Boss Micro Studio Series Effects

The year was 1985, when Boss released a range of compact half rack effects units for the home recording musician. They may not have been perfect, but they provided many of us on lower budgets access to some great studio tools!

Boss‘ Micro Studio Series packs the superb performance and numerous functions found on large effects racks into compact one-half rack-sized units. These units make fully professional specifications and capabilities available at affordable prices for all applications, from stage and studio to home recording and amateur enthusiast purposes. For high performance, you need the new standard in effects – the Boss Micro Studio Series.

Compact design means high performance in these half rack-size units
The Boss Micro Studio Series is exactly one half the size of a conventional rack-mounted unit, with dimensions of only 218mm(W) x 44mm(H) x 160mm(D), but there are no compromises in performance or functions. In fact, the Boss Micro Studio Series provides the superior specifications and excellent functions that can only be found in costly larger units.

2 Boss Micro Studio Series units fit in one 19″ EIA-Standard rack shelf
Compact enough so that two units can fit on a single 19″ rack with the optional RAD-10 rack-mounting adapter. These half-size units can double the effects capability of a single rack shelf or cut by half the space and weight required by a single effect. The compact dimensions of the Boss Micro Studio Series also make it easier to use them on stage or in studios, and take up less space in your setups.
