-3 Buttons (volume, tone, gain)
Possibility of putting batteries (lasts 15 20 hours).
Super simple setup, very easy to find a warm, round, vintage trs.
the knobs are prcis, progressive and trs.
In this résumé as good pedals.
The is really, really good pedals for the blues / rock, trs warm, round, full of warmth and especially do not drool grows back.
Uses a strat US (single microphone) is prcis, raucous, full of harmonics.
I use a Laney VC30 lamps, the clean channel.
For the critics, I blame him (history of criticizing, right) do not go far enough in the crunch, not to have an overdrive trs muscle to dive into the world of hard rock.
For mtal, this is not the pedals for you.
I also found the price a little nine lev you pay the brand "VOX", luckily the quality is l.
If you are the blues / rock, the investment is well justified.
