Title: z-28 w/reverb
Post by: isaac_teller on February 26, 2020, 11:45:27 am

Hello. I am building a Z-28 and I would very much like to add tube reverb. Where would the best place be to insert it in the circuit? Thank you.

personally, I'd build it exactly as drawn, get it tweaked exactly the way I want, play it til I bleed then try a pedal verb in front, If I wasn't at least happy, I'd read and study all these examples

 til I settle on one or 2 and "add" it in.  You can "pre-plan" by cutting a tube hole between V1 and PI, even leave space on the turret board with a dozen or so "empty turrets" that can be used n jumpered.

I'd probably experiment with something like this.  This example is to show the insertion point and one type of "one tube reverb" that has worked well for me.

With respect, Tubenit
