That old Fender Twin Reverb that I have has been sitting in a corner for years now not being used. It’s a great amp with unbelievable headroom. It is a 1979 after further investigation. I originally thought that it was a 1976 or 1974. Looking up the serial number determined this for me. This site is where I found out the year. Serial Number Lookup
When I pulled out the twin, plugged it in and started playing, I realized that it sure did have a really great sound that was completely different from the Vibrolux and Avatar 45. Nice and clean is what a Twin is for with hardly any breakup at all. The reverb wasn’t working and the power tubes seemed a little weak and it actually only had 2 power tubes in it which I always used to run it with.
I decided that I would spend a little of cash and fix this great amp up.
Here’s what the Final version was
– Replaced the 2 Vintage 30 Speakers with one WGS G12C/S 75 watt and one Celestion Greenback G12m.
– Replaced the Broken Reverb Tank with a MOD 4AB3C1B
– Put 2 new Power Tubes in – Groove Tubes 6L6-R Rating 4-7
– Pulled the V1 Tube
I also tried running the amp with only 2 power tubes and just one WGS G12C/S
All the amp settings were exactly the same for every video and the guitar volume was on 10 for the entire time for test validity. In each video, the WGS speaker was miced with a Shure SM 57. No eq or compression was used other than a master limiter to boost the volume for the audio tracks.
With Vintage 30 Speakers and 4 Power Tubes
With 1 WGS 12C/S and 2 Power tubes
With 1 Greenback and 1 WGS 12C/S
Here’s what the Final Version with Reverb sounds like and the V1 tube pulled.
I thought the WGS and Greenback made for a great pair, and I ended up staying with these two speakers. I do think that the Vintage 30’s sounded good, but not for what I wanted in this amp. I also think the Reverb sounds really great as well in this amp.
There are so many choices these days you can make with speakers, that sometimes it’s really hard to make a final decision. I’ll be using the Twin a lot more in future lessons and videos as there is no other amp that can really compare to this amount of clean, tube headroom in my opinion.
