I have an IBANEZ ARTIST AS 50, 1982, purchased in 1982, Japanese-made. Despite his 25 years, it remains a superb scratch (so say those who saw it)
22 frets, super 59 pickups neck and bridge.
QUICK easel ... sorry I did not know too much. 1 volume knob and 1 tone knob for the microphone. I play jazz, bossa nova.
D handle fairly large but very comfortable, very easy to acute attacks: with a proper adjustment of the bridge is reached supersonic speeds.

I plan to replace the pickups with Gibson Classic 57 to sound for a little less acute. But I am afraid to do something stupid: so if an expert could give me his opinion? Thank you in advance

UTILIZATION

The handle a little off is very nice: the highs are easy to access. Given the build quality (violin and hardware) its weight is correct. Good ergonomics.
For good sound, to look for a bit.

SOUNDS

For jazz, blues, bossa nova, it's great. This guitar is versatile, can play rock as well.
FENDER POWER CHORUS I use one and a Peavey Classic 30.

OVERALL OPINION

I am very pleased with this instrument. Excellent quality / price ratio at the time, today it has gained value.
You can play everything.
Without hesitation I would do this choice.
