Lonestar Effects Loop Buffer

Post by micky mesa » Sat Dec 23, 2017 11:34 am

I find the Effects Loop on the Lonestar to be sucking tone out of Clean playing I find the 4CM to be affected
I have went back to using the front of the amp without the effects loop better headroom that way

I can see from the version 1 schematic they some what altered the circuit compared to the Mark I reissue, and some of what they did can squash the signal a bit killing the transparency of the tone, as some loops can. I will be making some tweaks on my version 2 to try to remedy it to a acceptable level. But I need a schematic for the version 2 with 100, 50, and 10 watt settings, as the seller did not inform me it had issues due to plugging a power tube in with a broken key pin, causing circuit damages... they have zener diodes that squash/compress the signal and a local feedback network that limits the high frequencies to where it also kills some tone, trying to not overload the effects. My old Reissue mark I was fine without the extra smog crap. So I am thinking, remove some of the components that are not in the reissue and see how that works and go from there. If your interested I will follow up on this when I can.

You’re right about the screw around, but fortunately I’ve owned the original since new and no problems.
Only easy tips I picked up off Andy Timmons, was run the fx-loop level at around 1 O’clock, and try some tube swapping. I’ve used JAN5751’s and 7025S with great improvements, the 5751’s liked around 2 O’clock.
I also found a particular brand of pedals didn’t like the fx-loop
