Marshall Spinal Tap Custom 410H Amp Head - This one goes to 11! 2025

This one goes to 11! For your consideration is the very limited run Marshall Custom 410H Spinal Tap Collaboration Amp Head. 20 made, only 11 sold & released into the hands of collectors, this was serial #2 (serial #1 was kept by the Marshall curators).

A rare beast indeed in this supercharged JVM410H, a 100-watt tube head that Marshall and Spinal Tap proudly tout as “the loudest amp ever made,” and for good reason — the Master Output control goes to infinity.

Of course, every other knob goes to 11, and the original amp’s 001 and 002 channels are renamed as Tufnel and (David) St. Hubbins modes. Yet, the homage honors more than one of rock’s greatest bits and players, as every bass-frequency control knob is labeled “Smalls” in honor of the band’s original bassist, the late Viv Savage.

Item Description

Introducing the Marshall Custom 410H Spinal Tap Collaboration Amp Head, available in an extremely limited run with eleven units sold exclusively on Sweetwater Gear Exchange. This is the loudest collaboration ever made, built on the spirit of the JVM410H and created to celebrate the moment in rock history when Marshall and Spinal Tap became forever linked. 

For forty years fans have joked about amps that go to eleven. Now, Gear Exchange made that moment real! 

This head captures the full absurdity, volume and rock and roll excess that defined Spinal Tap. All knobs go to 11. The master volumes reach infinity. The channels are renamed Saint Hubbins and Tufnel Mode. The bass control is labeled Smalls in honor of Derek Smalls. 

The custom panel brings the collaboration to life, and a bold Spinal Tap logo marks the back. Built for players, collectors and anyone who loves going too far, these are the first and only official Spinal Tap amplifiers ever produced. 

Features That Go Beyond Logical Volume Levels 
- All knobs go to 11 — because of course they do. 
- Dual Master Volumes that go to ∞ (infinity) — for when 11 still isn’t enough and you need to bend the laws of physics. 
- Bass control labeled “Smalls” — respectfully named after Derek Smalls, because nothing shakes a stadium like that low-end thunder. 
Two Channels: 
- Saint Hubbins – your bright, articulate, heavenly-crunch channel. 
- Tufnel Mode – darker, thicker, and capable of summoning the tone equivalent of getting lost backstage forever. 

Tech Specs for Serious Players (and unserious ones): 
- 100W all-tube power fueled by a quad of EL34s 
- ECC83/12AX7 preamp section for classic British gain 
- Custom-voiced Spinal Tap EQ curve built to handle both subtle nuance and full-stack absurdity 
- Built-in attenuation for taming the beast without sacrificing tone 
- 4/8/16Ω selectable output 
- Effects loop (true bypass) 
- Hand-wired construction for maximum durability when your tour manager says, “Just one more show…” 
- Authentic Marshall cabinet-matching circuitry 
- Custom all black case with the Spinal Tap logo on the front 

Limited. Loud. Legendary. 

This is your chance to own a piece of rock-and-roll history—part amplifier, part collectible, all attitude. 
Whether you’re a die-hard Spinal Tap fan, a Marshall purist, or just someone who enjoys turning things up far too loud, the Custom 410H “Spinal Tap” Edition is sure to impress.
