UTILIZATION

Very easy to use, beginners must adapt or example it is a bit subtle when you do not know much but once understood and mastered it's candy

SOUND QUALITY

The sustain is trs effective attack gives a beautiful shape to your sound, it can be a good boost trs also a tube amp.
when you put a lot of sustain it dvoile your guitar in a different way each movement is dtailll everything sounds more, well I think the only person who does, not because apprcie that it make too many mistakes and he too heard their fake note. Ideal for rhythm as well.
the sound is really a gem

OVERALL OPINION

I have 2 years, and I use a whole day, it's simple gives effective sound much richer a guitar. It compresses the Fawn wonderful rhythm it gives a lovely sustain the lead.
is a short pedals of choice. I would do the selection without a doubt. I tried MODEL custom shop that costs $ 250 like those of clapton, clapton and love, but the boss satisfies me more
