VX50KB | | Model Number | VX50KB | | Number Of Bands | 3 | | Output Channel Quantity | 1 | | Output Wattage | 50 watts | | Power Source | Coaxial | | Speaker Size | 8 inches | | Warranty Description | 1 Year | ## Product Details - **Brand:** VOX - **Compatible Devices:** Keyboard - **Material:** Acrylonitrile Butadiene Styrene (ABS) - **Output Wattage:** 50 Watts - **Product Dimensions:** 8.19"D x 12.32"W x 13.94"H ## Images ![Vox VX50KB 50-Watt Keyboard Amp - Image 1](https://m.media-amazon.com/images/I/81leBcfr1ZL.jpg) ![Vox VX50KB 50-Watt Keyboard Amp - Image 2](https://m.media-amazon.com/images/I/81etGrPvK+L.jpg) ![Vox VX50KB 50-Watt Keyboard Amp - Image 3](https://m.media-amazon.com/images/I/81t0aa6NmLL.jpg) ![Vox VX50KB 50-Watt Keyboard Amp - Image 4](https://m.media-amazon.com/images/I/91UFfempGdL.jpg) ![Vox VX50KB 50-Watt Keyboard Amp - Image 5](https://m.media-amazon.com/images/I/71+cr9qdfKL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Ist great *by on Reviewed in the United States August 2, 2026* It's amaizing !!! Just unreal sound my be the best keyboard amp on the market. Super light and plenty of volume for small to medium gigs. I just love the thing. Worth every penny! ### ⭐⭐⭐⭐⭐ Has A bigger sound presence then I expected *by on Reviewed in the United States November 26, 2023* I used the Vox keyboard amp I just purchased through Amazon just the morning at church. Needless to say, I was very very surprised at how well it performed. We presently don’t have a large forum and meet in a meeting hall and this is just perfect for that kind of set up. It only weighs 8 pounds and has more sound than I originally thought I needed. I’m extremely impressed that it works so well for being so I small and light weight! ### ⭐⭐⭐⭐ Does what it's built for *by on Reviewed in the United States April 17, 2024* I was surprised that the materials were kinda cheap and looks somewhat toy-like. However, the sound quality is good for a practice amp and it's lightweight and vert portable. ## Frequently Bought Together - Vox VX50KB 50-Watt Keyboard Amp - JOLGOO 1/4 Inch Cable Guitar Cable 10 Ft Straight to Right Angle 1/4 Inch 6.35mm Plug Bass Keyboard Instrument Cable Blue and Black Tweed Cloth Jacket, Electric Mandolin, pro Audio --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.br/products/54545046-vox-vx50kb-50-watt-keyboard-amp](https://www.desertcart.com.br/products/54545046-vox-vx50kb-50-watt-keyboard-amp) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-08-15*
