Featuring an internal 36V of headroom for authentic tube-like tone and response, the Walpurgis is a JFET based emulation of the preamp section of a late ‘60s Laney Supergroup amplifier with the Worship Knob controlling the wet / dry blend of a modified Dallas Rangemaster boost.
Harness Tony Iommi’s iconic guitar tones from the 60’s, 70’s, and beyond with the turn of a single knob.
The Walpurgis can be used as an overdrive pedal into the front end of your amplifier or turn up the internal master volume trim pot to boost the output and run it as a preamp into your effects return or dedicated power amp.
Worship: Controls the wet/dry blend of the Rangemaster Boost into the Laney Supergroup Preamp. Set it at minimum to remove the boost entirely.
Use only a standard 9v DC power supply with a 2.1mm negative-center barrel. An isolated power supply is recommended. Power supply not included.
- One-knob Iommic Overdrive / Preamp for guitar and bass

I’ve played through many Iommi inspired pedals that utilize the Laney Supergroup+Dallas Rangemaster combo with very mixed results until now. Having played through actual Laney Supergroup amps with numerous Rangemaster style clones none of those other pedals really came close, but this one just nails it!

I have been playing around with it and man! This pedal really does sound like Tony’s tone! Especially going directly in to my audio interface with that new Laney IR cab from Two-Notes with the power amp emulation enabled. It also sounds good going into the clean channel on my Orange CR120H as well. Been playing some Sabbath riffs and It inspired me to come up with some new riffs of my own. I love the tube like response a lot. I have tried other pedals like the Fuzzcoven, Hypercoven and Fuzzlord’s Drone Master in front of it with the worship settings set min and just love how it fuzzes! This pedal has been a blast so far!

10/10 My favorite pedal! I have been chasing Iommi’s tone for a very long time trying a multitude of different pedals that left me unsatisfied. This pedal absolutely crushes Sabbath tone and keeps it simple with a single knob. I highly recommend this to anyone that wants to take their tone to the next level!

This thing really delivers; it’s one of my favorite pedals I’ve ever purchased. I’ve tried a handful of other pedals that are based on amp circuits, but this one really feels like you’re playing a tube amp amp. The Sabbath tones are great and nearly sound right off the record. Cranking the knob all the way up delivers an incredible high-gain tone. Must have pedal

Instant riffage inspirado with this one! Started out with some Sabbath riffs, but soon ventured on writing stuff with this sound in mind! Andxthat was initial try-out session! The OD/boost combo is finely tuned and gnarly as hell, not only fir Iommiesque stuff! Great pedal!

Became my favorite pedal on the first session. I assumed it would be decent and worth a purchase, but was surprised how actually awesome this thing is. It’s exactly what I was always wished I had to quickly hit the perfect sabbath sound. Love the one knob too. Hell yes Steve !!

If you want to go the real way in a true Iommi tone. You need to get one of these. The Walpurgis is a great great thing, even it work amazing going into the front end of a Solid State amp (like an Orange CR120H) Also it rules as for quality of construction, art, etc, etc…

It’s a blessing from St. Anthony himself. An amazing sabbath tone and it makes my little bedroom rig sound monstrous.

This is my fave Iommi flavored pedal period. I own the others, we all know what they are :), and while those are fine pedals this is simply spot on and waaay closer to his sound. Like plug in and instantly your riffs sound like TI. Crazy good pedal.
Oscar Matthews (verified owner) –
Excellent pedal. Tried the Sabbra Cadabra and the TI Boost and this beats them both by a country mile. For a one knob pedal the versatility is ridiculous and the overdrive flavours available by using different amps is insane.

One of the best if not the best one knob tone circuit available. This pedal really surprised me with the responsiveness. I did have to run it slightly hotter than the recommended setting but that could just be from my signal chain. 490’s to a Hilbish (Beta Lead Clone) to a PPC 412. Again excellent pedal, excellent tones and a great value.
Honestly, the Walpurgis is my favorite pedal right now. Perfect for sabbath sounds but also very good for other vintage distortion tones. It does a great motörhead sound!
Jered (Beholden to the Riff) –
The Walpurgis is a tone factory! Warm, tube-like saturation ranging from slight vintage amp breakup to MONSTROUS amounts of distortion -Absolute BEAST of a pedal!
It’s incredible how they’ve managed to get Iommi’s tones throughout the years in this pedal, this is definitely one of my top favorite pedals of all time now. I use it as a preamp with some of my other Fuzzes. Sounds amazing with the Fuzzcoven, too. I had to get the t-shirt too, it’s just that cool.

You want that vintage Tony Iommi sound in a single knob pedal, then look no further than the Walpurgis. When I received it, I couldn’t stop playing. Excellent jamming sound. I was playing along to the early Sabbath songs, and this pedal sounds exactly like Tony’s tone, I was really jaw dropping impressed. I tend to favor the lowest and 9 O’ clock settings because I favor Tony’s tone on the debut album and Paranoid. I am enjoying the hell out of this pedal, thanks Steve.

