I really like my Plexitone, but I don't know I'd call it a Marshall in a boxIf you have an amp with strong mids look no further than the Carl Martin Plexitone. It´s the reigning champ of hot-rodded Marshall tones in a box.
+1 for the Jackhammer. It is more or less the spiritual successor to the Shredmaster. Guitartoneoverload.com did a comparison video you can check out. The pedal is very bass-heavy but can be adjusted. The overdrive setting is very useful and has hi-gain - the distortion setting is a little muddy and hard to use.Marshall Jackhammer does a good take on the high gain Marshall sound. And it's dirt cheap too.
This should be a stickyDistortion is like barbeque sauce. They are almost all good, but you have gotta actually try them yourself to see which one you prefer.
I haven't heard the Jackhammer, but what you described above made me sell the Shredmaster.The pedal is very bass-heavy but can be adjusted. The overdrive setting is very useful and has hi-gain - the distortion setting is a little muddy and hard to use.
I never thought of the Riot as an amp-like pedal. High gain distortion for an already fine tube amp, but the pedal itself didn't make me think Marshall. The Reeza is wonderful, but I've only tried the old one. The original Guv'nor is my favorite, but might not be enough gain for you by itself so I submit the Hermida Tiki Drive as my favorite high gain Marshall-esque box.I'm looking for something that can do an over the top, high gain Marshall crunch ala Jonny Greenwood and his Shredmaster. I'm considering the Suhr Riot, Emma Reezafratzitz, Crunch Box, and Box of Metal as now. Any input would be appreciated. Thanks!
