With original late-70s Op-Amp Big Muffs selling for exorbitant prices, Mike Matthews decided to take the power to the people and reissue the classic pedal at a price that players could afford! The circuitry of the new Op-Amp Big Muff —sometimes also referred to as the IC or V4 Big Muff— has been faithfully re-created while several practical enhancements have been added including a compact, die-cast chassis and true bypass switching.

“The Op-Amp Big Muff was popularized by the brilliant Billy Corgan who first used it on the Smashing Pumpkins’ epic 1993 album Siamese Dream. After he was videotaped playing and talking about the reissue, Billy stated: ‘The magic’s still in the box, I can still get what I’m looking for!’” - Mike Matthews

The pedal relies on op-amps rather than transistors and three gain stages rather than four, to create its signature sound. It’s a sound that’s been described by noted Big Muff collector and historian, Kit Rae, as: “a huge, crushing Big Muff sound with more crunch… great for grungy, wall-of-sound distortion, heavy rhythm playing and heavy leads.”

Quick Specs
- A faithful reissue of the original classic circa 1978
- Iconic sound and vibe that’s coveted by guitarists
- Controls for Tone, Sustain and Volume, plus a Tone Bypass switch.
- True bypass switching for maximum signal integrity in bypass mode
- Rugged, compact, die-cast package… pedalboard friendly
- Ships with a 9Volt battery, also accepts an optional EHX9.6DC-200 AC Adapter
- Dimensions in inches: 2.75 (w) x 4.5 (l) x 2.1 (h)
- Dimensions in mm: 70 (w) x 115 (l) x 54 (h)

This shop is a musicians dream. The staff are so friendly, helpful and really know their stuff. We first bought a flute and keyboard. These were beautiful instruments. The flute was a purple vivace III with a clear quality sound and was provided with all the cleaning materials. I love playing it and has rekindled our love of music. My husband also made the switch from an acoustic to electric guitar and got his dream of owning his own Gretsch. The prices are excellent for the quality you get and staff really look after you so the upkeep and after care is there for you as well. The best music shop in shop in Hull.

Apparantly in business for 156 years. It`s clear to me that to last that long that the business must be providing a service that not only reaps a good living but at the same time puts a smile on the faces of so many customers. I`m in the process of having a huge clear out and after agreeing the sale of my piano, I pointed out that I had a drumkit that needed putting together and cleaning - left dormant in the garage for a few years- I was just about to put it in a skip I`ve hired but Alan said it may be ideal for a young kid as a starter instrument. What a lovely thought. Getting kids to have an interest in life that may just help them to stay away from video games. Also, the lads that came to take the piano away were very nice and polite. A business that is a credit to Hull

I would highly recommend, I received a friendly welcome and nothing was too much trouble. I was looking to purchase a full size piano keyboard to replace a standing piano and I was shown various options with great information to help me make an informed decision. There was no hard sell and I feel I came away with the exact thing I was looking for. Thank you, 10/10

Purchased a lovely Tanglewood electro acoustic guitar yesterday 25/3/25 from the Hull store, to enable my progression in guitar playing. Shaun who helped me was a lovely guy, informative, funny and knowledgeable, he listened to my requirements and ensured the guitar was suitable and what I required. All in all a great shopping experience, with a Billy Joel song played on the piano at my request (Shaun plays piano). Will definitely return. Thanks Shaun.

Left with a lovely 1/2-size guitar, case and beginner book for our daughter. She even got a blast of Happy Birthday on the piano. This is a lovely shop with amazing staff. Have walked into other music shops and been ignored, but not here. I will be back soon when it's time for me to buy a new electric guitar, even though it's a journey for us.
