Boss SE-50 Stereo Effects Processor in very good+ condition with some very light
wear from normal use. Works and sounds great. Includes manual on CD and power
supply.
The SE-50 is a multi effects unit. It was released 1990 and was in production
until the SE-70 was released 1993. The unit is equippped
with a 16 bit DA/AD converter and uses a sampling frequency of 32kHz or 48kHz
depending upon the chosen effect. The SE-50 has both stereo in and out, is fully
MIDI compatible and its 100 user presets can be stored externally using the MIDI
interface.
The SE-50 has 28 built-in algorithms. An algorithm is a predefined
combination of effects. Several of the 28 algorithms are single effect
algorithms so thought it may sound like the SE-50 can combine effects in many
ways, this isn't absolutely true. Guitar players may be interested to know that
the only algorithm capable of producing distortion is Guitar Multi and the only
settings for the overdrive/distortion is level/drive and turbo on/off. The unit
is very much focused on reverb
where 9 of the 28 algorithms are reverb
only algorithms.
There are 128 presets. Preset 101-128 cannot be overwritten as they
demonstrate each of the 28 algorithms. Preset 1-100 are user programmable and by
copying one of the 28 fixed presets into one of these locations a start position
with the chosen algorithm is easily achieved.
The 28 algorithms:
1

Hall 2
Hall reverberation with mid boost

A slightly pitch shifted signal is added to the original
signal
12
Multi Pitch Shifter

Requires a microphone to R input and keyboard to L input. Has a
chorus and noise supressor
connected in series from the vocoder's
output.
