cool
dope sounding as hell and extremely cheap, can be used for weird noises like wailing and machinery
Preferred Settings + Usage:
the LFO, delay and shitty "keyboard" can be used to make dope sounds like screams

Noisy and cannot handle amplified aux. input
I only use this as an effects unit for my Casio CTK-495. The Monotron Delay does improve the capability of this very basic synthesizer, but you have to turn the Casio's volume down to 2 to avoid distortion, and even then that only works on simple waveforms such as the sawtooth and square (SYN-LEAD 2 and 3). The resulting output from the Monotron (which has to be set to max volume) is very noisy and requires a noise gate.

too simple
the monotron delay is a fun little synth to play with but it doesent have enough features to actually produce music with it

My second synthesizer that I bought in 2015. Another interesting Korg product.
AMAZING! The delay and feedback on this little beauty can evolve the sound accordingly to make a noise-like rhythm. Perfect for any live performance where you need an experimental beat. I would advise using this on a drum machine/drum sequencer to enhance the timbre of the chose beat/rhythm but it is also great it you just want to mess around with it for fun.
Cheap analog fun
Little 1 osc, monophonic synth with an analog filter and SICK BBD. Super useful as a little fx unit, otherwise super useful to annoy your friends. Only thing is that the output is noise as hell.
A novelty toy
While I do like what you can do with it, it's too limited for any serious usage. For it's price, you can get a proper FX rack on the used market that's much better. Wouldn't really recommend it.

Powerful freaky pocket synthesizer.
I have astonished audiences in live performance with this device, holding the little thing up in the air while I turn knobs, making whammy sounds and radio frequencies bouncing all over, echoing, repeating, building, then crashing with down glissandos and micro-periwinkles of dazzling analog pyrotechnics. A big bad noise machine in a small body.

Great effects
only really useful for simple synth effects or using the delay, there's an aux in and a really good analog delay that i use for everything. But for leads and basslines this thing is not really playable. Just a tiny ribbon thing for playing the synth.

Dirt cheap and lots of fun...
Dirt cheap and lots of fun: instant weird and spacey FX...
Begs to be mod'ed as it's could do with some more controls (check the web for mods).
Downside is that it's a bit too noisy to be used all of the time.

The DELAY Analog Ribbon Synthesizer Can be heard throughout many of Jacks songs, whether being used as a synthesizer (Some notable examples being at the start of "Cunk" and very predominantly through Merry Christmas (Uncles in Heaven)) or as a delay in many other songs.
At 4:40 in the video in which Celldweller shows off his studio to Future Music Magazine he says "They look like toys [the Korg Monotrons] and they're actually priced like toys in a way, but so was the TB-303 when it first came out, so don't underestimate the power of this thing, it has a true MS-10[sic], MS-20 filter built in to it".
