Ah, the legendary silverface Twin Reverb. Often lauded as the perfect pedal platform, these amps are widely known for their glassy cleans and sky-high headroom. But there's more to this one than meets the eye.
Take a look under to hood, and if you know what you're looking for, you'll notice right away that this fella has had a few mods done to it. We'll get to those, but first, let's talk about what's original on it. The filter caps and transformers have been kicking since '79, and still going strong. That's about it.
Now, rather than typing a novel about everything that's been changed on this amp, we're just gonna list them:
- The coupling caps have been replaced with orange drops.
- The pull boost on the Master has been taken out.
- The Master has been modded to be post-phase inverter.
- The switch beside the Master controls the feedback between the power tubes and phase inverter. This changes the treble response and output level depending on where you have it set. A fairly unconventional mod, but pretty cool!
- The ultralinear taps on the output transformer have been disconnected, and switched to a regular screen voltage supply, similar to a blackface Twin.
- The "Output Tube Matching" has been converted to typical adjustable bias.
Now there's one last change to this amp that we're sure you're dying to read about. Let's talk about those speakers. Let's talk about those HUGE ASS MAGNETS. (insert Breaking Bad reference). The original speakers in this amp have been replaced with some Electro-Voice SRO/12 speakers, and they are BEEFY. I mean, just look at those things! There's no way they don't sound massive.
This amp has obviously been loved and gigged hard. It's got stains, tears, and dings throughout. But it works flawlessly, and it sounds amazing. Our expert amp tech here at EMS has gone through it and inspected it thoroughly to ensure it has a clean bill of health and is ready to perform.
Now in the spirit of full disclosure, this thing weighs a ton. Twin Reverbs are famous for being back-breakers, but the giant speakers that have been added to this thing make it particularly cumbersome. Like, "get your singer to help you lift it" kind of heavy. And for that reason, we ain't gonna ship this fella. It's got wheels on it, so you can hook a chain to your trailer hitch and tow it home. Okay maybe don't do that, but you're gonna have to come pick it up locally if you wanna get your hands on this guy.
Feel free to give us a call here at the shop if you have any further questions about this amp!
