I bought this a long time ago and this pedal does what it should do.
Very nice and smooth drive, very much like the pedal it is supposed to sound like when used before a pedal or before a tube amp.
Of course there are small differences (I compared it to my MAXXON OD808).
I use this pedal on my small pedal board I use for rehearsals and sometimes at home, together with a Bugera V50 or Blackstar HT-20.
The Maxxon is used with a Ashdown Fallen angel or Marshall JCM800.
Although I did not A-B the Maxxon with th HB, I am very happy with this pedal. (I only compared it by ear).
About me:
I play approx. 20 years, main guitars (too many, according to my wife) are Ibanez, most are fitted with Dimarzio Pick-ups.
I play the (only) guitar in a rockband.
I have had many many pedal in the road, searching for "my sound" and the Maxxon or the HB play an important role in this sound. (boost function with very little drive)
