AKG WMS 40 Mini Instrument ISM1

I ordered this item approximately a month ago, which arrived within 4 days, great service. I found it easy to set up within minutes and was very impressed by the quality of the product. The transmitter was sturdily built made of a strong plastic. I very much liked the detachable cable from the unit to the guitar making it easy to transfer if necessary to another frequency unit if required or even another guitar via the same strap if you use strap-locks on your guitars . It has built in battery indicator led to let you know if it requires changing, there is also one on the receiving unit. The battery is a "AA" size which with over 30 hours use is still going strong . I also like the mute switch which is combined in the on/off switch, very convenient.
The receiver unit is very robustly made of metal with as mentioned previously a battery low indicator led plus a "pairing led to indicate you are connected, and another power on led and switch. I personally could not detect any loss of tone or volume after I set it up. The range was excellent which would cover a large stage with no problem. If any improvements could be made, I would say perhaps a detachable transmitter aerial would have been nice for convenience of safe transportation. A thicker lead to connect to the guitar would have been a bonus to minimize any breakage that may occur through rough handling .
All in all a great product. I would certainly recommend to any guitarist considering going wireless. Backed by Thomann 3 year Guarantee and 30 day satisfaction, Why buy from Thomann..because I have bought from this family run company before who is always my first port of call when I wish to purchase equipment, I am NOT affiliated to Thomann an any way, but always found them to be totally reliable!

I have 2 of these. I use one for a keytar and the other for an electric violin. I've never had any problems with range or sound quality. I have the one on my keytar tar clipped onto the strap. I have the one for my violin clipped on to my belt. The only draw back is if I'm playing at a venue where there's a frequency clash between the house PA mic and one of my wireless systems. I just go back to using a lead, this happens very seldom. Apart from that its fine and good value for money.
