Today I pulled the Custom 5 out of my Mahogany boddied Washburn MG 120 and replaced it with a JB that I swapped in an A2. Instant big time Brown Sound fat warm sweet tones. Swapping the A5 for the A2 in the JB was much more dramatic a change than it was on a Custom wind. The JB A2 output is stillunder the A8 Custom in my MG 122 but they are in the same ballpark.
This thing really sings in this guitar with a BIG warm open tone and it seems to clean up VERY well with the volume controll.
The A8 Custom still seems to be more articulate and much tighter with more output but this JB/A2 is interesting. Tomorrow night I will hit the stage with it and I will also have the A8 Custom MG 122 so I'll give ya an update after that. So far so good and I likes it!!
Here are the guitars they are pretty much identical except for the color and neck pickup configuration.
The MG 120 with the A2 JB
The MG 122 with the A8 Custom and both are 1995's
Here is an identical pair in a Washburn add from 1994 with the specs
