## Description

The battery-powered TB-03 is a direct descendant of the famous TB-303 bass line synth. The layout and controls are unchanged, so it works Just like the original. It sounds like it too, thanks to Roland advanced ACB technology that recreates the hypnotic liquid grooves of the magic silver box. But the new TB-03 goes even further, with several enhancements not found on the original model. The four-digit LED display makes programming easier and more accurate, while overdrive and delay effects let you unleash a twisted, tribal wall of sound to send the crowd into a frenzy. Back in the studio, The TB-03 can send control information via MIDI or its USB port, The latter of which also functions as a audio interface.

Review: Cannot go wrong with this one! - I thoroughly studied and compared the audio samples on acidvoice for MONTHS. hours and hours of time carefully listening to one device compared to the other in various states of mind. eventually picked up an avalon for about a grand. I basically agree with the results of these extensive tests, namely 1. 303. 2. avalon. 3. xoxbox. 4 tb-03. except I actually rate the avalon as number 1. that being said, in short- if you have the dollars to throw at this, get the avalon for about $1200- it overall has the best and most features, it is made of metal and weights like 20 pounds, and has far greater capabilities than an original TB-303 by far. i would get that one over an original tb-303, any day- it has far more features (such as the sub/input which is a HUGE thing if you are Aphex Twin influenced) and is better built. Do NOT for any reason purchase an original TB-303! the avalon actually sounds better and is better in every way (even over devilfish modded 303s). now for 1/8th to 1/10th the cost of the resale on an original tb-303 (and 1/3rd the cost of the avalon), you can get this delightful little gem which does everything the original does + more! it sounds near identical and for the most part indistinguishable without distortion applied and even with, it still sounds really amazing and only a carefully trained ear could tell the difference! i love that it is battery operated (or powered by 500mA micro-USB) and has its own speaker, which means i can pack in in my school back pack and program insane loops between classes. absolutely ZERO regrets on this purchase! the only other i would recommend as a possibility is the behringer TD-3-SR, which is less than half the price of this unit. if i get another 303 clone that will be my next purchase- but overall this one is better, for starters it has a digital display showinging the BPM (unlike the behringer OR the avalon in fact) which is incredibly helpful. i totally love the digital display screen on the TB-03! ie i would get this one before the behringer unit. yes, there are a few minor differences soundwise, and idk wtf with the 1/8" output plugs, but hey, adapters work! the built-in distortion (3 types available) means you do not have to pick up a RAT pedal, and the built-in delay means you do not have to pick up a delay processor as well. delay is really important, especially if you are making trance of any sort. overall: entirely cool! I TOTALLY LOVE THIS THING!
Review: Buy It! But Only If You're A Fan Of The TB-303 Sound. - There's something special about turning a real knob on a hardware synth and getting a true, faithful recreation of the TB-303 sound we know and love so much. The knobs being so small though, make it better for the studio where you can afford to make more mistakes for re-dos or use automation in a DAW. Overall, impressed with the build quality and most of all...the squelch sound. Fun to learn programming it as if I was doing it back in the 80s/90s on the real thing. Great buy, better than any VST emulator by far.

### ⭐⭐⭐⭐⭐ Everybody needs a 303
*by J***. on January 10, 2020*

I know that the Behringer clone is coming out, and I ordered one, but this thing sounds amazing, and looks better than the Behringer ever could. I had a TB3, and I hated the thing - these TB-03 units look and sound like the real thing. We'll see how much of a difference real analog makes with the Behringer, but the TB-03 is a home-run. ACB technology sounds amazing (I also have a System-1, System-8, and SH-01), as well as a Jupiter-Xm that uses ZEN Core. I have Phoscyon, ABL3, and some other software clones, and this sounds so much better (along with the Roland Cloud 303). Complaints: okay - I get it that the accent isn't perfect, but if you need pristine 303, it's time to pony up the cash, or get over it
