Product Description

Every once in a while an effect shows up ahead of its own time and before guitarist figure out what do with it, it’s gone out of production. Sometimes this results in effects that, in spite of their retail price, become extremely valuable because of the rarity of the effect. The only way to get your hands on these kinds of effects is to buy them used in varying conditions with no warranty and at sky high prices.

If you’re the kind of guitarist who actually has that amount of money to spend you can buy the pedal. But then what? Take it gigging on the road? On tour? Or just leave in a vault somewhere and never really use it?

Crescendo Auto Swell brings an iconic and rare effect and makes it readily available and built to withstand a lifetime of abuse.


  • Lets you create rolling and powerful volume swells
  • Instantly accessible 2-knob interface featuring sensitivity and attack
  • Controls attack time to create almost violin-like guitar lines
  • True bypass for ultimate signal integrity
  • “Built-like-a-tank” metal chassis
  • Runs on 9 V battery or the PSU-SB DC power supply (not included)
  • Designed and engineered in Denmark

Mr Graham Ritchie10th Nov 2023

Very simple pedal, so not a great deal to comment on, threshold setting initially takes a little bit of familiarisation, but that's true of any effect. Attack time is OK. For the price, this does what it says on the box. Build quality and finish is excellent.

Great pedal - gives a great consistent approach when lots of volume-swells are required.

Mr Jim Scadding12th May 2021

Great sounding effect and great price...but heavy, bulky and battery placement inconvenient. However still recommended for the quality/price.

Faithful clone of the rare Boss-SG1 (Slow Gear), at a fraction of the price of a second-hand original. Responsive controls, built like a tank!

Wesley Nel11th Feb 2021

A very unique pedal that may not suit every style not playing..it's like a delay mixed with a synth kinda effect. You can change the sensitivity of the effects too but great to give a song bit more body.

Great value easy to use Auto Swell pedal. Perfect for ambient guitar and excellent value. Built like a tank but paint design looks a bit ugly!
