Hi all,
this is my first post, although I have a Triaxis, a 295 Simul Class power amp, and a D180 since long...
BTW, this means that my only contact with the venerable Mk series is through the Triaxis...
I just got a Quad Preamp this week.
I compared Rythm 1 and Rythm 2 tones with all knobs at 5.
I noticed that the "Rythm 2" channel as really much more bass than "Ryrthm1" (with the same knob settings).
Using a Les Paul neck pickup, I get a very deep "jazzy" sound (if gain set right).
Indeed, I did all the usual tube swaps... (and knobs push and pulls).
Is this tone difference normal, or should I search for a possible problem ?
Thangs in advance !
P.S. Based on the schematics floating around, the Quad Preamp "Rythm 2" looks a lot like the Mk III Red stripe "Rythm 2" (around the 3.3M resistor between the MkIII V1b and V2a).
In "Rythm 1" mode, both have a 470k going to ground, that effectively reduces the low frequencies.
