GZ Add-a-Stage

[RedPlated]

My site is updated with lots of info and installation tutorials for the Add-a-Stage extra tube stage PCB. It's a killer way to add another tube stage to pretty much any amount amp with room for it.

That would be killer !

That would be killer !

I have a guy interested in the amp, if he doesn’t buy it, I’m going for this.

What would you recommend?

I think I’d lean toward between stages:

“ Inserting Add-a-Stage between stages, such as before V2A in a Marshall, results in a tighter, leaner and more aggressive tone. The gain feels just a little higher and the attack is sharper. “

Yeah, I've tried it in a couple different types of amps. I've preferred inserted before V2A on both of them for sure.
