Hi, Just as a note.. when reading about the reader mod 2 ( jumper mod ), I noticed one one of the noted results was that the tone stack when all dialed 'off' filtered the volume to zero... my 07 LSC mk 2 does this as standard !!! ?? .... interested to hear any input from others ? Paul

And just in case you do have tube probs... SOUND “DROP-OUTS” / INTERMITTENT SIGNAL One Possible Cause Most (but not all) Mesa/Boogie amplifiers have one or two “cathode follower” tube stages in their preamps. Tube selection is CRITICAL in these stages. Specifically, in a 12AX7 tube...

Hi again Fuzzfreek, Other obvious checks... but ones that have been missed by others, including me, so its worth going through it all. firstly, loop volume (send level) on the back of the amp should be at around 12 - 1 oclock. your problem is intermitant, so I doubt this is it.. Im sure you...

Hi Fuzzfreek, Have you tried jumping the loop with a short patch cord to see if the problem dissapears. the loop inputs can cause problems if they are oxidised or dirty. plug a patch cord in and out a few times then run the amp with the loop engaged jumping send & return with a good patch cord...

To all concerned..... Just wanted to drop a belated update. Messa took my LSC back for a full health check. I had to wait a couple of weeks. They replaced the reverb tank... and its now working perfectly. Thanks for the help everyone. Paul.

Hi everyone, Most switches build up static, upon first used each session my lonestar channel/solo & 100/50/10watt switches popped so loudly it almost left me not wanting to use them without turning the volume/output way down. solution... it was static, I just switch them a couple of times...

Thats great news stonevibe, well done. :D Paul.

agree with pine... think this came about as a potential fix for volume drops outs due to poor/dirty contacts inside the the loop inputs. presumably send & return are bridged internally, if the input mech contacts arent spot on, theory is its possible when no jacks are in loop this may cause...

Its very easy to sound condesending or abrasive when posting when in reality your not intending to. ( we have all miscomprehended the odd text message ) .. if someone says something in person we can see their face and pick up on their intention. I could have been indignant ( ie, he thinks Im an...

Thanks for your input ifailedshapes, Its definately not the condition of the power supply. I checked that out ages ago, I have used many valve amps over the years, this particular amp is definately problematic. It has a suspect reverb, wanders off settings and blows pre amp valves irrespective...

UK price of 2x12 LSC £1799 ($3,065.89 USD ) !! So after a great deal of time spent buying & replacing pre amp tubes that keep crapping out, then spending even more time recently trying to improve my somewhat absent reverb, I now find after having used the FX loop hooked up for a while. when I...

dougbilski, I just found that pic on the web when researching what the screw does, not had my chassis out. so Im not qualified to help, other than presume the top of the screw tightens against a foil sheet on underside of the cab top. Paul.

The screw in question.. just to clarrify... :) on second pic, you can see the top of the screw has a grounding plate to make good contact with the shielding above.

Hi Seymourstilleto. Just follow the basic rules. then experiment. Ive settled on this after years of messing. tuner> true bypass box in > send > wah ts808 BB pre amp DS 1 74 vintage P90 > true bypass return > out > Lonestar FX loop send > MXR Stereo Chorus > EHX Deluxe Memory Man > Boss...

Hi guys, So what do we all make of the mesa memo (posted elswhere on the board) stating that russian 2's are NOT reliable in cathode follower positions... having read the 'memo' I put a known good mesa chinese 12ax7 in V3 of my lonestar.. It lasted less than half an hour. now back with a stock...

Hi JAZZGEAR, I meant the settings not the amp itself :) but yeah I'm sure your right nitrous2400, (combo on the other pic.) Thanks for sharing. Paul.

Hi nitrous2400. Was this after or before he played ? .. Ive seen another pic elsewhere of this giglet, and his setup, but his lonestar has been tweaked somewhat, the other pics are somewhat different settings, did you see him tweaking......

Stonvibe, No problem, This forum has been so informative it felt right to share the info. even if it's not much of a help :) If Im honest stonvibe.. ( and I'm not trying to upset anyone here ) .. I spent years trying to find a good replacement Les Paul in the UK that wasn't in some way...

Sorry.. gremlins somewhere !
