Today, I set up four different 4/10 bassman amps (Fender RI with Sovteks, Fender RI with Groove Tubes 6L6s and a NOS rectifier, A Hoffmaned Fender RI with all NOS tubes, and a Victoria with a variety of NOS and Sovteks) and and did side-by-side comparison. All rectifiers were 5AR4s.
I swapped out tube sets throughout the amps.
My conclusions can be summarized by looking at them on a scale of 1-10.
If the Victoria sound is a 10. The Hoffman is a 9.5, the Fender with Groove Tubes is a 9, and the Fender with Sovteks is an 8. It was that close. It was even closer when I dialed in each amps tone and presence pots to try to get the sounds to match. Once I had done this, the test players were not able to correctly, consistently guess which amp they were playing through.
I had my guitarist friend doing some of the playing and he is cancelling his Victoria order tomorrow, and keeping his Fender. And I am not putting in the Hoffman board. Money saved all around.
Now, if I had lots of disposable funds, and wanted that little extra edge, I'd consider the Victoria. Of course I haven't played the Sonny Jr. yet. Trying to set that up for this week.
Tubes, tubes, tubes. It seemed to make most of the difference in my tests.
I might also mention that the Victoria had a 5751 in for the middle preamp tube.
Here's a little tidbit. A friend of mine told me that Mark Baer from Victoria that the speakers in the Fender RI are the same as Mojotones, just different paint.
