There’s good reason why the Marshall AS50 is so popular with acoustic guitarists, they offer really versatile connectivity options for instruments or microphones, and at 50 watts with 2 8 inch speakers and a separate tweeter, the AS-50D sounds rich and clear and is easily loud enough for small gigs and rehearsals, but can also be turned down low enough for home practice.
They look really stylish with their brown and gold colour scheme, and best of all, they’re actually really affordable. The AS50 features two channels, so you can either connect 2 acoustic instruments, great for duos, or a guitar and a microphone if you’re a soloist. The guitar channel input is compatible with both passive and active pickups, and channel 2 gives you the option of either a standard 1/4 jack instrument input or a balanced XLR microphone input which also supplies 48v Phantom power for condenser mics. Plus there’s a dual RCA phono input to connect a phone, tablet or MP3 player for playing music through the amp.
Each channel has separate volume and EQ controls to balance your mix, adjustable chorus and reverb effects allowing you to thicken up and add depth to your tone, and an adjustable notch filter and phase reverse switch are really useful to tune out any frequencies that may start to cause feedback as you turn the amp up to gig levels.
On the back of the amp you’ll find a DI out and a line output, so you can connect into a PA system but still use the amp on stage as a monitor, there’s an effects loop for if you’re using any external effects pedals, and a foot switch input allows you to remotely toggle the reverb on and off, great for when you’re talking through a microphone in between songs. The Marshall AS50D, it’s been one of our favourite acoustic guitar amps for over 10 years now, and it’s still going strong.
