Great build Xtian !
Martin's Presonance is a great addition - glad you got it sorted. I won't use a regular presence again. For a few cents it gives so much more flexibility.
Worth noting - if you do get oscillation at the pot's extreme travel, just add a resistor (10% of pot value) to the outer pot lug. I've never had to do this, but some of the guys have.
Presonance was re-named MARTINIZER on my amps. Many thanks to Martin for this.

Hardwood valence mockup shown. I want to cut the Hebrew letters out. Anyone can laser this 5/16" walnut/maple for me?

Wow, you moved rather quickly on this, huh?? Maybe its just that I'm really slow... Really digging the looks all around, very nice!

I've got a future project with the Martinizer in mind for too... Can't wait to see the finished product! Sexellent work. ;)

I decided to do two-tone tolex (cocoa and black) with piping on this cabinet, since I've never tried.

I could certainly use a CNC machine to cut the logo on the valence--anyone can do?

Thank you! I have not seen Equilibrium--will check it out.

Nearly destroyed my valence stapling the piping to it. Damn staples are not cool for walnut edge grain.

I watched Equilibrium. That was a lot of bullets!

After struggling with the Presonance control and associated lead dress, I finally gave up and returned to stock presence. Was having high pitched (but audible) oscillation that I couldn't tame. Changed the dual bright caps to 47p and 100p (the 500p was way to bright to be useful). Finally, found a matched set of Hammond EL84s, made in Holland. Wow, amp sounded great! Then took it to band practice, my buddy played it, and took it straight home and is considering buying it. So, good news, bad news, good news.
