SKU: SY-1000

Product Description

The SY-1000 is a culmination of Boss and parent company Roland's world-leading innovation, incredible array of editable sounds and seamless workflow designed specifically for guitarists. Who could you possibly trust more to adapt synth technology for the trusty old guitar than the guys who started it all?

Without a doubt, the SY-1000 packs the deepest and most satisfying selection of tones ever crammed into a synth pedal. Modelling capabilities have been refreshed and refined, providing a brand new experience for players who are familiar with the selection of legacy Boss and Roland sounds. 

Choose from analogue synth leads, warm pads, ambient textures, modelled electric and acoustic tones and more individually or three at a time. You can even apply alternate tunings no matter your guitar's current setup. Pitch, level, layering and panning options are available for each instrument, on top of specific controls applied to effects. Even better still are two distinct modes for both bass and electric guitar, which adapts sounds appropriately to each instrument.


Step sequencers are rarely heard or seen applied to guitars, but the SY-1000 unlocks that potential. In this case, its two individual sequencers allowing fully customisable steps across pitch, filter and amplitude options, as well as the ability to stack your three synth sounds for fully fleshed-out repeatable melodies. Stranger Things intro? No problem.


Other synth pedals struggle with tracking once you've applied all your weird and wonderful sounds. But the SY-1000 is powered by the latest custom DSP and 48 kHz/32-bit processing, killing any latency between your playing and what you hear. To put this into perspective, the SY-1000 has six times the power of the lauded SY-300. 


Dialling in sounds is easier than ever. The SY-1000 borrows both controls and modelling sounds from Boss' flagship GT-1000 multi-effects unit, praised highly for its simple operation. Shape your tone quickly and efficiently using hands-on controls, an LCD screen and sensible editing interface. Go beyond the SY-1000 and create your sounds using the Boss Tone Editor Studio software for in-depth tinkering.

Dr Steve Harris16th Mar 2020

The Boss SY1000 is the revolutionary guitar synthesiser I've been waiting patiently for since buying a GR700 from new in the 80s. With the SY1K, Roland have taken Harmonic Restructured Modelling - where they mangle the time/frequency of the sound of a guitar string to make it sound like other things - to a whole new level where the raw building blocks of an analogue synthesiser are rendered indistinguishable from any decent virtual analogue synthesiser you might load onto your computer. I've programmed convincing emulations of Moog, Oberheim, classic string synthesisers and (other, older) Roland synthesisers in my first week with the unit, and can play them all without tracking delay. Add to that more than enough GT1000 class amp and pedal modelling to get you through most gigs, and the much improved emulations of acoustic (and electric) guitars and you have an unbeatable package.
