I have been a bass player for several years and I had used a change a lot of diffrend equipment. I use my Orange with Fender American Deluxe thru Orange OBC410 and it sounds amazing. Orange can really produce diffrent tones and it is a powerful amp.
The construction of the head is like a tank. It is very well made and a beauty to the eye. Only bad thing is, that the amp weights a tone! (24 kg).
I play diffrent styles of music. From funk, jazz, rock, electronic, metal,.....and the EQ on the amp is very responsive at changing diffrent tones and more fat heavy sounds with a bit of heavy gain or light jazzy sound.
The amp is powered with 1x ECC83 & 1x ECC81 preamp valves and 4x 6550 power amp valves, which produces a really great sounding, In 8 years I STILL haven`t change them becouse they are great.
If you are thinking of this amp, just buy it.
