My question is on my 100h. When I use the od American preamp the bass control does not work rite.
Seems that from 0 to 5 on the bass pot there is little or no response but when I go from 5 to 10 the amp gets very thin and sounds like the mids are cut vol seems to drop a bit too.
Only seems to happen on the od American preamp. On The cr American preamp the bass pot acts normal.
Anywhere would be great
