A boost based on the Dallas Rangemaster 60s, and fully analog with germanium transistors.

UTILIZATION

With a "volume" and a 3 position switch (low / mid / treble), it is very easy to use.

SOUND QUALITY

This is not a clean boost or overdrive, AC can boost certain frequencies with gain and a lot of heat, it's been really sing an already overdriven amp or pedal type fuzz, overdrive etc ... it also works to clean to "crunch" sound but not his chosen field.
The choice of 3 frequencies (mid / low / treble) can adapt the sound to the amplifier (british / us) or the guitar used (single coil / humbuckers).
With this pedal, the sound of harmonic throat, gaining in thickness and presence, a must for the soloist.

OVERALL OPINION

It's really a great "boost" that can sublimate saturated sounds, especially in the solo game, an area where it warms the sound, and really gives the impression that the amp is pushed to its limits.
Not to waste anything, the pedal is very quiet, which is no mean feat when you see the number of db of boost!
