SKU: SD-1-4A

Product Description

In 1981, the now-venerable Boss SD-1 pedal redefined overdrive tone. Based around the revolutionary asymmetrical clipping circuit from the OD-1 (one of the 3 original Boss compact stompboxes from 1977), the SD-1 was adored for delivering rich, organic and highly-musical gain while preserving the core sonic characteristics of a player's guitar/amp setup — with a subtle mid-boost to add clarity and punch!

Fast-forward 4 decades, and Boss has celebrated the 40th anniversary of its Super Overdrive pedal with the limited edition SD-1-4A — featuring a reversed colour scheme, gold-capped knobs, a vintage silver thumbscrew and a special 40th anniversary logo box. This is the perfect dirt box for Boss aficionados looking for something with plenty of future collectable prestige.

Key Features

  • 40th Anniversary Livery — Reversed black/yellow finish to commemorate 40 years of SD-1 production.
  • Unique Asymmetrical Clipping Circuit — Produces tube-like overdrive characteristics, transforming any clean-channel amp into a crunchy rhythm machine, or tightening up the tone of a distorted high-gain monster!
  • Dedicated Tone Knob — Wide-range control allows you to go from a warm, singing overdrive to a bright treble-heavy tone that can easily cut through in a mix.
  • Renowned Boss Build Quality — Boss pedals have a reputation for being built like tanks, and the SD-1-4A is no exception. These pedals constantly survive the rigours of rock 'n' roll touring, which is why they're seen at the feet of professionals everywhere!
  • 5-Year warranty — As standard, all Boss compacts receive a five-year manufacturer warranty.

Boss SD-1 - it was that sound I was looking for, that almost everyone is looking for and I bought lots of boutique and expensive pedals and all I needed was this one. Oh well, got one now and it sounds awesome and is on most of the time now.
