Distortion pedals hand made lamp by Mr. Butler Himself.
Lamp pramp 12AX7 Chinese brand with its built SPECIFICATIONS.
The technology is analog sr, what a question ...

Two models are available: a standard version and a version with a knob of bias for SETTING THE + / - roundness.

A small point ngatif: its size and construction sheet US (adapter US / EU is prvoir)

UTILIZATION

Simple configuration:

Level 1
1 Hi
1 Low
1 Tube Drive
2 LEDs (power and drive)

Manuel? Pffff, no need, but it is still good even l.
Warning! May be asked to build it in 110 or 220V. So I asked a 220V power supply, but we need an adaption prvoir US / EU.

SOUND QUALITY

The key is the highlight.
It is a crunch trs trs drive a shiny british.

Start with standard lace sensor on VOX: trs Its clean, lots of gain
With gibson LP custom of JCM800 lead in: boost without loss of earnings.

A wonderful c'te pedals! Combine with a good GE7 to filter frequencies and the tour is played.

Otherwise, the EQ is effective trs.

OVERALL OPINION

So superb pedals worth its price
Sound of death. Uses, amongst others, by pulse Gilmour on tour.
I just regret the fact that the power supply is automatically US format.
Chandler compares the version, the pedals a lot more gain.
I notice even when it sounds better with single coils plutt with doubles.

Go for it, there are still some new in Butler Audio, but not for long.
