GK Backline 115's ... Can Anyone Identify These ?

[tomana]

for the GK Backline 115 I came across three different fonts and two different colors schemes. It's the same model. What does the font and/or color change indicate, what year or years that particular amp was manufactured?

The top is the newest I believe and the middle the oldest? Email [email protected] or [email protected] with the serial numbers they can probably tell you the years.

I also think the top is the newest so the third one down has to be the second oldest because the font is the same style and the second one down must be the original release. That's all I needed to know and thanks for the contacts {8^D
