  • Mesa Roadster Ch2 Issues

    I recently picked up a Mesa Roadster for cheap because of the issue with channel 2. The issues is when you adjust the gain it seems to go crazy until about 50% then just dies. I’ve probed around a bit and everything checks out on the board. I haven’t measured the gain pot yet. It’s at my rehearsal space and it didn’t dawn on me that it could be the gain pot till later on. Also it seems like it may be affecting the whole amp. It doesn’t seem to have as much gain as it should for a Recto. I’m running the gain on about 8 on channel 4 and still need to hit it with my TS9 to get it heavy enough. I checked the tubes and gave it a good cleaning with deoxit too. All the voicing switches seem to be working properly on ch2 also. Thanks for looking.
