Where to Add Reverb?

[kurtlives]

I am working on a preamp design. Right now it consists of a clean section which is two cascaded triodes. A dirty channel can be switched in by cascading another two triodes, for four triodes in series total.

I am working on adding a solid state buffered FXs loop in between the "channels". The FX loop has send, return and mix controls. It also has a bright switches and a series/parallel switch. It uses two FETs one being a source follower the other a gain stage (recovery).

Ok now I would like to add some reverb on top of all that. I was thinking of using one of those new Belton tanks and use the schem from GGG and tweak from there. Now I got thinking, where would I want to put this extra circuit?

I am really not sure...the clean channel dosent have any of what a guitarist would call distortion. Push volume all the way up and it doesn't sound dirty. That said it has a fair bit of output on tap. I am afraid the output's hot signal might overload the op-amps in the reverb circuit. That would be if the reverb was after the clean channel and before the FX loop.



I am really not sure. I hope what I wrote made sense. Any insight is appreciated.


Thanks...

OK, the clean and dirty are really one "channel" with gain stages added or removed? Look at a Dumble preamp and see where it goes there. I would assume it would be near the end of the signal path before a buffer.

Funny you mention that... I am working on a ODS amp right now. That's kinda where I am getting inspiration for this preamp.

But ya it follows a ODS in terms of the gain stages. It really is one channel with 2 gain stages either added or removed.

Right now I am either thinking before or after the buffered FX loop.

Take a look at this (Traynor YVC40 service manual)
On page 9: the effect loop is before the reverb (all solid state in a switchable tube preamp)
I might perhaps give you some inspiration.
