I don't know if I haven't noticed this before (likely), if it's somehow more noticeable at quiet bedroom levels that I'm playing at nowadays (unlikely), or if something's goofed up with either the MKV or the GSP1101 ( :!: ), but there seems to be a fairly drastic tone EQ shift that occurs when the MKV signal goes through GSP1101. 
I used to think that this FX processor has overall good build and low tone suction, but now I'm not so sure.
Does anybody else have GSP1101 with their MKV that can try this for me and tell me how your experience is? I would really appreciate it.
Let me explain further. Here's how things are configured:
1. GSP1101 is attached either via 4CM or just in FX loop of MKV (doesn't matter, both ways exhibit the problem), and the corresponding GSP setup wizard configuration has been performed to let GSP know which way to operate.
2. A "blank" custom patch is used that has each and every option (OD, compressor, delay, reverb, EQ, etc... EVERYTHING in the patch itself) turned OFF. But the GSP is NOT in bypass mode--it's just passing the signal through the patch without applying any effects whatsoever.
3. The global EQ in GSP1101 is zeroed out.
4. The volume levels have been calibrated so that they don't [noticeably] change if you were to turn on and off the FX loop on the MKV (with the footswitch or with the loop assign knob in the back), thereby alternating between passing the signal through GSP and NOT passing it through GSP. The point is that the GSP1101 doesn't make the signal quieter or louder when compared to just the MKV, with all else being equal.
Now, here's what's happening... When I put the GSP1101 in BYPASS mode (by pressing the BYPASS button on the GSP itself), the tone sounds natural and completely unprocessed (as if there were no FX processor in the loop). If I disengage the bypass mode, the tone sounds like it gets a pretty horrific EQ shape, sort of scooped but kinda honky too. Almost like a stuck wah pedal sound. It's barely noticeable on CH1 on clean unbroken-up type stuff, and it's moderately noticeable on CH3 although somewhat manageable. But on CH2 it just destroys the tone. Just bad.
Here are my channel settings for reference:
CH2
Mark I mode
Any wattage (let's say 45, diodes)
EQ = ON, PRESET, 12 o'clock
GAIN = 2 o'clock
VOLUME = 10 o'clock
TREBLE = 1 o'clock
MID = 10 o'clock
BASS = OFF
PRESENCE = 2:30
THICK = OFF
I can try and do a recording to show you what I mean... But what I most need right now is somebody to check if this is happening for them too (if I'm lucky enough to find someone here who also has a MKV and a GSP1101). If not, I would be interested to see if you can do a test through a G-Major or something similar, if you have it.
