Best Budget Synthesizers Under $250The world of plugins and software certainly has its advantages: price, convenience, and the fact you won’t need to free up any space on the desk. But sooner or later, most musicians get hungry for something hands-on.
Many sought-after synths reach well into four-figure price tags, but getting started with hardware instruments is remarkably affordable if you know where to look. Today, a vast number of synthesizers are available for less than $250, suiting all manner of workflows and styles.
One final note beforehand: if you’re willing to up your spend by around $50, you can get your hands on popular instruments like the Korg Monologue and Arturia Microfreak, as well as the Moog Mavis DIY kit and Sonicware’s roster of genre-specific Liven grooveboxes.
But if you’re on a strict budget, here are the best synths costing less than $250 and why they might be right for you:

Behringer Mini range: The cheapest hardware synths available
Korg Volca series: The best budget synth ecosystem
Teenage Engineering Pocket Operators: Affordable portable sequencer synths
Stylophone Gen X-2: A quirky monophonic synthesizer under $80
Blipblox After Dark: Explore synthesis for the first time
Behringer TD-3: The cheapest 303-style synth
Cre8audio East Beast and West Pest: An affordable entry to modular
Korg NTS-1 Digital mkII: Expandable DIY synth with custom wavetables and effects
Bastl Kastle range: Most affordable experimental synthesizers

Behringer Mini range: The cheapest hardware synths available

Price: $99 – $129 at Sweetwater
Love him or loathe him, Uli Behringer dominates the budget synth market – so much so, we could probably dedicate this entire list to his company’s products, many of which reinterpret existing instruments.
If you’re looking for maximum bang for your buck, the Behringer Mini range is a good place to start. These compact synths condense recognisable pieces of vintage gear into an ultra-portable format with a two-octave touch-sensitive keyboard.
Whether it’s the Minimoog Model D’s three-oscillator architecture, the phase distortion synthesis of the Casio CZ-1, Oberheim-style pads and brass, or the joystick-controlled vector synthesis of the Prophet VS, Behringer’s Mini range provides an inexpensive introduction to a variety of classic sounds.
Korg Volca series: The best budget synth ecosystem

Price: $129 – $179 at Sweetwater
When Korg launched the Volca line in 2013, few could have foreseen how enduring the format would become. These battery-powered units typically pack a built-in speaker, touch keyboard, MIDI input, sync connections, and a sequencer into a chassis around the size of a book.
The original Beats, Bass, and Keys models covered the basics required for simple hardware jams, but Korg has since used the format to explore more specialised instruments, including the acid-inspired Volca NuBass, the West Coast-influenced Volca Modular, and the six-operator Volca FM2.
Across the wider line, Korg has covered analogue and digital synthesis, sampling and percussion, and even the Volca Mix for connecting several instruments, making the range an excellent starting point for a tabletop performance rig.
Teenage Engineering Pocket Operators: Affordable portable sequencer synths

Price: $59 – $99 at Teenage Engineering
While Teenage Engineering holds somewhat of a reputation for premium price tags, the Pocket Operator series proves the Swedish company is capable of producing genuinely inexpensive instruments too.
These sequencer-based synths, drum machines, and samplers are smaller than a smartphone, with exposed circuit boards and animated LCD screens that look like some kind of musical calculator. Each one is centred around a grid of buttons, two parameter knobs, and a 16-step sequencer with parameter locking and punch-in effects. There’s also a built-in speaker for annoying fellow passengers on your commute.
Our recommendation? The PO-32 is a surprisingly capable drum synth that can import sounds created using Sonic Charge’s microTonic plugin. The PO-33, meanwhile, is a compact sampler and spiritual predecessor to the larger EP-133 K.O. II.
Stylophone Gen X-2: A quirky monophonic synthesizer under $80

Price: $77 at Thomann
Invented in 1967, the original Stylophone was closer to a toy than a fully fledged synthesizer, though it still managed to make an appearance on recordings by the likes of David Bowie, John Lennon, and Kraftwerk.
The lineup has expanded since the product’s 2007 relaunch, with the Gen X-2 standing as the most capable Stylophone yet. It retains the iconic stylus-operated keyboard, but adds considerably more control over the sound, including an attack/decay envelope, a resonant filter, pulse-width control, and an LFO.
Although the resulting instrument remains deliberately simple, its distinctive, buzzy character gives it an identity of its own – and one that can communicate with a wider setup than its appearance might suggest, thanks to CV and trigger connections.
Playtime Engineering Blipblox SK2: Explore synthesis for the first time

