A good multi-effects box

By: on 11 February 2024
This effects box is quite well endowed with features - so much so that it can be a bit overwhelming with the choices of effects on offer. Pairs well with a cheap 10W plain practice amp with zero effects - this thing will add everything from compression. drive, amp modelling, modulation, delay, reverb all at the same time. While not the cheapest thing around, you would make up for it as soon as you had to buy 2 or 3 discrete pedals. Granted discrete pedals would be easier to switch certain effects on and off, the portability of this is hard to argue against. Some oddities - the unit can't be powered off when connected to the mains - you literally need to pull the plug! The Acoustic A (acoustic sim) setting is unusable on my unit - creates a strange low frequency buz/hum when playing and doesn't actually pick up the low E and F on string 6. Not sure if this is a feature or fault (have tried on a strat copy as well as an actual acoustic steelstring), but Acoustic B is fine so no complaints.

JOYO Gem Box 2Great unit at a Great Price

By: on 8 July 2023
I was not really sure about this multi effects unit but on receiving it I have used it at 3 gigs now and it is so much better than I expected at this price point. The interface is easy to use and intuitive. Display is easy to read and the effects are really nice. If you are looking for a well priced well featured multi effects unit this is well worth the price.

Great little multi effects unit

By: on 8 June 2020
Bought this to use for busking and I must say I’m not disappointed I did.To be honest the looper length really turned me on to this unit with 3 mins of looping time.But the sounds are pretty good mind you you do have to do some tweaking as not all the sounds are usuable straight out of the box.For the money it’s a good compact little unit.

A little gem!

I’ve only had a few goes with the gembox so far, but I have found it easy to get the hang of and sounds great. I plug it straight into an old Roland Microcube. The drum beat is a fun addition if you listen to a recording of what you want to play, you can tap in the tempo perfectly. Can’t fault it for a smidge over a hundred bucks.
