All-tube design delivers big sound

Utilizing a cathode-biased KT66 power section and GZ34 rectifier, the Astoria Custom gives you a wide range of tones with a definite Marshall vibe. The Astoria Custom was designed for players who want vintage tone with modern features such as an effects loop and footswitchable gain. The gain knob also houses a body switch that adds a different EQ curve to your tone. Handwired in Bletchley, England, Astoria amps use turrets mounted to printed circuit boards that let complex switching and handwiring exist in the same amplifier. Sweetwater knows that good tone is important to you, and we're confident that the Marshall Astoria Custom can do the job.

Boutique vibe and classic Marshall tone

The all-tube Marshall Astoria Custom tube amp combo delivers fat British tones in a stylish and great-looking package. The top-mounted control panel, leather carrying strap, and old-school Marshall logo badge are a nod to Marshall amps from the '60s. The eye-catching two-tone vinyl covering and boutique cabinet design are sure to set this amp apart from the crowd.

Dial in practice levels with onboard power reduction

Thanks to the Astoria Custom's onboard power reduction, you can retain all that tonal richness even at low volumes. Imagine being able to plug your guitar into the same thick, sustaining tonality in the practice room or studio that you get when it's wide open on the big stage. With the Marshall Astoria Custom, all it takes is a simple pull of a knob.

Marshall Astoria Custom 1x12

First off this amp is no where worth what it costs!! Build is good, but the why it sounds in its stock form is almost terrible. The only reason I kept it was because I could tell with a little work it could be great. The first thing to go was the awful bullhorn sounding speaker!! This is without a doubt the worst speaker I have ever heard in a guitar amp!! It fights you with authority if you try to dial any tone or sweetness to it. Next to go was obviously Marshall's poor choice of tubes, don't know who makes them but their the shrillist sounding little things. And last was a mod done by my tech to tame/sweeten the mids. Now I have a great sounding amp, but not after adding another $ on top of the already outrageous price!!! I feel completely misled by Marshall and especially all those YouTube videos out there, they are absolutely inaccurate!! It will definitely be the last new Marshall I'll ever buy!!
