I bought the Tube distortion pedal first and it made me get rid of every distortion pedal on my board yeah it's that good almost toooooo good. Very powerful so you need to dial it in. I just got the overdrive pedal yesterday and not surprised it is just as good. I use these through my 2 1978 Marshall 50 watt heads and it takes them to a new level. The overdrive is so nice and warm and the distortion can just melt your face if that is what you want. These pedals have so much flexibility the controls actually work! Guitars look good also but I have 27 guitars and my wife will leave me if I buy another….GREAT tube pedals buy them well worth the money!!! You can get any sound you want, even using them at low distortion level creates this sustain and smoothness…..rock n roll!!
