I have tried many new production tubes in my Fuchs Wild Card 100 to capture a verity of tones from Larry Carton, Robben Ford, Jimi Hendrix, Jeff Beck, ZZ Top, Heavy Rock, R&B, Punk, Country, 50's, 60's, 70's, 80's 90's and music of today. Last NR Gear Report I was trying out EH 6L6GC power tubes, Tong-Sol 12Ax7/803s Gold pin, Ruby JJ 83s, and Ruby Tube China 12Ax7A preamp tubes.
These were cool however when I got called for more styles of music these tubes did not get it. So back to the tube quest for tones. I went to my techs Jeremy Pratt and Todd Sharp at Nashville Amp Service https://amprepair.com who has done mods to my Fuchs Wild card 100. Jeremy sad hey man, have you tried the Svetlana RI 6L6GC tubes? I was like no, but heard bad things about them. Jeremy said you have to test them before installing and we have the test equipment to that. So I said go for it!
The Svetlana RI are more rounder in tone with slight more midrange and slight more bottom end then the EH 6L6GC. So when using this power tube, the JJ83's are to compressed and do not sound good nor do the Ruby Tube China 12Ax7A because of to much gain. The preamp tube combo that is very more versatile for all the range of music and work excellent with the Svetlana RI are these preamp tubes: in V1 which is tube for all channels is the Tung-Sol 12Ax7/803s Gold pin. The Gold pin I have found is a more reliable tube then the standard, In V2 which is only for the OD channel I went with Sovtek LP 12Ax7 this tube had less compression and gain then the JJ83s. The Sovtek LP gave the Fuchs Wild Card a more rounder, sweeter and added more highs to the overdrive tones; V3 PI, which is the phase inverter the Sino/China 12Ax7B, was the winner. The Ruby Tube/China 12Ax7A has more gain then the Sino/China 12Ax7B. So what happens is gets muddy and loss of highs. So the Sino/China 12Ax7B solved the problem.
Now the amp is happening for all types of music. The speakers also play a big part. These are the speakers I use. I will use a Jensen 1X12 Raptor or a Custom Weber Alnico 1X12 Legacy https://www.tedweber.com that they made for me. I'm now favoring the Weber in my NR 1X12 semi-open back cab. I also use a Mesa WideBody ported cab, I also had Weber speaker make me a custom 100w ceramic Blue Dog speaker, which I put in the Mesa. The cab came to life and is very musical. The other cabs are a NR ported 2X12 cab which has a Mesa C90 speaker and a custom Weber 100 watt ceramic Legacy speaker. And a Marshall 4X12 with 2 Mesa C90 speakers and 2 custom 100w ceramic Weber Legacy speaker. Also not only do these cabs and speakers sound good with the Fuchs Wild Card 100 they also sound good with Fender, Marshall and Bogner amps. I use the 2X12 and 4X12 cabs most with high wattage and gain amps. With 1X12 cabs have to be very careful with Marshall, Bogner and high gain amps. The 1x12 can't handle the volume and will blow the speaker!
Till Next time. Keep rockin’ my friends!
