The tonal requirements of my current Metal Project were beyond any stock, classic Marshall. I have other more modern amps, and have recently been looking at different high gain amps currently available. I have always been adverse to modding any of my classic Marshalls. Not because I am some kind of stock-purist, but because what I have seen historically is guys just adding another 12ax7 and additional sizzle and gain to the Marshall. Sure, after these mods there’s more sustain, and smooth distortion... but the trade-off is crap because the Marshall aggression, transient response, and percussive “thwack” is lost.
After Jens took in my 6505+ for his supercharge mod, and we spoke about my tonal goals, he suggested that I mod one of my old JCM 800s.
I was hesitant. Having just met him, I figured he would just offer some typical overly saturated Marshall mod.
I told Jens, “Listen, the LAST thing I want is creamy distortion that is easy to play. I don’t want my crunchy JCM turned into a squishy, saturated Boogie, Mark III. NO, I want the speakers in my 4x4 cab to jolt like they were hit with a cattle-prod every time I spank the strings. I want my low strings to become some unholy combination of bass piano strings and a kennel filled with attack dogs. I want to hear every pick glitch, every mistake ringing thru. I need a tone that will send my right hand back to the woodshed with a metronome. Sure, I need more gain, and I need a wider frequency profile, especially deeper, tight, low end -but if more gain comes at the expense of tightness, percussive punch, and clarity, forget it. I wanna play minor +9 chords and hear every note singing. I do not want any mud, squish, or cheap forgiveness.”
If I was gonna let an amp guy dig into my vintage Marshalls, then I wanted him to understand that I want an UBER Marshall:
• one quarter Plexi,
• one quarter JCM 800
• one quarter nascar.
• one quarter 50 caliber rifle!
Jens said, “YES, YES. This is what I like! This is what I do! I will not bury your amp in compression and indirect circuitry. I will unleash your Marshall. I will not give it gainy-horsepower... I will give it IMMEDIATE-TORQUE!!! This amp is simple, and direct. That is its beauty. I will just further open it up. I will get rid of compression, and let ALL of it’s power hit the speakers.”
Then he offered a disclaimer, “I must warn you, most guitarists do not know what to do with an amp like this.”
I asked, “How soon can you start?”
I know my 4x12 gets anxious when I set this head on top. This amp is BRUTAL.
Testimonial by Andrew Bojanic - Producer/Writer Los Angeles, CA:
Hey Jens, just wanted to say that my 1982 JCM800 with the Kruse Gain Stage sounds f&%$ing awesome. With the Gain Stage off the tone is much more dynamic, open and clearer than before and with the Gain Stage ON it is "rocking" and I'll be able to use it on Hard Rock projects now as well as the more overdriven classic vibes.
Thank you great job !
