Lonestar Special rectifier tube mod

Hello, My Lonestar Special keeps burning the tube rectifier and fuse. Every other week or so. I understand that Mesa offers a mod to avoid this situation but I am not in the position to send the amp to Mesa for modification since I am in Romania. I tried various tubes, I ordered from TAD and they kn...

Re: Lone Star Reeder Mod #1: Channel 2 Pot-Swap

To me, the most shocking experience was to see that the clean channel and the drive channel sound the same if the drive is disengaged and the Thick/Thicker/Normal switch is in the normal position. And of course, it became hard to get a sound that I actually didn't like. I have no idea how this can b...

Re: My Mesa Studio Preamp does a weird thing

In the mean time I installed a fan inside. Kept it on for 2 hours, no change in the sound, it is perfect. I also talked to a friend of mine who knows electronics, he told me that the culprit may be a tantalum capacitor in the cathode bias that changes capacity because of the heat. The fan is silent,...

My Mesa Studio Preamp does a weird thing

Hi guys, My Mesa Boogie Studio Preamp sounds superb when I first turn it on and it does sound good for at least 20 minutes or so. After that, the lead tone changes in that the low end gets really undefined, I loose attack and bite. Clean tone remains ok. I changed a lot of tubes, pretty sure it is n...

Re: Lonestar Classic - too much bass on drive channel - SOLU

Hi, Unforunately I only know that the capacitor in question (the one that my post is about) is a ceramic 1000pf or 1nf. The original capacitor is 5nf 600 volts so the new ceramic one should have at least the same voltage rating but I think you will be fine with a 800 or 1000 volts as long as it isn'...

Re: Mesa Boogie Lonestar Classic Combo w/EL34 - Tighter bass

I haven't tried other than 6L6's tubes but I can tell you that changing the capacitor at the input at the drive stage like I did and explained in my posts will not change the clean channel at all. Yes, Lonestar classic cleans are beautiful but sometimes they lack that hugeness... My way of dealing w...

Re: Lonestar Classic - too much bass on drive channel - SOLU

Just a quick report on this topic, I modified all my Lonestars, including the Special. The 1000pf (1nf) capacitor seems to be the best. So, the one with the 1nf capacitor gets played the most. Not because the others don't sound as good, I can always adjust the bass to my liking. I tried the original...

Re: Lonestar Classic - too much bass on drive channel - SOLU

No, the disc shape pale orange capacitor that you see in the above pictures is the capacitor that replaced the original. The original looks like the other bright orange tube like capacitors that you can see around the disc shaped one. Indeed, the value of the original capacitor was 0.005uf or 5nf if...

Re: Lonestar Classic - too much bass on drive channel - SOLU

Here it is. The track is recorded in the following way: PRS Custom24 HFS treble and Vintage bass - Lonestar - Suhr Reactive Load - Apogee Duet - Logic Pro with Torpedo Wall of Sound plugin. The plugin is an impulse loader. I loaded a Mesa 4x12 from Ownhammer. https://soundcloud.com/adrianni/mesa-dri...

Re: Lonestar Classic - too much bass on drive channel - SOLU

Hi, I will post an audio recording with both the Lonestar Classic and the Special. I modded the Special too for the same reason, too much bass on the drive channel. I know what you mean when you say thick distortion and I believe this mod actually improves the "thick part" of the drive channel givin...

I thought I should document this for anyone who would like to modify the Lonestar Classic head or combo to a more manageable size and weight.

Lonestar Classic - too much bass on drive channel - SOLUTION

Hello, Sorry about the length of this topic but I think it's worth reading it. Here goes: My Lonestar Classic - short head, beautiful cleans but unfortunately I was never able to bind with the drive channel. It was simply not possible to reduce the bass as much as I felt it would have been necessary...
