MESA LONE STAR...VERSATILE , GOOD with PEDALS of ALL kinds, PLENTY of POWER with VARIABLE POWER settings ( 10-50-100 watt settings ) it BOOGIES !!
I agree, it's a really nice amp (I've got the 2x12 combo, 100 Watts, and my son tours with one), but Tex said he tried it and it wasn't for him. And really, he has something conceptually similar with his Bogner Shiva.
Though in my humble opinion, the LS sounds best if one takes a lot of time to set it up and experiments with its many controls, am I right? It rewards the patient amp twiddler/tweaker more than some amps.
Personally, I like it best at its 100 watt setting, solid state rectified, with the Master volume and effects loop off, so the sub-master volume for each channel controls level. With one less signal path stage, the amp sounds a lot purer, and closer to a hand wired amp - in fact, I think it competes very favorably with my hand wired amps once this MV stage is eliminated.
I also run my Lone Star with a Furman P-1800 PFR power conditioner that has a 45+ Amp power reservoir. For whatever reason, the amp sounds a LOT better running with this power supply box; the theory is that it can supply power to the amp faster than the wall socket. And with a 100 Watt amp, it seems to matter quite a bit! In any case, this unit has proven its worth, as far as I'm concerned, and I'm going to add a second one for my studio monitors.
Recording with the Lone Star, DG30 and HXDA last fall; the Furman power supply is on the stand to the right of the pic with the blue light on:
