Re: Marshall jcm 900 hi gain dual reverb 50w folkesson mod b
låter väldigt likt vad denna enkla moddning gör:
"Applies to the 4100 and 4500 models.
1. Remove R7 and R43.
This disables a hardwired tonestack on the gain channel. This tonestack scoops mids, changes the low end and makes the amp sound harsh and sterile.
2. Place a jumper wire over D10.
This will give a smoother, warmer and more organic distortion on the gain channel. It increases the clipping a bit.
3.Jumper C27. Restores the low end."
lätt att återställa om du kan löda lite
