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 not ear fatigue, I also have in my rack my JMP1 which does not do that.
Tubes being out of discussion, I would guess that a particular electronic part gets too hot and changes its characteristics. Any idea what is going on here? The preamp does sound out of this world when in parameters so to speak.
Thanks, Adrian
