Studio Effects Processor

The Boss SX-700 is a 1-U rack multi-effect processor, capable of professional-grade effects.  If you like Boss' series of pedals, and Roland's RSS surround technology, you are going to like this product.

The "effectors" can be assigned to various algorithms, allowing the user to patch effects in any order - this module is definitely a tweaker's toy.

There's a harmonizer on-board, capable of adding up to four-part harmony to the incoming signal.

RSS (Roland Sound Space) is an effect taken from earlier Roland processors, that creates stereophonic sonic images in three-dimensional spaces.  It truly is a unique and great-sounding effect.


The SX-700 sounds good.  High quality effects in a compact 1-unit rack mount.

There is a fairly large backlit display, and dedicated EQ, MOD, DELAY, REVERB and RSS buttons, that you can easily turn on and off.  Full MIDI specification (in, out, thru) make this module easy to integrate in any setup.


BOSS SX-700 audio demos

Here below are some of the SX-700's factory presets.

I used a Generalmusic Equinox 61 with its internal effects turned off for the examples.  The signal is first heard dry, then thru the SX-700 at 50% fx.
