Righto, well i definately have sound now, where i didnt before 👍👍
Using Pre + Mic then Pre + Line - too quiet as you foretold. All ok apart from the Volume
Using Post + Mic, ok. Using Post + Line, loud buzzing.
This is with all EQ set flat, ( apart from Freq knobs ), and bringing gain up while Channel Vol at 1.00
With bass plugged in the GB, but not played, the buzzing gets louder if i turn up either CH 1 Gain or Ch 1 Vol ..or both
Sound file attached. You can hear the open E initially + buzzing. The buzzing appears to get a tad louder, but its just the bass note fading making it seem louder
