New GK Plex Preamp

#44
The photo in the OP is slightly smaller than it would need to be for the XLR plug to be correct so it's pretty close. What I'm thinking here is, you might be able to get a 'two channel' switch going like on the GK 550 Fusion head. Use your GK fusion 500 or 800 with EQ flat but running gain hot for the tube distortion. Switch the amp back to second channel running clean but EQ is still flat. Then quickly tap this device to set a different EQ for a different tone. What else can you think up based on what we're being shown? The 550 Fusion retails for $1050 w/two channels. This running through a MB 500 Fusion head should retail for $900 - $1,000. At that price I'm going for the 550 for ease of switching channels - but going with this and another MB amp for light weight and ease of transporting - 28 pounds vs. 5 pounds.

I'm gonna hazzard an educated guess and say that the Symmetry knob is a blend between Single ended distortion and push-pull. It's an idea I've had before (for guitar, not a fan of distorted bass) - run push pull distortion, and just take a balance pot to blend between all push pull or all single ended. Push-pull results in cancellation of even harmonics which were generated in that distortion stage.

I wonder if all the pots are stacked. That would explain the dual functionality and the fact that the blue line isn't in the same position as the white line on some of the controls.

The knobs look like buttons as on their MBF800 heads. Toggle on "Contour," or "Voice". It also appears to have a cabinet sim(please)?

Not sure you'd access all those features with just 2 switches. Comp/tuner on one switch? Also doesn't seem to have a bypass mode.

Likely the Comp on/off is a tap and the tuner mute is a hold - like all the little digital all in one thingies - think of the little zooms - you can change patches (up OR down), turn the whole thing on and off put it to tuner/mute mode all with two buttons.
It means 10 minutes learning curve, but once you know it - it's easy and fine.
I really wish that Zoom would make a modern and "pro" version of their old 505 era pedal - it was everything I ever needed (and a whole lot more) it was just the quality was low. For the record I basically used it as a comp & noise gate with a tuner built it - but I did keep a couple of patches in either direction of my playing patch that had a bit of chorus or whatever on them in case I needed them.
HEY GK! If you put a noise gate in (say with internal trim knob and a toggle on the face, this would be PERFECT.

I'm guessing here that those are not simple switches. I guess these are buttons like those in the BeatBuddy that recognize short click, long click and double click... Maybe you can eveb bypass the thing clicking both buttons at once...
