5 from 5 Really improve your sound

Easy mounting, great sound & possibilities.
You need to add a knob and an enclosure. Everything else is in the kit included. If you are a bassist you better add three mkt

5 from 5 Facile et utile (easy and useful)

Montage simple à réaliser et pratique car je cherchais à garder mon octaver clean tout en utilisant une disto. Pour gagner un peu de place, jutilise des jacks stéréos pour les boucles auquelles je branche des cables en Y (stéréo 6,35 vers 2 monos 6,35) et comme ça tout tiens dans un boitier de type 125B, je peux même ajouter une pile 9V.

Easy to do and useful to keep my octaver clean while using a distortion. To save a little space, I used stereo jacks for the loops and I plug a Y cable ans everything fits in 125B enclosure, even with a 9V battery.
