Behringer UO300 Ultra Octaver Guitar Effects Pedal 3-Mode Octave Shifter for Rich Bass Tones with Direct Volume Control

Much better than I expected. I used to have a Boss DS1 and didn't like the sound. This however, used on a low distortion setting and after my Behringer Vintage tube overdrive (which btw is excellent) produces a thick but "pleasantly dirty" sound just right for blues rock. It's dead useful that it has EQ settings too. A good choice.

I'm updating this review to reflect how my opinion has changed over time: this is the best Wah for bass currently being sold, regardless of price. As with most Behringer products this is massively underpriced even with the budget cutting materials. It doesn't feel weak or tacky, I have a Morley too and even though it's basically two slabs of material that you can jump on if you like I don't feel anxious when I switch to the behringer, it's solid. I use many wahs in many wahs. The hellbabe goes so well after my distortion chain, I can either avoid the upper range by using the frequency control or control that fuzz and get some excellent bass stabs that cut through when I need them to. It isn't as fun on its own as my Morley or My George Dennis but as part of a chain this pedal is so versatile and truly works as a true bass wah or as a lead wah for distorted bass that sits high in the mix. As you can see from my photos I have a good frame of reference. Most of my pedals are Boss, EHX or they are amazing pedals from companies that are famous in other areas, like Fender or Marshall. Behringer pedals hold their own, this and the tube modeller are overpowered for their price, and the sansamp copy isn't awful either.

Good value, and greta wah sound. Easy to switch between wah and no wah wah. One small thing, you need to disconnect the battery if you don't want to drain it instantly when not in use

This pedal is amsolutely fantastic for the price. Pure HM2 grind! Everything dimed but dial the mid knob back ever so slightly to get that original Boss HM2 tone. Shame its plastic.

Sadly I got the high pitched whining noise as soon as I plugged it in, tried different amps, guitars and cables just in case but same problem

Very good for price performance it's affordable and I can literally get any tone I wanted with this. İt has a very good sound quality it doesn't have delay the brightness is adjustable and the tone accuracy is very good also with my marshall amp I can't get the tones I wanted now I can with this one

Fairly well documented now that this is more or less identical to the pedal it's based on which is many times the price. If you want to try vibrato on a budget it really is the only pedal for the job. Covers everything from a subtle movement to underwater sci fi noise weirdness.

Great piece of kit, works very well, unfortunately getting it to do what you want takes some time, especially as it does not come with anything resembling a manual, but once you've got there it's perfect. Programming it is frankly a pain in the neck, even with a PC editor. I do, however reccomend downloading a free PC Editor, because otherwise, as far as I can tell, buttons 1-5 can only be programmed as programme change (PC) functions, buttons 6 and 7 can only be control change (CC) functions and 10 can only be notes. As I wanted only CC functions I had to use a PC Editor to programme it, one bank at a time, which took a while, but I'm now very happy with my setup. Pros: -Versatile - with around 100 buttons (10 buttons x 10 banks), plus expression pedals, and being able to programme (with an editor), PCs, CCs and notes, this thing can do a hell of a lot -Sturdy - built very well -Functional - it works Cons: -Programming is tedious, especially if you're not familiar with MIDI controls -Hefty - takes up a fair bit of space and isn't exactly lightweight either. I haven't had to move it around town yet, but I don't expect that'll be trivial - No manual, which is just laziness on the part of the manufacturer It's a good piece of hardware and I can't really fault it, but, to a non-engineer, it looks as though it wouldn't have been too difficult to make it better, e.g. by letting you select whether you wanted PC or CC control for any given button or simply providing some instruction on how to programme it

Da un overdrive/distorsión muy interesante generada por un auténtico bulbo 12AX7. Puedes obtener un sonido desde rock clásico (varios niveles de OD) hasta distorsión de heavy metal de inicios de los 80 (suena más a Motley Crue que a Metallica, por decirlo de alguna manera). Tiene además de un EQ de tres bandas, una puerta de ruido (noise gate) que resulta muy útil cuando aumentas mucho el nivel de ganancia, aunque en general no es ruidoso. Es el doble de voluminoso que un pedal tipo Boss (para tomar en cuenta) y viene con su propio adaptador incluido. Llegó rápido, en perfecto estado y está sólidamente construido. Sí lo recomiendo muchísimo si buscas versatilidad de distorsiones y OD clásicos en un solo pedal.

Used on 2 tours. Had no issues and kept me in tune.

The pedal is solid. The EQ is very versatile and the gain can go from sweet overdrive to big distortion. The only con is the pedal size, it takes a lot of space on pedal boards.

BOSSのオーバードライブとVOXのアンプの併用で歪ませていましたが、今後、ライブやスタジオで違うアンプでVOXの歪みが再現できなかったら？と最近考えていました。 そして先日ベリンガーさんのヴィンテージディレイがとても音が良くしかも安かったので、ベリンガーでドライブ系を探してみたら、この商品が目に止まり値段も3300円しないので迷わずポチり。 結果、とても良い買い物が出来ました。 VOX＋BOSSのSD1の時よりウォームで正にヴィンテージ感が満載のドライブ音。大満足です。 ノイズもBOSSのSD1やVOXのアンプの歪みと比べて気になるものではありませんでした。 歪ませた時のノイズはある程度受け入れてるんでノイズをカットするエフェクターを今後購入予定です。その時も是非Amazonさんとベリンガーさんのお世話になりたいと思っています。本当に良い物作りをしてるメーカーだと思います。 本体は強化プラで金属ではありませんが耐久性に不安は感じない作りです。 これからも良いエフェクター作りを期待しています。楽しみです。

Although not the best choice for bass, this does a great job for replicating bass tones for 90s bands like silverchair, nirvana and Alice in chains. The bassline of Israel’s son using this pedal is flawless.
