US-made Phillips-Sylvania ® 6021 dual triode tubes.
Great for country, blues, surf, classic rock.

Basically: Pedal-amps 2 channels (overdrive and saturation!)

UTILIZATION

Nothing is easier in use!

SOUND QUALITY

I use a stratocaster emg Gilmour + kit and a Fender Blues Junior!
it sounds to hell
The overdrive channel is very warm and with the gain knob to 1 hour is a really happy, the sound is crunchy and warm while being precise!
The lead channel allows a sound to Gary moore ie very hot, very fat and with a substain sick!
Personal love and the price is incredible!

OVERALL OPINION

I use it for a few days and it's up to play blues / rock with a sound efficient! The sound is really warm and fat and substain amazing!
I had a Soldano sp77 and before her, even if it is vintage, quality is near!
on the other hand, it's not very versatile and if you push too much gain, the sound becomes less accurate!
We must find the right settings!
I remake that choice again!
