## Customer Reviews

### ⭐⭐⭐⭐⭐ Works well
*by P***S on 26 February 2025*

Amazing little box that does all it claims to do. Excellent for practice. Sound is clear and realistic. Have used for 4 to 6 hours without any sign of batteries needing to be replaced.

### ⭐⭐⭐⭐⭐ Effective mix of phone and Bass
*by C***N on 17 March 2024*

AT first I was disappointed by relative low volume , but once I got used to it, the balance between phone and Bass signal makes it a very good (silent) practice tool. My wife really appreciates the peace. While the tone is not exceptional, it is a really useful practice tool that I am using more and more. Which is a surprise considering initial disappointment in volume. However, for the price, it is great and if needed I would buy again.

### ⭐ Useless. No volume to speak of and the tone/mix dials do nothing at all
*by F***M on 15 September 2024*

See heading.This product is nothing but a cheap (What did I expect for £16.99?) mixer, which doesn't even do that properly.There is no volume to speak of from my EUB, which has an active piezo pickup and that means that whatever source is used in the Aux socket has to be kept really low.Apart from anything else, the tone and mixer dials do nothing anyway. Probably not even connected.Anyway, I'm sending back to Amazon for a full refund.DEFINITELY NOT RECOMMENDED. Spend a bit more and get a better product.
