The story: from the first chorus pedal to the compact line
The first Boss pedal was not a compact at all. Launched in 1976, the CE-1 Chorus Ensemble was the world's first chorus effect pedal, released by Roland's new Boss division3. It was a large-format unit, and its chorus sound came from Roland's own designs: Boss later described the CE-1 as an iconic pedal whose rich, warm character still defines the brand's chorus tone4.
The compact pedal line followed in 1977, debuting with the OD-1 Overdrive3. With just two controls, Level and Overdrive, the OD-1 became, in Boss's own history of the brand, "one of the first pedals to truly emulate the sound of an overdriven amp"5. The 1977 debut brought three models, and Boss marks each first-of-its-type pedal with a "1" designation in its model numbering6.
The compact format grew quickly:
The compact line grew out of Boss's earliest pedals. The CE-1 Chorus Ensemble, launched in 1976, was the world's first chorus effect pedal and the very first Boss pedal34. The compact pedal line followed in 19773. The CE-2 then distilled the sound of the CE-1 into the smaller compact pedal format, tuned for mono operation and a lighter modulation sound than the CE-176. Boss later revisited this circuit in the CE-2W Chorus, a compact pedal built on the CE-1 and CE-2 chorus lineage67.
The compact line's longevity is unusual. Boss notes that over 140 unique models have been produced, over 19 million units sold, and many have remained in non-stop production for decades1. The DS-1 Distortion is, by Boss's account, the top-selling Boss compact pedal ever, with an original, unchanged design6. The format has even been adopted by other makers: Analog Man's OG-1 overdrive is an explicit tribute to the 1977 OD-18.
What Boss is known for: compact pedals, Waza Craft and MDP
Beyond the standard compacts, Boss's current range is organized around two signature ideas: the Waza Craft series and MDP processing91011.
Waza Craft
Boss describes Waza Craft as its special edition series: "In Japan, 'Waza' is the term for art and technique, and these special edition pedals proudly carry the Waza symbol to represent the pinnacle of BOSS design and craftsmanship"12. Every Waza Craft pedal features a mode switch for extended range10, and the series includes premium components throughout10.
The Waza Craft line covers several approaches:
| Pedal | What it is |
|---|---|
| SD-1W | Waza Craft edition of the SD-1 Super OverDrive, released 201459 |
| DM-2W | Revival of the discontinued 1984 DM-2 analog delay, with an expression pedal input for foot control of delay time13 |
| HM-2W | Special edition of the 1983 to 1991 HM-2 Heavy Metal distortion10 |
| DS-1W | Waza Craft edition of the DS-1 distortion1415 |
| FZ-1W | A modern interpretation of vintage fuzz, not a reproduction of a past design12 |
| TB-2W Tone Bender | A limited-run Tone Bender, developed after Boss explored and analyzed many vintage fuzz pedals12 |
| BP-1W | Analog booster and preamp with circuitry derived from the CE-1 Chorus Ensemble and RE-201 Space Echo preamps16 |
| VB-2W | Waza Craft vibrato, a revival of the VB-217 |
| DC-2W | Dimension effect pedal with all-analog audio circuitry18 |
The FZ-1W stands apart within the series: "Unlike previous Waza Craft models, the FZ-1W does not provide a reproduction of a past design. This pedal is our modern interpretation," Boss explains12.
MDP technology
MDP, or Multi-Dimensional Processing, is Boss's proprietary digital processing technology. Boss describes how it works: "In real time, MDP analyzes the various elements that make up the sound, including frequency, overtones, dynamics, pickup response, and playing characteristics such as note register, single notes vs. chords, bends, and vibrato amount, then processes each element in unique ways to produce optimized tones as you play"19.
Boss positions MDP as something analog circuits cannot do: the company says its MDP pedals and high-speed DSP "deliver a superior playing experience that's unattainable with analog"20. MDP appears across the range:
- DS-1X Distortion: digital, using high-speed DSP and MDP technology20
- OD-1X Overdrive: the MDP successor to the OD-1 name21
- BB-1X Driver: analyzes the bass signal in real time for optimized bass tones11
- CP-1X Compressor: powered by MDP, which Boss says provides compression that never overwhelms your instrument's character19
- BC-1X Bass Comp: MDP-based compression for bass22
- MD-500: a modulation pedal whose Overtone mode uses MDP to alter the input signal's pitch and harmonic characteristics23
- GT-1000: several amp types employ MDP24
Boss and Roland
Boss began as Roland's effects division and remains part of Roland: the CE-1 was released in 1976 by "Roland's new BOSS division"3. The two brands' designs cross over regularly. The BP-1W booster and preamp carries analog circuitry "derived from legendary BOSS and Roland effects, specifically the CE-1 Chorus Ensemble and RE-201 Space Echo preamps"16, and Boss's vocoder and synth pedals draw on its guitar synth technology162526. Boss's larger units, such as the GT-1000 multi-effects and the BCB-90X pedalboard, round out a range that spans single compacts, rack-style multi-effects and accessories27.

Questions
Who owns Boss pedals?
Boss is the effects division of Roland. The CE-1 Chorus Ensemble, the first Boss pedal, was released in 1976 by Roland's new Boss division, and Boss products today are sold under the Roland-owned boss.info site. Boss also builds on Roland designs, such as the BP-1W preamp circuitry derived from Boss and Roland effects.
What was the first Boss pedal?
The CE-1 Chorus Ensemble, launched in 1976, was both the world's first chorus effect pedal and the very first Boss pedal. The compact pedal line followed in 1977, debuting with the OD-1 Overdrive, which had only Level and Overdrive controls.
Is the Boss OD-1 still made?
No. Boss discontinued the OD-1 OverDrive in July 1985. Its sound carried on through the SD-1 Super OverDrive, released in 1981 with a tone control added, and Boss has revisited the design in later pedals such as the OD-1X.
What is the difference between the Boss SD-1 and the SD-1W Waza Craft?
The SD-1 Super OverDrive arrived in 1981 as a descendant of the 1977 OD-1, with a tone control added. The SD-1W, released in 2014, is a Waza Craft edition of the same pedal with a mode switch for extended range, offering Standard and Custom modes in a premium analog build.
What does Waza Craft mean on Boss pedals?
Waza is the Japanese term for art and technique. Waza Craft pedals are special editions that Boss describes as the pinnacle of its design and craftsmanship, and every Waza Craft pedal features a mode switch for extended range. Examples include the DM-2W, SD-1W, HM-2W and FZ-1W.
What is Boss MDP technology?
MDP stands for Multi-Dimensional Processing, a proprietary Boss technology that analyzes the elements of your sound in real time, including frequency, overtones, dynamics, pickup response, note register, single notes versus chords, bends and vibrato, then processes each element uniquely. It appears in pedals like the DS-1X, OD-1X, BB-1X and CP-1X.
Is the Boss VB-2 vibrato discontinued?
The original VB-2 Vibrato is no longer in the standard line, but Boss revived it in the VB-2W, a Waza Craft vibrato pedal. The VB-2's special Unlatch mode, which adds the effect only while you hold the switch, is part of what made the original sought after.
