Distortion with Weight and Girth

Based on the formidable high-gain tone of the VH4 tube amplifier, the Diezel VH4-2 pedal delivers all the high-intensity distortion you can handle. With two switchable channels voiced for rhythm and lead tones, the VH4-2 pedal starts with wide-ranging controls for Gain, Treble, Middle, and Bass. From there, you'll be able to explore a vast soundscape with the Presence, Deep, and Master controls, shaping low-end girth and midrange bite for just the right amount of sonic intimidation. Essentially, the Diezel VH4-2 pedal puts one of the most revered metal amplifiers on your pedalboard.

Based on one of the most popular modern metal amps

First unleashed in 1992, the Diezel VH4-2 is a KT77-powered tube amp with a reputation for exceptional metal tone. You can hear it on recordings by Metallica, Korn, Tool, Staind, and other modern metal pioneers. The amp's four channels ranged from sparkling clean to ultra-high gain — the VH4-2 pedal emulates channel three, or the Mega channel. This is the channel most metal players gravitate toward, offering startling high-gain intensity and immense sonic girth. The VH4-2 allows you to switch between two voicings for rhythm and lead roles, each with its own gain and master volume controls.

Deep, Presence, and Master controls deliver amp-like control over your tone

At the heart of the VH4-2 pedal's character is its Deep (resonance) control. Active in the final output stage of the pedal, the Deep knob allows you to fine-tune your tone's low-end punch in a way you can't achieve with traditional EQ or tone controls. The Presence control helps you find just the right amount of bite to cut through a mix without making your signal too harsh.

Premium build quality for sonic integrity and long-term reliability

At Sweetwater, we've helped countless musicians prepare for world tours, and we can confirm the Diezel VH4-2 pedal is ready for the ordeal. Its metal construction is lightweight yet rugged. Discrete circuitry (instead of an integrated circuit) maximizes sonic integrity. And its included universal 12-volt power supply delivers stable power anywhere in the world. And considering that it packs the VH4-2's Mega channel into a convenient stompbox, the VH4-2 pedal effectively allows you to travel with an additional amplifier.

Reviews

The king of distortion pedals
I've tried SO many pedals over the years to get that killer sound I've been trying to find. I wish I would have found this VH4-2 sooner because it's straight up amazing. Diezel did a fantastic job on this one. This is the only pedal I'll run in addition to my Helix (because their model just isn't the same). It's not just a stomp box that kinda sounds like the amp it's derived from if you tweak it *juuuust* right. No, it REALLY sounds like it. I have it going into the clean channel of my Mesa/Boogie Mark V:35, which I prefer over running it through my effects loop. Coming out of a Rectifier 2x12 vert cab. It really screams when paired with some hot pickups. My favorite pairing so far is with my Vulture that has a EMG Het Set.

However, my sales engineer Felipe has been amazing with helping me find all sorts of gear! I'm telling y'all, you gotta snag this one. Worth every penny. You won't regret it.

This pedal is a Monster
This pedal chugs, a little dark but hey the sound is superb, have TONS of gain and other features that allow any type of fuzz, distortion, etc This pedal is a monster, if you are into Heavy Metal, Death Metal, Nu Metal, Thrash Metal this is your pedal, don't look elsewhere.

Clean, Crisp Distortion
Great pedal! It provides very clean, well defined distortion with a ton of gain. Sounds like it's doing come compression on the lower frequencies too so you can get it to chug and it's not over powering, and you can hear individual notes in chords even at full gain. Very reminiscent of 90s Metallica, and/or Adam Jones from TOOLs tone.
lives up to the hype
This thing turns my AC30 into something worthy of he heaviest of riffing. I like to play all kinds of music, and run the AC30 in stereo with a Mesa Mark V, getting this has allowed me to really get into some chugging, and still enjoy the lovely cleans of the Vox when it is not on.
Face Melting Gain at the push of a button
There's a reason this thing is switched on 90% of the time, it's the ultimate metal distortion sound in the form of a pedal. If you're looking for a powerful metal guitar sound, look no further.

The only complaint I have is just a nit-pick, but the LEDs on this thing are like lasers being shined directly into your eyes, but it's nothing a bit of painters tape can't fix.
