For the price, it does the job.

Absolutely awesome effect pedal! I tested it on a jcm900 and a vox ac15. If the idea is to boost a clean sound, the result is very convincing... if it's to boost amp saturation... directly it adds gain and a bit of level, but in the effects loop it has a formidable result!!! So for my marshall it's perfect... for my Vox it's a bit less effective but... I want to say, it's like all boost pedals directly... Using the neutral boost or with added gain is very nice... I am extremely convinced, it's better than 3/4 of the boosts I've tried and very often for half or even a third of the price!

very good with clear sound
