I wish I had this device to learn knob twisting synthesis with: this is very basic but powerful. It's a great learning tool.The built in speaker sounds horrible compared to the output jack/line out. Through the speaker this was a funny toy that got irritating fast, the output from the line out is making me order another one as a keeper (first one was going to be a gift but I really want to play with it a lot more).I hooked a guitar to the line in and heard nothing. I used an overdrive pedal to get more gain and could hear it coming through but the only knob that seem to have an effect was the cutoff, but that was before I used headphones/amp.I hooked a mono (one black stripe on the connector jack) cord to go from output on this unit to a guitar amp: awesome but loud. There is no volume control but headphone volume on a pair of huge AKG 240 gold dots and a small cheap pair of Panasonics were good (unlike the much pricier Roland which needs the volume set to 10 to be heard-i hook that to speakers and amp).Put the stylus metal point facing right. Slide it in from left going right, remove by sliding it left. I know it's silly: but if you try to take it out like a normal person you may break the retaining clip.Feel: knobs feel cheap but work. Whole unit feels like it weighs less than a single AA battery. Cheap plastic feel: but it's cheap in price and helps you learn synthesis by twisting knobs--not scrolling through boring computer menus. That's also why I like the Roland Gaia, so if you fall in love with the knob twisting simplicity and want more power move up from this to the Gaia (although it costs literally 30 times more, so is apples and oranges past a certain basic point).Check out YouTube for weird mods/circuit bending stuff people are doing with these things. Some people are installing strips on similar instruments that are a foot long and making guitar-like things. All sorts of fun weirdness.Is this musical? Through the speaker: not really. Through line out: very much so. You can select a square or triangular wave and modify them.Set all the knobs to zero except the "cutoff" which you should turn all the way up. This gets you a pure tone. Pitch env, LFO rate and LFO depth are next: play around.Don't just tap, press and hold and sometimes you can get a weird feedback that totally makes random noise after a few seconds.Attack and decay affect the beginning of the signal and the end: so for those tap, then adjust and tap again. Hold and heard the difference at the end that the new decay setting makes. The other knobs are more immediate in results. Some adjustments only affect the start of the sound when you first tap (attack).I swear the vcf button acts like it's pressure sensitive?Sometimes switching between the two different LFO waves makes no difference, sometimes it makes a wild change.You can make tones or complex signals that change and evolve over time (if you press and hold a note).And you probably thought this was just a simple noise maker (:It's also great for cheaply and easily creating beautiful Lissajou Figures on oscilloscopes:http://michaellogusz.blogspot.com/2015/07/making-waves-oscilloscopes-lissajous.html-mike from Detroit ### ⭐⭐⭐⭐ 4.0 out of 5 stars Gakken SX-150 MarkII way cooler than I expected, but for a different reason than expected *by D***N on Reviewed in the United States on October 22, 2015* Got it really quickly after ordering. Well designed and everything works well.Don't much like the ribbon controller.Sounds are good but lack of keyboard sucks,What makes this really cool is the line in feature. Plug in the output of a keyboard to line in and then plug output of SX-150 into an amp. Use the Cutoff and Resonance controls to modify the output and you can make a cheap keyboard sound like a Hammond B3, including key clicks. Experiment with them and use fine adjustments, because a slight adjustment can make a large difference. Fantastic! Also expand tone range and harmonics of keyboard voice. Go from wimpy to AWESOME!!The VCO and LFO sections also can affect the sound of plugged in keyboard. But the push button switches which activate them are momentary switches, not locked on/off, so you have to use a C-Clamp or something to hold the switch down, or replace them with non-momentary switches. That also kind of sucks, but it's pretty easy to work around.All around, it's well worth it to drastically modify and improve signals fed into this thing. Input into line in must be fairly high for it to work, so don't expect to plug a guitar straight into it and expect it to work. You'll probably need a small pre-amplifier for a guitar, or use the headphone or line out from a guitar amp.But the results are amazing and well worth thirty bucks. It's made my keyboards sound so good I've started writing more songs, after a years-long lapse. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Gakken SX-150 MARK II Analog Synthesizer *by D***7 on Reviewed in the United States on April 2, 2015* Pretty cool. Easy to use. LFO Rate is fun to play with. Just received mine. Makes some pretty cool sounds fun to play with reminds me of 1980's arcade games. $20.54 bought mine from e-japan, GREAT seller I highly recommend purchasing from e-japan. Arrived weeks before earliest date (est date was Apr 13-May4 - arrived April 1).Fun to mess around with, Im sure there will be some useful applications for it when tracking with my DAW and also just for having some fun as well.Good stuff. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.dk/products/2111089-sx-150-mark-ii-analog-synthesizer](https://www.desertcart.dk/products/2111089-sx-150-mark-ii-analog-synthesizer) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-05-11*
