Review: Small and versatile Works with 48v Phantom Power - It is a very good and versatile preamp because it works with phantom power, too. I returned the first one due to noise, but it turned out that my house had some issues with the electrical framework. I bought it again. It is small and very useful. Sounds very good too.
Review: Great all round. Big clean sound boost. - It brings an old bass cab to life, very clean sound no buzz with a big sound/volume boost. Small and compact, easy to carry with a strong build quality. Spread over a few payments with a good discount it was a very good buy.

*by M***X on 1 November 2015*

Awesome pedal, took a while to arrive and I did pay for express delivery!!! But the pedal is great, easy to use and you can get pretty much any sound you want out of it. Haven't tried it in the studio yet but I use it for all my live gigs, I've set it up for an awesome slap sound but I pretty much just leave it on most of the time coz it sounds great!!!!
