Hi Selling my Boss SE50 it’s a super little half rack unit with some good sounds / algorithms
It’s simple to use but you can also dive in and tweak it to your desired sound . It’s got a good detune setting courtesy of the pitch shift effect I think you can stack about 5 and detune about 10 cents
I kinda dig that Landau sound . It’s a very fun unit especially with the various reverb delay chorus fx & algorithms. It’s not limited to guitar it’s also suited for keyboards vocals and mixers etc .

a super retro little unit made in 1990 doesn’t take much room up either
from a smoke & pet free home . I’ve already got it packed up absolutely securely . It’s in a box with bubble wrap and cardboard sandwiches and extra cardboard around the walls etc plus more bubble wrap . I tested it all out and it’s working great and is so much fun . £99.00 posted

It includes The Original Manual a PSU & a couple of patch leads
thanks so much for looking

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 1	Natural hall reverberation
2	Hall 2	Hall reverberation with mid boost
3	Room	Room reverberation
4	Plate	Simulation of a metal plate vibrating to produce reverb
5	Ambience	Ambience microphone reverb
6	Gate Reverb	The reverb is muted partway through
7	Stereo Reverb	Two channel reverb with common settings for both channels
8	Multi Delay	5 delays in a row
9	Multi Tap Delay	5 delays in a row with different settings than Multi Delay
10	Stereo Delay	Delay with independent settings for each channel
11	Space Chorus	A slightly pitch shifted signal is added to the original signal
12	Multi Pitch Shifter	4 parallel pitch shifters adjustable to +/- 2 octaves
13	Stereo Pitch Shifter	Independant pitch shifting on each channel adjustable to +/- 1 octave
14	Stereo Flanger	A flanger and gate effect connected in series
15	Stereo Phaser	A phase shifted signal is added to the original signal
16	Vocoder	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.
17	Rotary	Simulates a rotary Speaker. Has a noise supressor in series with the rotary’s output
18	Keyboard Multi 1	A stereo series consisting of: Equalizer – Delay – Chorus – Reverb
19	Keyboard Multi 2	A stereo series made up of: Phaser – Equalizer – Chorus – Reverb
20	Rhodes	Simulates Fender Rhodes electric piano sound using a stereo series of: Equalizer – Phaser – Noise Suppressor – Chorus – Panning – Reverb
21	Guitar Multi	A stereo series consisting of: Compressor – Overdrive/Distortion – Equalizer – Noise Suppressor – Delay – Chorus – Reverb – Line Driver
22	Vocal Multi	A stereo series made up of: Limiter – Enhancer – Noise Suppressor – Delay – Chorus – Reverb
23	Stereo Enhancer	A stereo series made up of: Limiter – Enhancer – Noise Suppressor – Delay – Chorus – Reverb
24	2 Channel Mixer	This algorithm consists of Equalizer, Noise Suppressor, Delay, Chorus and Reverb. The 2 first effects are applied separately to each channels while the latter 3 can be panned right and left
25	Reverb1 + Reverb2	Separete reverb for each stereo channel
26	Gate Reverb + Reverb	Gate Reverb on left channel, conventional reverb on right
27	Chorus + Reverb	Chorus on left channel, reverb on right
28	Delay + reverb	Delay on left channel, reverb on right

Howdy, Stranger!
