It is a Treble booster pedal became very rare, despite its reissue in the mid-90, the date of my 70 years.

level of connectivity, is simple: an input and output!

UTILIZATION

The use is bone simple:

Three knobs, treble (treble), bass and volume boost.

Including a pedal used by Status Quo (Francis Rossi and Rick Parfit) and David Gilmour (Pink Floyd) The Wall period.

SOUND QUALITY

This booster is amazing: it is certainly the most powerful ever made!
I read that he was able to increase 70% gain on your amp.

Indeed, when the volume knob is set from half an overdrive pedal delivers highly effective!
Up to 100%, we are dealing with a Fuzz pedal, while drooling.

A tip if you play in apartments: Power boost when the volume will be set at 50%, make sure the volume on your amp is almost a mini, failing to finish taped to the wall.

Best used with a tube amp is that it excels in these conditions.

OVERALL OPINION

I use it for almost a month, and has become indispensable in my set.

Strengths:

The look, sound, efficiency, ease of use.

weaknesses:

No power adapter! 9V battery operation requires.
Access to the battery not practical
Size: a large pedal!

These pedals have become very expensive, because of their rarity. Although the effect is worth the time I think the price is not always justified ... beyond 100 euro, think a bit anyway.
Otherwise, I would do this choice without hesitation.
