A-level
A drive-
One-tone
- Much of its sound !!!!!!!!

UTILIZATION

Easy to use, it serves as a crunch amp, or boost
to have a tube amp

SOUND QUALITY

Then the WOW !!!!!!!!! this is the overdrive overdrives, I have tried many ... but the sd-1 has almost make me cry. sound and still sound
this pedal is much better than the ts-9 and all other model that costs 2 3 times the price of a sd-1

OVERALL OPINION

I use it for 3 months and I will keep forever
probably the best value on the market
and probably the best overdrive in the market full stop
tried .... you will not be disappointed
