Critic Reviews

Marshall RG-1 Regenerator review | MusicRadar

musicradar.com

The Marshall RG-1 Regenerator offers a surprisingly affordable route to classic Uni-Vibe sounds, with a step phaser that's a standout feature for its price. Despite its vintage appeal and solid build, including a user-friendly battery access panel, the Regenerator's other modulation effects like chorus, flanger, and phaser fall short when compared to dedicated stompboxes. While the vintage vibe and step phaser modes shine, the overall package doesn't quite reach the heights of more specialized pedals, making it a mixed bag for musicians seeking a versatile modulation tool.

Marshall's RG-1 Regenerator Modulation Pedal is a versatile addition to any pedal board, offering stellar chorus and flanger effects that don't compromise your amp's tone. Its standout Step Phaser inspires creative play and shines in a variety of settings, from clean to high-gain. However, the pedal's usability is hindered by its polished knobs, which make settings hard to read, and the lack of multiple memory settings limits its potential. Despite these drawbacks, the RG-1's sound quality and rugged build make it a worthwhile consideration for modulation enthusiasts.

Great Modulation Multi-FX

This is a hidden gem. It has two different chorus options, a flanger, a phaser, a step-phaser (nice gimmick but rather unusable in most contexts) and a uni-vibe mode. All of these do sound very good and can be dialed in to many different sounds. For its price you get a ton of value. This item saves a lot of space and money. If you can get one, buy it, you won't regret it.

Super Versatile for Modulation-Lite Players

6 different flavours of modulation means you'll never tire of this pedal. It won't completely sound the same as certain classics that specialize in one effect, but unless you want more than one modulation effect you won't have to swap pedals on and off your board when you want something different. Expression pedal option is a tasty bonus that I've never used.

Some cool sounds but nothing more.

I bought this second hand and it is little more than unremarkable. Some sounds do however occasionally excite.

Positives: The sounds are all passable at least. The step phaser provides an interesting and unique effect that is enjoyable to use, if a little volatile. In addition the pedal also has some interesting extreme settings including Electric Mistress like fixed flanger sounds.

Negatives: The effects are all highly sterile and do not interact well with other pedals. The pedal itself seems quite fragile as the knobs on them seem quite liable to breaking. Some sounds are at times a little tricky to hear such as the vibe.

All in all, one of the least interesting and bland multi-modulation pedals out there. For a bit more money a Line 6 M5 would provide more odd ball and better common modulation effects along with reverbs and delays.

Neat little box o' tricks

This pedal serves as my main flanger/phaser pedal but it features more than that. It also has a vintage and multi chorus; a vintage style vibe and (its USP) a step-phaser which stutters the signal based on the phaser setting. Great for live and studio uses!
