The Boogie Board

Hey all.
I recently bought a Lonestar 2x12. I absolutely adore the amp.
Problem is just this past week the power (volume) in the clean channel has dropped about 50% and sounds terribly thin.
channel 2 sounds normal.

I tend to run the gain pretty high on the clean channel.- I love how you can keep a nice clean sound but break it up if you hit it hard.
Any Ideas what might cause this? - pretty much stay in the drive/thick/tweed settings.

I would naturally suspect tubes.
I have a couple of replacement 6L6s I could try, but can someone tell me where they go? (which tubes are for which channel)
Love to have some help. miss my sound - got a show coming up.
Thanks..

Addendum...
I just changed out the 6L6s.
No change...
could it be pre-amp tubes??

Most likely a bad preamp tube! Did you bought the amp new or second hand? If new and not a half year old you should contact Mesa for a new set of tubes!

Hi. - thanks.
Bought it used.

yep, I changed out 2 preamp tubes.
Seems to have restored the volume and tone.
Thanks - Love that amp
Now if they could just make the dang thing lighter. LOL

In the process of troubleshooting it I learned how deep the science of creating tone with tubes goes.
One really has to know quite a lot to expect the amp to perform at its best.

Your welcome and good to read you solved the problem! I've got the head version which is not that heavy Great amp indeed!

I had a custom combo cabinet made, just wide enough for the head and reverb tank. Cut the weight in half and it is now a 1x12 grab n go combo with monster tone.

Yep! Also i don't like Mesa's C90 speakers which come stock with the LSC combo's. A separate cab is your best bet and you can always switch later on if desired.
