I heard the ZenDrive II (tube) pedal the other day. Very nice sound for $250. Nik should make something like that, for $125!!!!

I had a dedicated preamp in mind though, no power amp section, no big OT.

Something with stereo returns and stereo record outs, with speaker emulation. Boogie and ENGL have such units. They've been making them for a very long time too.

Preamps fell out of favor after the 1990s. I still have no idea why. Many companies, like Matchless, Soldano, even crappy Marshall made preamps back then.

I agree, although "speaker emulation" might have some bearing on tone.

I know many people on the Gear Page think as I. A Class D style tube preamp would be the greatest invention since the bread slicer.

This is for Nik, in case he missed it in the Suggestions area.

Please!

1) stereo returns in the effects loop
2) speaker emulation on stereo record OUT

Now about the "voicing" original ODS, HRM, Bluesmaster?

Well I came up with an Overtone Preamp. Maybe not as many knobs as a FISH, but I think it would suffice for what you'd want.

Good one, although the new Boogie Mark V supposedly has a fine IIC+ setting.

So many people would love a Class D type, all tube, rackmount preamp. One with nice recording features:

1) stereo returns in the effects loop (mono send)
2) good speaker emulation on the REC out (stereo)
3) seperate MAIN OUT (no emulation)

4 to 5 12AX7s should cover all the features.  No power tubes or huge OT needed.

The world is your oyster Nik!
