Legendary Tones - 100 Watt Marshall Super Lead

legendarytones.com

The Marshall Super Lead 100-Watt Head is heralded as the quintessential amplifier for iconic rock tones, revered by legends like Hendrix and Page. Its simple, hand-wired design and dynamic distortion characteristics make it a staple for achieving classic soundscapes. However, its lack of pre-amp or gain control requires ear-splitting volumes to unlock its full potential, limiting its practicality in today's volume-conscious environments. Despite this, its historical significance and tonal prowess still make it a coveted piece for those who can accommodate its demands.

An OK-sounding vintage amp.

Let's face it: You can never quite go wrong with a Marshall since it's been the quintessential rock tone for what, 50-60 years now? This particular amp would be great if it wasn't for the outdated design, though. It looks and sounds good, but has only one measly channel. In order to push any drive out of it, you have to crank it all the way up to 11 and this motherfucker LOUD! There's no way a sane person would use it live without reamping it.

In a nutshell: The vintage points are cool and it's hot crunch sounds great in the studio, but there are a tons of newer amps that are capable of doing the same thing without bursting an eardrum.

ummm, a superlead has 2 channels, normal and bright? I've owned many, used to be my amp of choice when I played big venues, definitely 2 channels, split cathodes into a mixer gain stage, shared cathode follower tweed bassman EQ and then into the power section. do you mean it doesn't have independent EQ? Its just for fien tailoring, this is an amp where you start with everything but presence at 10 and turn down from there until it sounds right in the room you're playing.

its really loud, yes, but in a 500+ seat venue you don't even need any attenuation, its just enough level where you don't need to waste floor wedge headroom on your own guitar sound and you can have it full of kick, snare and bass guitar

its a specific tool for a specific job.... I got rid of my superleads because in my current situation, even with a little hotplate attenuation, the rooms they would be in are so small that any living thing standing directly in line with the cab will evaporate into the atmosphere as plasma... but in a big space where the sound can diffuse and there's a few hundred tightly packed bodies absorbing up the high frequency reflections? not that loud.... I would also debate that there are master volume amps that cop the sound.... I've heard close but the feel is never there and if you DO wanna turn up in a big space then you lose something because of all the extra preamp gain. Some of the Soldano's get close to a JMP version and the bogner stuff gets plexi-ish in the right mode or whatever, but this is one of those eleusive sounds, especially because every superlead sounds different. I've never used 2 that sounded the same. I ahd 4 of them in the studio at once and every single one was very different whereas an 800, 900 or a 90 Laney is pretty consistent amp to amp even with different tubes and biasing.

also, you can rebias this amp (and almost any other EL34 amp that runs 700v or less plate voltage) for JJ's very robust 6V6es and run it at 1/2 impedance to make it a fire breathing 30 watter. I've tried this toconvert one of my 50 waters into a 15 watt head for home recording with great results. Its an easy, non-destructive mod.
