I recently received the reverb upgrade mod info from Mark so, if you feel comfy wailing a soldering iron, here's a print of what needs done.

Parts needed:
One 33K 1 watt resistor
Two 1.0 megohm 1 watt resistors
One 220pf capacitor (remove cap C26 entirely if you want a darker sounding reverb)

The final result is a deeper sounding reverb that's less "in the way" so to speak. It's not as lush sounding as say a ÷13's tube driven verb, but not too bad for solid state circuit.

Thanks very much for the info! I look forward to giving this a try. I'm probably going to add a push/pull bright switch while I'm in there. Nothing like making a great amp a little better!

Yup, I thought about adding a pull pot bright switch but I prefer the bright cap lifted.....so I figured why bother at this point. Good luck with the verb mod and let us know what you think when you complete it.

In case you didn't see this when I posted it a couple of months ago, an alternative to a push/pull switch is a chassis-mounted mini-toggle.

Here's a shot of it on my Tone King Continental. You reach around the back to access it. The front of the amp remains stock.

Here's Mark Bartel drilling the chassis for the switch.

And a second shot of the drilling.

Yeah, I did see that thread - it was interesting to see what you and Mark decided to do.

I'm probably still going to go with the push/pull option, unless I can't find a push/pull pot in the correct value and taper (anyone know off hand what the pot values are in there? I haven't disassembled mine yet). This option still seems the best for me - I still have the option to switch the bright on and off, and no new holes in the chassis.

i thought this was a great idea when Vaughn mentioned it, but i was a bit concerned about putting in a different brand of pot because i am somewhat afraid the taper might be different (even if both were log pots). that made me think that the best way to do this is to ask Mark for his source and see if they offer the same pot with a switch. i haven't had time to chase this down yet.

on a different note, i recently developed a Meteor cabinet buzz that came from the one inch (or so) strip of wood that runs along the top front of the amp (next to control pannel). it goes away when i slip a piece of cardboard below it, but i'm beginning to think it calls for a screw or two from the bottom up. i thought i'd mention it in case anyone else develops a buzz ...

Yes, I completed the mod and I think it is an improvement AND different. Like I said in my original post, to my ear, the reverb now sounds deeper and less in the way. Personally, while I tend not to use reverb much, I do like the modded version better.

As far as the bright/pull-pot is concerned....the last time I spoke with Mark, he was looking for a source for the pot so it might pay to sit tight for a while to see what he comes up with. I probably won't add it to my amp because I prefer the bright cap lifted but, then again, I could try a different value bright cap for a less drastic tone shift.

I'm using a 33pf cap now with a switch (stock is 64pf/hard-wired).
