JOYO Bass Guitar Pedals Overdrive Amp Simulator Effect Pedal with EQ and Noise Reduction for Bassist Electric Guitar Bass (MONOMYTH R-26)

Love the sound, the build quality and looks. Easy to tweak my sound with it with good clear knobs - worth more than it costs for sure

Use for gigging at end of chain to boost great pedal for price.Solid has fancy lights and give good boost increase.

This is reviewing the Joyo bass compressor.First, the reasons I only give it 4 stars...There is a gain reduction indicator, but it's hard to spot because it's fitted in with the bypass indicators, which I find much too bright, also making it hard to read the knob legends.It needs a good, well filtered 9v power supply, otherwise it can produce a nasty whine.The documentation does not mention the gain reduction indicator, and the on-line reviews I found didn't notice it either. They also don't say what the compression method used is. I can tell you it is the traditional optical, using an LDR (light dependant resistor).I did take mine apart as I was really curious about its workings. Furthermore, I found a very good design and build quality. It is not a simple device. The LEDs are surface mounted and feed clear plastic light guides. The gain reduction LED is a single red in between a pair of green LED's which both light when the pedal is active. Gain reduction therefore shows as yellow! But, as I said, it is a hard to see it happening.The top footswitch operates a chunky PCB mounted button switch and a small relay working from that provides true bypass of the effect. The LDR and its light source are hidden in a lightproof box. There are several opamp IC's marked 2272 which I suspect are TLC2272, a low-noise CMOS type with very nice clipping characteristics. There is an ICL7660 type chip which I suppose is making an extra power voltage from the incoming 9v - this would be the reason for whining noise if a poor power supply is used. I put it back together with no trouble, which is a sign of good engineering design.I'm familiar with many classic effects circuits, but I've no idea if this is a clone of anything or original.It works as expected. Extreme compression ratio can suck out all the attack if that's your thing, otherwise it can do transparent standard peak level reduction as well as anything. It's a shame the gain reduction indicator is so hard to see, that would make setting it up easier.

A great sounding preamp and it looks really good to, especaully the lights. Having the overdrive on a separate footswitch is really handy. I haven't tried the darkglass pedal this is a copy of so can't compare but I'm very happy with this one especially for how cheap these are.

Believe the hype this works great. I was used to virtual studio compressors so when I bought a bass one, the Lax comp by Donner, I wasn't sure what to do and couldn't get a sound I like with just attack release and two volume controls. This having a ratio and tone function, in addition to it not having much of its own sound, unlike the LAX which makes the sounds it makes and not much else as far as I can tell, made it immediately more fun and understandable for me.So far I haven't had it for more than an hour but first impressions are very good.Normal size, massive value.

Absolutely awesome pedal! Darkglass tone for not even half the price.

After having my Stomp fail on me and being quoted a repair bill of nearly what I paid new for it, I've gone with this unit and been thoroughly impressed! Something to bear in mind, the 12 o'clock position isn't 0 so if you have bass set to 12 o'clock for example, this is essentially already boosting bass by 50%

So subtle with all controls turned to noon ie halfway that I thought I’d bought the emperors new clothes! Two things are important to say, firstly different bass guitars will definitely sound different with this gizmo, I tried it eventually with extreme settings on a fender jazz bass and it gave me a slowed percussive sound but on another more expensive active pickup bass there was a very slight effect with the same settings. That may be why different people will experience different outcomes and need different settings.Secondly the release control is a slow release turned fully anti-clockwise, try turning output gain to say 9 o’clock but input gain to fully clockwise ( ie all the input signal gets compressed) then turn all lower knobs fully clockwise except release which should be set fully anti clockwise. By following these settings you should hear the maximum compression this unit is capable of, after that dial back any knob to reduce the effect. It took me quite a while to find out the above and as I said before, up to that time I thought the thing wasn’t doing anything at all much except lower my overall volume quite a bit, to compensate for that I turned up the output gain bearing in mind that any high gain adds more distortion to the signal.Overall I was pleased with the effect of this pedal and somewhat relieved to find it had one! I think overall compression on stage is a bit overrated, for a pub band for example it’s probably unnecessary ( you won’t hear an appreciable difference) and for large venues it’s best left to the mixer out front. However if you want something subtle which seems to clean up the signal from the bass quite nicely then this particular compressor is a reasonable buy at a reasonable price.As an aside it might help if other reviewers mention which bass guitar they’re trying it out on as effects seem to vary a bit.
