Critic Reviews

Roland Boutique TR-09 & TB-03

soundonsound.com

The Roland Boutique TB-03 impresses with its authentic sound and classic design, capturing the essence of the iconic TB-303. It shines with its familiar workflow and ease of programming, making it a joy to use. However, its diminutive size can be a drawback, and the lack of a power supply is an oversight. While not cheap, it offers a faithful reproduction of a legendary machine, making it a worthy choice for those seeking classic Roland bassline magic in a portable package.

Roland TB-03 Bass Line review | MusicRadar

musicradar.com

The Roland Boutique TB-03 captures the essence of the iconic TB-303 with some modern updates, making it a nostalgic yet fresh experience for Acid House enthusiasts. It faithfully reproduces the original's sound and offers an intuitive programming system. However, the lack of a real-time recording mode and the limited updates to the interface and sequencer might feel like missed opportunities. While it sounds excellent, purists seeking true analog might look elsewhere. For most, the TB-03 delivers the classic squelchy tones with additional effects, making it a worthy, compact alternative to pricier vintage models.

Roland Boutique TR-09, TB-03 & VP-03 Review - Return of the Machines

musictech.com

The Roland Boutique TB-03 impresses as a faithful recreation of the iconic TB-303, offering classic acid bass sounds without the exorbitant vintage price tag. Compact yet robust, it includes modern conveniences like USB/MIDI connectivity and onboard effects like overdrive and delay. However, the small controls may be fiddly for some users, and while it captures the essence of the original, purists may notice subtle sonic differences. With its accessible price and authentic sound, the TB-03 is a fantastic option for electronic music enthusiasts seeking that classic 303 vibe without breaking the bank.

Not the same as the original, but for the price...

I owned a TB-303 for many years. I miss the original one, but at the current prices, this is fine.

Pros:

1) USB+MIDI+CV/Gate - Very handy for hybrid (digital/analog) sequencing, especially in ableton with multiple VSTi and external MIDI or CV/Gate devices. In ableton, for instance, you can have layers of VSTI or MIDI instruments playing the same pattern for an orchestral chorus of synths.

2) The 'Tune' knob throws CV pitch changes to keep any receiving synth in-key with it. This was not something the original TB-303 did, nor is something I've ever really seen praised or mentioned, but is really kinda cool.

Cons:

1) No DIN Sync.

2) The sound on this is NOT even close to the original when you get into the higher frequency cutoff and resonance ranges, but you can work-around that.

3) The built-in fx are a joke, let's just be honest. If you don't have anything else at your disposal, then I suppose they're tolerable, but eh.

Very nice, but works diffrently on the distortions than the original

Me and a friend tested all 3 Models (TB-303 original, TB-03, Cyclon TT-303) with 1 pedal distortion. On their own they sound nearly the same, the original had a touch to it that warmthen up things (maybe old electronics drifting) but the TB-03 and the TT-303 sound quite the same. The real diffrence was made when hooked to a distortion!! The TB-303 was shining and pumping and it was spectacular, the other 2 sounded plasticy and hollow. I think the TB-03 and TT-303 as the TB-303 can all shine with the right distortion/delay , but one distortion may not fit everyone. Without FX the diffrence is too little to me to pay X times for such a legend. I'm ok with the boutique remake. Btw, before i got i never touched an original tb-303 so I never had a feel of "the original" which makes the tb-03 as original as it can get.

I've REALLY had to experiment with my bassbot and x0x with my pile of guitar pedals. The modern 303s seem to do best with soemthing with a lot of tone shaping controls whereas I don't remember the original issue 303 I used to borrow being very picky. I definitely do better with my TC Nova Drive then I do with a plain old Rat... really informative review, thanks!

Best 303 emulator

Definitely the best of the 303 emulators. I've used the older TB-3, X0X, and TT-303, but this one features all the features and programming options of the original plus some nice modernization like internal soundcard via usb, delay (tape emulation or digital), and distortion (3 different distortion modes). CV/Gate/Trigger options are awesome for integration into a modular setup. Main drawback is the 1/8" cables are hard to find in a suitable length for a studio set up.

you like it better than the bassbot and x0x? bold... I'm going to have to try one over the weekend

judging by the quality of the 303 VST in Roland Cloud, I wouldn't raise an eyebrow to someone choosing this over true analog options.

A great monophonic synthesizer for live acts...

There's a similarity in sound with the iconic and famous Roland tb303 synthesizer, I think it would be indescribable to define it as a great recreation and a great clone of the original; finally, the effects it has such as distort, reverb and delay are of high quality, I have used them in several productions and I don't regret it...

turn any modular setup into an acid jam

this thing sounds like a 303 that woke up on the wrong side of the bed this morning, crunchy and raw. super fun to program thanks to the 303 style sequencer function and Last and definitely not least, CV GATE OUTPUT, hook this to any modular setup and its like a acid bass video game controller. so much fun

have you used a real 303 or any of the popular clones like the bassbot and x0x? I am flirting with getting one of these but I have a bassbot and x0x so I'm not sure I can justify a 3rd 303 purchase.... thoughts?

if u already have bassbot and x0x i think youre covered. x0x sounds more like the original roland model imo. tb03 is a bit meaner and brittle sounding but not necessarily in a bad way

jimmarchi1

9 years ago about 9 years ago

the x0x sounds great for the most part but the sequencer on the bassbot sounds dead on and that's a lot of the sound to me, the bizarre slide/accent response. but f the bassbot could cover some of that maybe it would be a good thing to have around. i'm sure tis ultra stable being disguised digital technology.

yeah stability is no question. its pretty much a roland plugout vst that just hasnt been set free to the public at least yet. and i agree the sequencer is really where the 303 sound comes from
