Congrats! Building quite a tower there, Hunter. :) These preamps don't come around that much. They reckoned to be very good for classic (Fender) clean, tweedcrunch and classic drive. Not designed for heavy stuff though, so I understand the Cornford stays the first to call for big satured chords. I remember Groove Tubes made the Soul-0 series, nice combo's for vintagesounds. It looks like they are discontinued.
Probably I hang out too much at HugeRacksInc :)
Yeah they are a bit rare, not many clips out there. They had a 2x75W Poweramp to match the Trio, that was a beast, too. I got the Pre for a pretty good price. I could have had a Mesa Formula Pre for the same, but this one spoke to me more.
Now I'm gonna get a small Looper, 2xLoop or 4xLoop to hook it all up. I am already on rack an Midi anyways, so it's just gonna be another 70€ or so for the Looper finish the rig. I already have a Nobels MS-4 to switch the Trio. I'll go for a 6U rack with the Trio, the Korg DL8000R, Power Conditioner, a tray for switchers and loopers and power supplies and an empty space for maybe a reverb unit or a small power unit to go W/D/W later on.
The Korg does some pretty amazing mod effects too, hefty choruses, flangers and stuff. It's got 4 Delay lines, LFO, Env, all that stuff. Also a very unknown unit with amazing tones and capabilities. Not too straightforward to program, but it's worth digging in.
On my Midi Controller I'll set the bottom row for
1. Trio Clean
2. Trio Crunch/Hair
3. Cornford Crunch
4. Cornford Rock/Master 1
5. Cornford Lead/Master 2
Top row will be
6. My chain of Mod Pedals on the board In/Out (Phase/Chorus/Trem - I can still switch the pedals before)
7. Xotic EP Boost
8. Providence Delay in Front
9. Bypass for Rack Delay in Loop
10. Tap Tempo for Rack Delay in Loop
Plus I might program a bank or two with preset sounds, might also be using the Trio Ch3.
