Best for the price

By Gibby McFender

from All over, TN

Has all the features I was hoping to get in a unit that's very reasonably priced. I can't believe the sound quality of this unit. It seems as close to transparent as you can get. Gold connectors, strong signals, true diversity, more than a football field of range... I'm thrilled with the 3500. The only thing I wish were different is the body pack, I'm afraid that with time, the battery compartemnt door will wear loose. That's a small gripe and the only one. Just take the time to set it up properly (10 minutes tops) and you get more than what you payed for! Highly recommended.

Not bad for beginners

By Theaxmandomain

from Montgomery, Al

I purchased this unit on Friday and returned it on Saturday. Overall, it works well, has an input gain pot on the transmitter and an adjustment tool which is good. There is also an output level. The main problem with this unit is obvious if you play through a pedal or multi effects. I would get the levels set on the xmtr where all was sounding good for a clean setting, then when I would switch to a distorted patch on my pedal, the color of the sound changed dramatically from what it would be with a cord. If I then re adjusted the input level on the xmtr, it would sound acceptable. The problem here is of course that you can't very well make this adjustment while you are playing. If you use the same type of sound all the time or are not very critical about the reprodiction of your sound, this unit will do just fine. I have traded this unit "up" for a Shure PGX and will soon write a review for it.

Great Buy.

By Phillip B. Holmes

from Plano Texas

Great unit hasn't dropped out even once and has a good range. The only thing I didnt like is the flimsy belt clip on the remote pack and the fact that the body pack is made of plastic. That makes me a little nervous. Have owned it for about one month and no problems or breakage so far. I've dropped the body pack a couple times and it seems to be holding up.

This was the first wireless unit I bought so I wasn't too sure what to expect and what not to. I bought it in June of 2009 and have used it ever since, it only took some slight tweeking with my EQ on the amp and the gain adjustments on the transmitter and everything sounded perfect in my ear, I've never had it cut or drop out while playing, it's got great range, I was messing around one day and walked around the block andonly got a slight delay in my sound. I've used it live many times and normally practice with it. I use it for a bass and it transmits my low end amazingly. I think it was worth the money.

Not worth it

By Benjamin D

from warren, MI

I got this wireless system last week its not what i expected i used it and it makes my amp more high gain doesnt give its original sound as if it was plugged in with a cable. I also cuts out in the middle of playing and its annoying i give it a 3 not what i expected at all very disapointed



By mrhat101

from CO

Fantastic unit. My only problem with it is that the body pack is plastic. I wish that they would have made this out of steel like the rack unit.


really good

By steven

from california

this system was really great. just got it as a gift for christmas and its amazing. i tested it out and was able to walk down the street about 100 yards before it even started cutting out. i give it a 5/5 stars because there was nothing wrong with it (as long as you don't switch channels). makes you look like a pro playing live too. i just hook the transmitter on my back pocket and its good to go. fantastic.


What more could you want.

By Lyndel W. Carpenter

from Defiance, Ohio

I just bought this wireless system today at Guitar Center and Giged with it tonight. All I can say is WOW this thing ROCKS. The sound is about as close to a cable as you are going to get and the setup was a no brainer, put the batteries in, pluged it in, adjusted the gain on the transmitter reset the EQ on the amp and we were rock'n ten min. tops. No dropouts all night long no static no pops no noies just pure clean tone. I do not know why anyone would want to pay more for a wireless system.