Anthony from Ampturco Guitar Werks. This pedal is by far one of my all time favorite pedals ever. This has easily put the tone in my head right to my speakers. It’s not only fantastic at giving you iommic style tones but it’s a great flavor to add to your already killer personal tone. This does exactly what I was hoping for. It adds the texture of that incredible Laney Supergroup and the Rangemaster on top. Eq wise I really like how it doesn’t get overly dark as you work your way up the knob. It maintains the perfect amount of treble and really allows you to cut through the mix without being harsh. If you are a fan of Iommi and play the guitar this is an absolute must have pedal. It has become my always on pedal. Does it Doom and Team did a fantastic job here.

Some of the sounds I’ve wanted since my teenage years are finally mine. This pedal gives me some of the most desired and most iconic guitar tones ever recorded and I couldn’t be happier to have this amazing pedal in my arsenal. Does It Doom hits it out of the park once again. A+
This pedal is as Iommi as it gets. I thought I had the sound nailed with my setup, until I got this. I’ve been chasing this tone since I first heard paranoid. Fucking incredible.

This pedal is amazing. Even though it’s one knob, the range is incredible. I am actually shocked. So happy I took a chance on this!

The Walpurgis is now my go to pedal for leads and riffs! I put in the middle for that Vol 4/Master of Reality tone. Cuts through the mix perfectly. And it looks rad in purple!
John Pio Shadow of Jupiter (verified owner) –
I bought it as a gift for our guitarist, so I can’t speak from a personal usage standpoint, but all I can say is we’ve written the most killer stuff of our lives since Walpurgis has been on the pedal board. Just sayin’.
Marc P –
Great pedal, love the single knob design. Press the knob and your sounding like early Toni Iommi. Playing on humbuckers sounds good, but pairing this pedal up with a P90 is the way to go.
Jerred (verified owner) –
100% Iommi right when you plug in. All of Sabbath’s tone with just a slight turn of the knob and it delivers a killer attack when you bust out the ol’ Sabbath solos! Big fan of this pedal! Using this pedal with a pair of p90 pickups is absolutely wicked good!
Jason (verified owner) –
Love this one knob Iommic life in a pedal! Really cool tone options just from the one knob! Also, it looks really freaking cool!

Fantastic pedal! A friend bought this pedal first. When I heard his pedal, I had to get one for my own! After I got mine, another friend heard it and then he went out and got one too! Between us we have the first, second and third iterations of the Walpurgis. All versions look great, and of course they all sound great!
The Walpurgis Iommic Overdrive is a fantastic pedal. I run my Epiphone SG into a practice amp and the Walpurgis makes it seem like its like Tony’s rig but simplified. It’s a gift almost from the Iron Man himself, Lord Iommi. Steve from Does it Doom really knows his stuff !!!!
ChristopherK (verified owner) –
Killer pedal! …has been on my board since day one – Adds clarity, cut, and “oomph” to my my base tone, running it in parallel with some other less controlled dirt. 🤘💥❤
Joe (verified owner) –
High quality and sounds great. I have an Epiphone SG Pro and run the pedal into a Marshall DSL40C. Great Sabbath tones with one knob. What isn’t there to like? Upon first playing it I was a little confused because I wasn’t getting much volume. Then I remembered the internal volume switch. A little tweaking of that and POW! Right in the kisser. And the case candy was awesome. I have the Catalinbread Sabbra Cadabra and this is replacing it.

Black Sabbath Vol 4 is my favorite sabbath album. I absolutely had to have the vol4 version of walpurgis. I love the stickers it came with as well.
Brian Falcone –
I dig this pedal a ton. My only gripe with it is that it is too bright. If I use it on a clean amp I have to dump most of the treble to get a useable sound. But through a single channel high gain amp. This thing crushes! The Walpurgis is currently my all time favorite overdrive to push an amp. Also…Customer service at does it doom is incredible. I contacted them with a question and I had a reply within minutes. Thanks again!
The Walpurgis Iommic Overdrive Preamp is awesome. As soon as I plugged it in to my Marshall DSL20 and hit a couple Sabbath chords on my custom guitar with just an old DiMarzio DP151 PAF Pro in the bridge and a volume knob the tone was there straight away.
I love the ease of ease and variety of tone as you turn the dial and it’s not a one trick pedal just to sound like the Master Iommi either. I have quite a few pedals but am still new to figuring out what plays well together and in what order.
Very happy with the quality and look of the pedal and Steve @ Does it Doom provides great customer service and quick helpful answers to questions. Highly recommend his products!!

This pedal truly nails Iommi’s tone. I’ve chased Sabbath tone for many years with mixed results. This pedal is a must have!

It does exactly what it sets out to do. I think it sounds great. It gives you that trouble boost sound without a doubt and that Laney tone too.
