Carrying a full stack up a flight of stairs for a small show gets old fast. The EVH 5150III LBXII is built to put a stop to that, the same high-gain 5150 voice in a head light enough to grab with one hand.
It’s a 15-watt tube head, but it doesn’t feel stripped down. Two footswitchable channels, an effects loop, and a 1/4 power switch mean you give up very little by going small.
This one is aimed at hard rock and metal players who want real saturation with almost no gear to haul. Home players chasing 5150 grind at quieter volumes have plenty to like too.
We leaned on it hard to see what that small box gives up. The sound and feel are up next.
EVH 5150III LBXII 15-watt Tube Head
A 15-watt, two-channel tube head for gigging metal and hard-rock players who want portable 5150 gain.
Pros
- Authentic 5150 high-gain tone in a tiny head
- Two footswitchable channels, cleans to saturated leads
- 1/4 power switch tames volume for home use
- Effects loop keeps delay and reverb clean
Cons
- Needs a separate speaker cabinet to play
- High-gain voicing is specialized, not all-genre
Sound and Playability
The LBXII is a two-channel amp, and the two channels couldn’t be more different in character. Channel one is the clean channel, and it stays glassy and full even when you push the gain into a light crunch.
Channel two is where the 5150 reputation lives: a thick, saturated high-gain voice with tight low end and the kind of singing sustain that made the original 5150 a metal and hard-rock staple. Rolling between the two with the footswitch is seamless, so you can keep a clean verse and a roaring chorus on tap without touching the amp.
What makes the LBXII genuinely useful at home and on stage is how the gain feels under the fingers. Even at lower volumes the high-gain channel keeps its grind and doesn’t turn flubby, and the clean channel responds well to your picking dynamics and guitar volume knob.
A small tube amp like this earns its keep when it sounds like a real valve amp at every volume, and the LBXII does exactly that.
Build and Features
This is a 15-watt tube head built around a heavy-gauge steel chassis, and it feels like a road-ready piece of gear rather than a toy. The lunchbox form factor is the whole point: it’s light enough to drop into a backpack or carry next to your guitar case, which is a relief if you’ve ever hauled a heavy guitar amp up a flight of stairs to a gig.
The feature set is focused and practical:
- Two channels with footswitchable clean and high-gain voicings
- 1/4 power switch to drop the wattage for quieter practice
- Built-in effects loop for time-based pedals like delay and reverb
- 3-band EQ with presence and resonance controls
- Heavy-gauge steel construction for the road
The effects loop is the detail gigging players will appreciate most. Running delay and reverb through the loop instead of in front of the high-gain channel keeps those effects clean and clear, which matters a lot once you’re pushing real saturation.
Who It Is For
The LBXII is aimed squarely at the player who wants serious high-gain tone without a serious amount of gear to move. If you gig regularly, play hard rock or metal, and want a backup or grab-and-go head that still sounds like a full-sized amp, this is built for you.
It’s also a smart pick for the home player who wants authentic 5150 gain but needs the 1/4 power switch to keep the volume neighbor-friendly.
It’s less ideal if you want an all-in-one solution out of the box. This is a head, so you’ll need a speaker cabinet to run it, and players chasing pristine pedal-platform cleans across a wide range of genres may want something more neutral.
But for anyone shopping for an electric guitar rig built around heavy tones, the LBXII covers the core ground beautifully.
Frequently Asked Questions
Is the EVH 5150III LBXII loud enough to gig with?
Yes. Fifteen watts of tube power paired with the right speaker cabinet is plenty for small and medium venues, and it holds up in a band mix without struggling.
For larger stages you’d typically mic it through the PA, which is standard practice for an amp this size.
Does the EVH 5150III LBXII need a speaker cabinet?
Yes. The LBXII is an amplifier head with no built-in speaker, so you need to connect it to a separate guitar speaker cabinet to make sound.
Match the cabinet impedance to the amp and you’re ready to play.
What does the 1/4 power switch do?
The 1/4 power switch drops the amp’s output power, which lets you reach that sweet spot of tube saturation at a much lower volume. It’s what makes the LBXII practical for bedroom and apartment practice while still delivering the same core tone you get on stage.
Is the EVH 5150III LBXII good for metal?
Absolutely. The high-gain channel is voiced for exactly this, with tight low end, plenty of saturation, and long sustain.
It handles modern metal, hard rock, and high-gain lead work with ease, which is why the 5150 name carries so much weight with heavy players.
Final Thoughts
The EVH 5150III LBXII is one of the easiest ways to get genuine 5150 tube tone without committing to a full stack. Its two channels span clean to high-gain, the 1/4 power switch keeps it usable at home, and the effects loop and steel chassis make it ready for the road.
The only real catch is that you’ll need a speaker cabinet to go with it.
If you’re a gigging guitarist who wants big high-gain tone in a head you can carry one-handed, this is the lunchbox amp we recommend. Check Price on Amazon
