Analog Bass Synthesizer and Sequencer, Donner Essential B1 with Intuitive User Interface, 128 Patterns Memory, Saturation & Delay Effects, Make for Classic Acid Sound

You'd be surprised how nice this product is for the price point, but Donner delivers once again. All-in-all, this is a pretty basic bass synth, but it sounds nice through an amplifier, headphones, and speakers, and it's surprisingly premium-feeling for its budget price point. I haven't used all of the features this piece offers yet, but what I have used so far is extremely intuitive and honestly just fun, as a good synth should be. Add into the mix that the build quality is stellar and far above what you'd expect for such an inexpensive analog synth and it also just looks gorgeous that I'd say it's a synth that earns a spot on even a veteran rack with the fantastic experience and versatility it provides. I would certainly recommend.

It's a 303 clone, what else is there to say. The firmware update to add song mode is great, you can chain patterns, so up to 256 steps. The effects are just so-so. The distortion adds a lot of crunch, but the echo is a bit weak, even at full setting it is barely noticeable, it's there, but barely. Nice that it has midi in/out, a headphone stereo out and a mono line out. The sync in and out can be set for various other small instruments, pairs with my korg volcas. One big advantage I see over other clones is the free software, lets you download all the patterns, edit them and load them into the unit. With 128 patterns, you may not need more, but, it is nice to not have to do all the programming via the panel. All this for under $100 when on sale! I was skeptical of the Donnor brand based on other reviews, it's priced perfect to let me play around and I'm not disappointed.

Sounds good. Fun to play. Lots of good preset patterns. The distortion is good. The built in delay not so much. I use an outboard delay pedal and it's much better. As other reviews have noted, it has a high noise floor. But for the money, the Donner 303 is a good purchase. Hard to justify buying the Roland boutique 303 that costs almost $500.

Significantly easier to program than an original 303. Sonically....is it an EXACT match? I don't know, and I don't really care. It's got the right vibe and feel, capable of deep, earth-shaking bass and squelchy fat leads, with sick analog oscillators, filters, and controls. I had a Roland TB-3 prior to this, and there were things about the TB-3 interface that were cool, but it was complicated to program actual basslines and melodies, and the touchscreen interface was better at real-time modulation than composition/performance, for me. I like the Donner interface much better. One downside is there is a faint but audible hiss, instead of dead silence, when this machine is not making music. In a live context it would probably be unnoticeable, but in a studio recording, you would want to gate it or noise-remove it after recording.

I had an original Bass Line. It sounded great, but was difficult to program. In the 1990s, it started shorting out and playing multiple notes when I only wanted one, so I tossed it in the rubbish bin about 10 years ago. This thing sounds exactly as I remember and is much easier to program. It also has distortion and delay, unlike the original.

Excellent product,

Obviously there are bigger and better bass sequencers out there, but they also have bigger price tags. Cant beat this for the price. Solid build and dead easy to use. Good variety of effects and simple to get up and playing. Full manual available on manufacturer's website. Definitely recommend

I returned it. Not because of the sound. It was fine. Not earth shattering but fine. The reason I returned it is bc the buttons on the right - super small font for the labels, printed in black, below the buttons. The contrast of the dark ink on the dark case makes them hard to read. Also, I wanted the labels above the buttons, not below. I kept screwing up and just found the device hard to use bc of its UI.
