Who Knows About Tubes And Amps? Options

[Gabriel Leopardi]

Hello guys. Today I went to my luthier's house to set-up my guitars for the next weekend shows and we have been talking a lot about tune amps, tubes, digital emulators, etc. I told him that I wasn't 100% happy with my Dual Rectifier tone, because I feel that it's a bit trebly and lacks mids. He suggested me to try switching from 6l6 tubes to EL34 to get a fuller sound and more mids. He also talked about other valves that were bigger but I don't remember the models.

Does anybody know a bit more about this?

I'm sure most of this has been covered but I thought I'd share my experience.

I have a Laney GH 50 watt with the same Marshall 1960 straight cab you are using. This amp also has the same feature with the power tube bias switch from 6L6 and EL34. I always preferred the EL34's cause of a tighter sounding crunch like a Marshall JCM. It seemed at least with my amp the 6L6 power tubes sounded too muddy. Also, if you have used the amp for many hours it might be time to change out the old power tubes. As you mentioned it might be a matter of just pairing different speakers that match the amp better.

I also spent some time experimenting with the preamp tubes. I used some different style preamp tubes that I mixed and matched. Tried them in different sequence and found that you can achieve some nice results in changing the sound. I have 5 preamp tube slots in my Laney and one is for the effects loops. The effects loop required a ecc85 to work best for mine. Experimenting with the preamp tubes i found can change the sound of the amp more dramatically then even the power tubes.
