Pedal 'classic'. Input jack or canon.
Booster bass.treble correction and effective.
Slight distortion, nice grain. (But I'm using it more since I discovered the Proco RAT ...)
Easy to use.
One defect: the LED remains lit for a few seconds. We do not know 'first hand' if it is on or off.
We must also choose between distortion and boost (by a switch). Can not change while playing.
Effective noise gate (a small knob), can play on the sustain of the distortion.
Excellent pedal but be careful, do not expect a super distortion type 'metal' and so on.
This is an excellent booster, can correct the sound a bit depending on which gear you play.
The distortion is good but 'light'.
I use this pedal to boost clean sounds in 'solo' in clean sounds. This allows me to make a slight variation on the same sound, and slightly increase the gain.
Although ... I've been a ... over 15 years! I do not remember exactly. Anyway, every time I go out someone wants me to buy ... I saw that TC re-issue a similar interface with better it seems. Should try it ...
