ODS Preamp In A Box

[Eges]

So I’m making a 20 watish SSS02 with switchable CF, gain structure switch from two rock CRS and a presence knob. And will probably include fx loop so I thought while I’m at it why not build an ODS preamp to run at fx loop. What I am looking for is what Peace Hill FX does 2 tube preamp in stompbox format. Anyone has got a schematic?https://peacehillfx.com/pages/ods-tube-preamp

Edit: Actually the OD channel would be enough too since tone stack is same-ish.

I settled on OD channel only, anyone?

If it helps… I’m not sure I’ve ever seen one mentioned here.

If you search for SMPS you’ll find a couple of really impressive builds of SSS style preamps though, like this:

Perhaps they could help give inspiration for the power and general layout for your project?

Hmm maybe I can “paste” the od preamp to the power section of this

There are some good ideas for preamps on this forum. The recent SSS and Pentode preamps would be a good place to start. Those have an SMPS. I think it would be a bit of a challenge to build a dual triode preamp with a transformer in a stomp box, though it can be done.

Correction, I pointed you in the wrong direction. This is the one I actually meant. https://ampgarage.com/forum/viewtopic.php?f=4&t=36345

Oh yeah I got the schematic for this one. I don’t really need dual triode. “Overdrive” channel of ods is enough for me to run in fx loop to gain cascading

Oh btw would I need a clean blend in the box to be able to add the “ratio” control?
