I recently got a Marshal JCM800 2203 reissue and it sound unbelievable! But I seem to be having issues with the FX loop. When the FX loop is on the
-10db setting (which is recommended for floor pedals) The amp seems to be noisy... but if I set it to
+4db (chich is recommended for rack units) the noise seems to go away.
The problem is that I am only using this FX loop for floor pedals. (A Boss DD7 and a ISP Decimator G-String II)
Even with the noise gate, the hum seems to come through. What could cause this to happen? Is it typical for an amp to be noisy when the FX loop is set to
The effects seem to sound okay when it is set to
+4db, but I'm wondering if this is typical or if I should bring my amp in to a technician and have it checked out.