Price: $219 at Sweetwater
Falling somewhere between Hasbro’s Bop It and a spaceship cockpit is Blipblox, an instrument developed as an approachable, child-friendly way to explore synthesis and sound design.
Don’t let its eccentric appearance fool you – it offers considerable sonic scope thanks to 16 oscillators, a multimode resonant filter, two envelope generators, two LFOs, and flexible modulation routing. More than 300 onboard melodies can be used to play your patch, as well as external MIDI input, and there’s a built-in drum machine and delay too.
Rather than creating specific patches, the Blipblox is designed for playful exploration – but if the colourful SK2 is a little too toy-like, Playtime Engineering also makes a blacked-out After Dark version.
Behringer TD-3: The cheapest 303-style synth

Price: $149 at Sweetwater, or $199 for the Modded Out version
With original TB-303s costing several thousand dollars and Roland’s Boutique TB-03 version sitting around $400, Behringer is the best bet for hardware acid basslines on a budget.
The TD-3 closely follows the original architecture, combining sawtooth and square oscillators with a resonant four-pole low-pass filter for convincingly squelchy timbres. However, Behringer has replaced the notoriously quirky sequencer with its own programming workflow, and added a Boss-inspired distortion along with modern connectivity.
For a wider pallette, Behringer also makes the TD-3-MO, which adds modifications inspired by decades of customised 303s including a sub-oscillator, adjustable slide time, a ‘Muffler’ filter control, and expanded patching.
Cre8audio East Beast and West Pest: An affordable entry to modular synthesis

Price: $249 each (East Beast and West Pest) at Sweetwater
Using ‘modular synthesis’ and ‘affordable’ in the same sentence often feels difficult to justify. Although many modules are relatively inexpensive individually, assembling even a basic playable system can quickly add up. Cre8audio offers two more affordable entry points inspired by contrasting synthesis paradigms.
The East Beast adopts the subtractive approach favoured by Bob Moog, using enveloped filters to shape harmonically rich waveforms like saws and squares for more traditional sounds. The West Pest, on the other hand, is inspired by the additive techniques pioneered by Don Buchla, using wavefolders to add harmonics to simple sine waves, and it’s geared more towards discovering unusual and unexpected sounds.
Both units are semi-modular, meaning they can be played without inserting a single cable – but once you’re ready, the 4×5 patchbays provide hours of exploration, as well as easy integration with a larger system when the modular addiction inevitably takes hold.
Korg NTS-1 Digital mkII: Expandable DIY synth with custom wavetables and effects

Price: $169 at Sweetwater
Korg kicked off its build-it-yourself Nu:Tekt line with the original NTS-1, a compact digital synthesizer kit that paired a programmable oscillator with a useful collection of built-in reverb, delay, and modulation effects.
The mkII version introduces an improved synth engine, an expanded 18-note multitouch keyboard, an 8-step sequencer, and advanced MIDI capabilities – though the original model remains worth considering if you’ve got less to spend.
What truly sets the NTS-1 apart from most other budget synths is its expandability. It supports Korg’s Logue SDK, allowing users to load custom wavetables and effects onto the instrument via the Librarian app. Thanks to a stereo input, these effects can be used to process external audio – so the NTS-1 will remain useful even after you acquire a more powerful synthesizer.
Bastl Kastle 2 range: Most affordable experimental synthesizers

Price: $194 each at Perfect Circuit
Bastl’s original Arduino-powered Kastle offered an intriguing, hackable approach to semi-modular synthesis. Its successors run on more powerful Raspberry Pi processors, but retain the pocket-sized format, nifty jumper-wire patching sockets, and a heavy dose of the weirdness that made the original so appealing in the first place.
The Kastle 2 Alchemist is the most conventional of the trio, albeit only by Bastl standards. Its monophonic four-oscillator ‘hybrid synthesis’ engine combines five morphable modes — Filter, FM, Supersaw, Hypersine, and Glitchnoise — with a customisable, patchable sequencer.
For experimental sampling, the Kastle 2 Wave Bard can turn user-loaded sounds into unpredictable rhythms, textures, and riffs. FX Wizard completes the set by processing external audio through an assortment of delay, modulation, and pitch-shifting effects that range from subtle and refined to unwieldy sonic transformation.
