Effect unit: Boss SE-70
Review by: Mike Perkowitz (map@cs.washington.edu)

Summary: Half-rack stereo analogue/digital multi-effects unit

Years Made: still being made
Inputs: stereo input, pedal/switch
Outputs: stereo output
MIDI: in/out
    MIDI controllers (aftertouch, CC, etc): 
	can accept four controllers per program assigned to fx parameters
    Sysex patch dumping: yes (?)
    Sysex parameter control: no (?)
Other external control: pedal/switch inputs
Patch storage: about 150 patch locations, 100 programmable
Available effect(s):
	phaser, chorus, distortion, amp simulation, vocoder, EQ,
	  pitch shift, reverb, delay, and many others
	Each program is based on a particular basic routing (these are fixed;
	  there are about 50 different ones). Each effect in that routing
	  can be on or off, and has several parameters that can be set. not
	  all of these parameters can be controlled via MIDI.
	Some of the effects (e.g. distortion) are actually analogue
Interface: buttons, data wheel, decent display, all in a half rack space
Routing: many stereo effects, many routings with mono input but stereo output, 
	no way to place separate effects programs on the left and right 
	channels (except for one or two routings that are set up this way)
Tabletop/rack: half rackspace unit
Known problems:
Accessories:
Related gear: 
	SE-50: similar model, without the analogue effects (?)
Price range: selling new for $600-$700 (in mid 1995)
Availability: widely available new, somewhat rare used
Comments:
    Strengths: good sounding effects, lots of possibilities, some midi
	control
    Weaknesses: some of the effects are noisy
    Overall: amazing amounts of power in a tiny package
