Description

Edit description

The Marshall Model 2021 Reverb-Fuzz Unit is a versatile addition to any musician's studio setup, combining classic reverb and fuzz effects in one powerful unit. This effects processor is designed with both vintage enthusiasts and modern sound engineers in mind, allowing users to seamlessly blend the rich, ambient tones of reverb with the gritty, distorted textures of fuzz. Whether you're looking to enhance your recordings with subtle warmth or create bold, experimental soundscapes, this unit offers the flexibility to do both.

One of the standout aspects of the Model 2021 is its integrated dual-circuit design, which ensures that both effects maintain their integrity without compromising on audio quality. The unit features separate controls for reverb and fuzz, allowing for precise adjustments to tailor your sound exactly as you envision it. Additionally, its true bypass switching ensures that your signal remains pristine when the effects are not engaged, preserving the original tone of your instrument.

Perfect for studio recording applications, the Marshall Model 2021 is also built to withstand the rigors of live performance. Its robust construction and intuitive interface make it a reliable choice for musicians at any level, from bedroom producers to seasoned professionals.

"It (the ES-335)’s had many different amp partners. A Vox AC 30 ‘top boost’ in the studio for several years, again through the Normal channel, a Marshall 100 watt and 50-watt, two High Watt stacks (see the 1970 Isle of White DVD when it eventually comes out). The DVD sounds great by the way. A Marshall fuzz unit that I used on recordings through the 70’s and 80’s, and at other times with just a small standard compressor (that’s all there is on my 335 for the Blue Guitar solo sound at the start of the record, that’s how good an recording engineer Eric Stewart was), an Eventide Harmoniser, and lately a Mesa Boogie, a Matchless 30 and a Fender Custom 30 watt, as well as my old Marshall 50."
