BOSS RBF-10 Flanger,'80s
RBF-1 Flanger - Part of the classic Boss Micro-rack series
which graced a huge amount of home studio's back in the 1980's.
back in the days just before fostex brought us cheap multitrack reel to reels, portastudios or 1/2 inch 8 tracks ruled the budget home studio world.
Of the common, cheap, but decent fx available at that time, we already had Rebis, who's 'rack & card' based FX system had become a common sight in many budget studios as had the similar Stdiomaster rack-range... Then there was a brand called Accessit with a cheap range of fx/proccessors too... and there were kits if you were a sparky person.
Boss decided to get in on the act, which made sense as they are the budget division of Roland corporation, who were already turning out a decent range of fx & processors of their own.
The Boss Micro range quickly became a firm favourite in the UK as a range of cheap but decent quality units perfect in both price and SIZE for the home studio enthusiast & smaller commercial studios.
Units could be bought individualy, and a 'master rack' could be purchased to house and power a whole set.
Individual units took a wall wart supply for their DC power, the optional 'rack' could have a distribution power unit to power the whole lot (RPW-7 Power unit).
I think you could also get an optionable pressed steel 19" rack bay to house 2 Units at a time in a convetional 19" studio rack.
The Mini-rack itself was a small plastic unit which had dinky but pointless 'grab-handles' moulded into the front sides. ... still.... it looked nice, the units worked well for their price, and lets face it, for the quickly expanding budget studio field they were perfect, and if you had a whole range the mini-rack had a small footprint being half-rack size so it could be easily placed on desktops etc & took up little room in what for many was bedroom studio use.
