I just recently bought back this amp I got in '82. The high end is very "glassy", I don't remember it being this way. I put new tubes in and that helped. If I turn the master up all the way the treble is alot hotter that if I play it at 7 or below. At this point I can only turn the treble control between 3 and 4 or it will cut your head off. My question is, what does an amp sound like when the caps are getting weak? The amp is quiet, no hum or buzz. | ||

Your caps really shouldn't effect a change like that. Some amps are voiced trebly like that. My 2-10 65 is that same way. Personally though, I've never had mine THAT high! 150 watts wide open? Where are you playing?!!!!!!!! Seriously, you could have a cap going south, letting the world through, but it would be a trial and error method to replace them unless you are able to check them all yourself. Does your model have the 12ax7 PI tube or is it solid state? Mike. | ||

Michael, this amp is solid state on the pre-amp side, and has 4 6L6's on the power side. I play pedal steel so I want it clean. While the master is turned up all the way the pre-gain is only at about 3. However I can back the master down to around 6 and still have plenty of power. I'm just curious as to why turning up the master increases the treble. | ||

Most likely, what you are getting is just the power tubes are being pushed a little harder and the production of more power changes the tonal character of the amp. You may jsut want to leave the treble down and run with it. |
