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!"

The pedal relies on op-amps rather than transistors and three gain stages rather than four, to create its signature sound. Its a sound thats 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."

Features:
• A faithful reissue of the original classic circa 1978
• Iconic sound and vibe thats 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 fuzz gives a great Siamese dream tone, which I have struggled to obtain. I have had several distortion pedals in my collection (fender mtg:la, boss blues driver, boss ds-1 distortion, boss super distortion, Ibanez tube screamer), but never a fuzz pedal. Luckily, I don’t have to get another fuzz pedal because I have found the holy grail. I highly recommend this pedal.

Put an overdrive like the Boss SD1 or Earthquaker Plumes in front of this pedal and watch the magic happen! Use the OP amp setting and start with this pedal at 12 o'clock on all dials and turn to suit your taste. Well worth the money! Use your overdrive to boost and tighten mids slightly. Wonderful sound! Always keep going back to it as one of my main pedal board distortions.

Great sounding re-issue of an iconic fuzz pedal. Finally the fuzz sound i’ve been looking for without having to hunt down expensive vintage op-amp versions. It’s smaller pedalboard friendly footprint is a vast improvement of the original while retaining it’s vintage-core sound. As far as the price goes, you can’t go wrong. 4.8/5.0

This pedal sounds great, is affordable, and fits on even the smallest pedal board. This thing generates an astounding wall of noise on its own, and it only gets better if you stack a compressor or drive (or both) in front of it.

This is the dirtiest pedal I've ever played through. It sounds like the 90's stopped by for a jam every time I plug this thing in.c

Amazing, thick fuzz that really cuts through the mix. It's the sound I've been looking for for so long. Billy Corgan used one on Siamese Dream and this is the reissue. It sounds so much better than a regular Big Muff in my opinion. If you're looking to create a wall of sound, then you should buy this pedal.

Performance Warranty Banner

Protect your investment with the Long & McQuade Performance Warranty

A warranty can be a very important factor when making a buying decision. Because repairs can be very expensive in terms of parts and labour costs, manufacturers usually only provide one year limited warranties that generally only cover items that malfunction due to a manufacturer’s defect. With an important purchase such as a musical
instrument or piece of studio gear, however, many people want to have the peace of mind in knowing that their investment will be protected should the product no longer be performing at 100%.

Because of this, Long & McQuade provides our customers with a FREE one-year Performance Warranty on most of our products. The Long & McQuade Performance Warranty supplements the manufacturer’s warranty to ensure that our customers receive complete “no hassle” warranty coverage within their first year.

How does the Long & McQuade Performance Warranty differ from most manufacturers' warranties?
  • Performance Guarantee: Normal wear and tear is covered, so your product will be performing as well as the day you purchased it for the entire duration of the coverage. Band and Orchestral Performance Warranty does not include replacing pads or cleaning for woodwind instruments, unless deemed necessary by our repair staff. Ultrasonic cleaning for brass instruments will be provided if deemed necessary by our repair staff, but is not routinely offered under the Performance Warranty.
  • Product Replacement: If your product cannot be fixed or costs too much to fix, we will replace it with the equivalent model for no additional charge. If this is not possible, a full refund will be provided.
  • No Lemon Policy: Your product will be replaced should the same problem occur multiple times.
  • Convenient: Easy drop off and pick up of the product at any Long & McQuade location.
  • Guitar Setup: Guitars purchased at Long & McQuade come with 1 free setup, to be redeemed within 1 year for new guitars and 90 days for used guitars.
  • Loaners Available: A loaner product may be given while the product is being repaired.
  • Power Surge Protection: Your product is covered even if damaged from a power surge.
  • Accessory Coverage: Any peripheral devices or accessories that come with your product (i.e. foot pedal, case) are also covered.
  • Commercial Use Coverage: Music and recording professionals who purchase gear for “heavy-use” commercial purposes will still be covered.
 

Long & McQuade reserves the right to restrict the purchase of additional years of Performance Warranty. Used products come with a 3-month Long & McQuade Performance Warranty. Some products (i.e. computers, software, cymbals and other items) are covered only by the manufacturer‘s warranty. Consumables (i.e. strings, reeds, drum sticks, batteries, tubes, cross faders) are excluded as they are designed to be replaced. Cosmetic Damage, Accidental Damage, or problems caused by Humidity or Temperature Issues are not covered. Speakers damaged by overpowering are generally not covered. Our coverage does not provide compensation for loss of use. As of June 2018 the Performance Warranty is no longer transferable. The warranty is only valid in Canada.

Purchasing additional years of coverage

Some manufacturers provide warranties for longer than 1 year; however, these are usually limited warranties that do not provide the same coverage as the Long & McQuade Performance Warranty. Customers interested in more complete and convenient (but not necessarily longer) coverage are still able to purchase additional years of the Performance Warranty.

If you are interested in receiving this coverage for longer than one year, you have the option of purchasing additional years of the Performance Warranty. The pricing is as follows:

  • NEW products: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
  • USED products: 4% of the current new selling price to increase the warranty from 3 months to 1 year. 4% for each additional year.
  • GUITARS: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year. $45 maximum. An additional free setup is not included with additional purchased years of Performance Warranty.
  • BAND and ORCHESTRAL instruments: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
