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.

- 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)

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.

Brilliant service and helpful staff. I had planned on getting a nylon stringed guitar for a while and was struggling to find one. The staff here helped massively and offered me (without me even asking) if I was interested in playing. 10/10 definitely going back when I look into my next Investment.

Exceptional Guitar Buying Experience – Highly Recommended! I recently purchased a Gretsch G5122 Electromatic from Gough & Davy, and I couldn’t be happier with my experience! From start to finish, everything was absolutely perfect. 🚚 Super Fast & Secure Delivery The guitar was shipped via FedEx and arrived incredibly fast. The packaging was beyond impressive—so secure that you could probably drop a nuke on it, and the guitar would still be intact! 🤯 Top-notch protection and care in shipping, which is rare these days. 🎸 The Guitar – Stunning Quality! Even though it was sold as second-hand, the condition is practically mint—I was honestly shocked at how perfect it looks and feels. This was my first experience with a Gretsch, and I can confidently say it was money well spent. The tone is absolutely amazing, and the craftsmanship is outstanding. 💬 Customer Service – Smooth & Professional From the moment I placed my order to the moment it arrived, the process was easy, hassle-free, and professional. The team at Gough & Davy clearly values their customers and ensures that every step of the buying process is smooth and enjoyable. ⭐️ Final Thoughts This shop deserves more attention and more customers! I can say without hesitation that Gough & Davy has gained a loyal customer for life. If you're looking for a reliable, professional, and passionate music store, look no further. Big thank you to the team – I’ll definitely be back for more! 🎶🎸🔥
