Spur GemBox Multi-Effects Pedal with Built-in Drum Machine

Overall, for the money, this device is quite impressive. The build quality is good, it appears to be robust and well designed. Sound quality is excellent, display is clear. The instruction manual is pretty bad, though. Shows signs of being poorly translated. It's taken me some time to get to grips with the device's potential, as, for probably good reasons, all the available functions are there but hard to get at because there simply aren't enough buttons. Two rotating knobs, two foot switches and the wah pedal are not enough to allow easy access to everything. The built in effects are okay and compare well with those in my Fender Mustang I amp. It's a little challenging to make your own, but maybe that's just me. Built in drum machine is excellent but maybe the range of beats could be wider. It could do with an on/off switch. A pretty good buy.

Spur GemBox Multi-Effects Pedal with Built-in Drum Machine

This is a brilliant piece of equipment. Does away with the need for a backing track or a band. Great for creating new music as it's so adaptable. Best gadget I've ever bought. Highly recommended.
