Conventional tube-amp wisdom states that you get the most bang for your buck by replacing your pre-amp tubes. I’ve been a believer of this for quite awhile, and have tried out all sorts of pre-amp tubes in my amps over the years. A couple of days ago, I wrote that I had installed a new Mullard ECC83 (12AX7) into my Aracom VRX22. This particular Mullard is a Zaerix-labled ECC83 that probably came from the GDR (I didn’t look at the numbers – I really don’t care, for that matter). All I know is that it made a HUGE difference in the way my amp sounds. The overdrive instantly became smoother and more focused without top-end artifacts, and the notes are still very defined even at high overdrive settings on my amp.
The clip below says it all. I recorded this clip playing in the bridge pick up of Goldie, plugged straight into the VRX22, which then fed into the ever-so-awesome Aracom PRX15-Pro attenuator. The amp’s master, tone, and volume knobs were all set at 6 (about 2pm on the amp), and the clip was recorded at bedroom level!
To my ears, the VRX22 sounds like a much bigger amp than its 22 Watts! I’m really in tonal heaven right now!
