Ace Tone FM-2

The BOSS OD-1, a legendary pedal that continues to captivate guitarists worldwide. This time, we'll focus on the particularly popular early model, the "Silver Screw" version.TCGAKKIEffectorSano, the person in charge, will explain its profound appeal and the evolution of its meticulously detailed specifications.

It possesses a unique presence that sets it apart from later overdrive pedals, and it continues to receive high praise from both players and collectors to this day. It is one of my absolute favorite BOSS pedals, and I have always wanted to feature it. I recently had the opportunity to acquire many OD-1s from customers, which led to the writing of this column.

Furthermore, differences in specifications depending on the manufacturing year, and variations in the installed components (especially the operational amplifiers), can result in different sound characteristics. This is also the reason why the OD-1 continues to be a special product.

Furthermore, it lacks tone control, and only has two knobs: LEVEL and OVER DRIVE.This straightforwardness also symbolizes the philosophy behind the OD-1.Rather than completing the sound creation process solely on the pedal, the essence of the OD-1 lies in creating distortion that is perfected within the overall balance that includes the guitar amp and playing style.I believe that is its greatest appeal.

From here onTCGAKKILet's take a closer look at the subtle differences in specifications from a unique perspective!

We've lined up a whole array of models from 1977 (#6400) to 1979 (#8900)!!

While the thickness of the INPUT/OUTPUT markings can vary depending on the period, there doesn't seem to be any significant difference in appearance between different eras for the silver-screw OD-1. Note that in the black-screw era, the hyphen in "OD-1" becomes extremely short.

There is a stamp inside the pedal section (inside the battery compartment).
The center stamp serial numbers go up to #6400.
It appears that the stamp serial number will be placed on the right side starting from #6500.

• Up to #6400: Center stamp serial number
• Starting with #6500: The stamp serial number will be printed on the right side.

• Early models: External spring type, commonly known as the "skeleton switch"
• #8600 and later: Changed to a black switch with internal screws.

InitiallyIt originally came in a relatively sturdy cardboard box. The exact timing is unclear, but later it was changed to a cardboard box with a plastic coating.

Next up is a topic I know you all love: operational amplifiers.

The following is based on the lack of official documentation.Records from actual machines that have been in stock at our store in the past.This is the result. Broadly speaking,It is classified into the "Quad Type Period" and the "Dual Type Period".

Some people might feel that the OD-1's sound isn't particularly flashy compared to modern pedals.

However, when actually placed before a tube amplifier like a Marshall and used as a booster with a crunch to clean tone, its true value becomes clearly apparent.This is why many professional guitarists continue to include it on their pedalboards even today.

• When driven, the bass doesn't become excessively bloated.
• The midrange has a natural, forward presence, and the high frequencies come forward while maintaining their roundness.
• When playing chords, the sound doesn't become muddy or clumpy; single notes have a thick core, but are never too harsh.

The OD-1 from the silver screw era, in particular, seems to retain its tonal definition even when the distortion level is increased, adding a sense of drive while preserving the amplifier's original character.

As mentioned earlier, its response when used as a booster is also excellent, precisely pinpointing the point where the amp distorts "one more level" in a pleasing way.It really delivers. This goes beyond being just a distortion pedal; it almost seems designed as an instrument to push the amplifier's potential to its absolute limits.

The BOSS OD-1 is the origin of the overdrive genre, and even by today's standards, it still holds unique value.

The silver-screwed models are quite different from the later, more user-friendly overdrives. They possess a simple yet raw, authentic quality, and a certain vulnerability due to their unfinished nature, making them incredibly appealing.

The OD-1 is a vintage overdrive pedal with extremely musical characteristics, directly reflecting the player's touch and relationship with their equipment in the sound. I highly recommend it to those who haven't yet experienced it, and especially to younger generations.I hope you will feel it.

I personally prefer using it as a drive pedal, but it produces a sound that works well for everything from 1970s and 1980s rock to hard rock. There are many different versions available, so comparing them is one of the joys of using it.

The reason the OD-1 continues to be talked about and sought after both in Japan and internationally is not just because of its specifications or its rarity, but perhaps because it's a pedal that directly teaches us the "joy of playing simply and authentically," something that modern people may have forgotten.
