I need to kick off this review by saying that I haven't got (or had) any other tremolo pedals to compare this one too but. . . TLDR; I don't use Tremolo all the time, but when I do, I'll be using this one :).If you don't know what a tremolo pedal does, you may want to read up on that, but in summary, it makes your guitar go louder and quieter, and you can control the variation in volume, and how fast it varies.First things first, as you'll see from my photo, my pedal is a rather dashing shade of canary yellow, as opposed to green. I preferred it, but ymmv.ControlsThe depth knob controls how big the variations in volume should beThe bias knob controls how much of the time it should be louder vs quieterThe speed knob controls how fast it changes volumeProsLike other micro pedals I've had, it's a solid metal enclosureTrue bypass footswitchPaint quality feels great, and barring accidents etc, I'm sure it will keep looking goodThe range of the effect you can get is really wide - from a nice subtle (which is what I've got dialled in here) pulsing, to racing fast.It draws minimal current (26mA).It doesn't add any noise to my signal chain.ConsThe only downside to this pedal I could find which is common to all micro pedals, is that it can't be powered by a battery - but this isn't an issue for me.Overall, this pedal has continued to vindicate my buying of cheaper pedals and I'll definitely be buying more.

Great little pedal , easy to transport if pushed for space and cannot carry a full sized pedal board.

This Bluesy OD is fantastic and incredibly cheap. On its own you can dial some nice bluesy crunch. Gain stacked in conjunction with my Behringer TO800 I can get some incredible gain even at low volume. The selector switch toggles between Fat and Normal, the change is very subtle but could prove useful. The unit doesn’t generate any noticeable hiss or noise that I can detect. The only downside is that the volume and tone controls are very small.

Ideal for my pedal board takes up very little space and works well. No noticeable signal degradation or distortion. Easy to use and very functional

This pedal looks pretty and is very sturdy but it does not behave like a compressor. You will need a 9v power supply (not supplied) to make this pedal do anything. The one I received added distortion or an overdriven sound and some sustain. When I played either an acoustic and a clean electric guitar through it the sound was driven and distorted and the volume increased. On my pedal the LED didn't work so even if it had produced a compression effect it was faulty. Some people might like the effect but it didn't work for me. Another thing I noticed is that the reviews seem to refer to different pedals (tuners, flangers etc.). Caveat Emptor.

Really liked the small size and solid build. The ability to add or take away from the signal is an real plus and being able to boost my bass signal was impressive through the pa!

Nice little chorus. Good for price.

I was looking for a pedal to increase volume for short bursts. Solos etc.I thought an eq pedal might be the way to go but thought I'd try this for £22 at time of purchase. Really glad I did as it's surprisingly versatile. It can work as a clean volume boost, a bit of extra gain and no extra volume or any combination. The 2 band eq is pretty handy and can give lots of extra treble to cut through.For home use I've got it in front of an no master volume, no fx-loop valve amp and you really can add extra bite to the pre-amp without wasting your overdrive pedal.The small size means it flops around a bit when you step on it if you don't nail it down but thats the same with all these micro pedals.Great bit of kit for the money. Wish these cheap brands had been around when I was starting!
